Understanding Analog Circuits - 07/28/2016

At Sag Harbor Industries, one of the products that we manufacture and supply to various industries is a magnetic coil. Magnetic coils are a key component in what is known as an analog circuit. An analog circuit can be found in a lot of older technology, like TV or radio antennas. We still use analog technology, but things are becoming increasingly digital. However, very common technology that we use every day like the car radio harnesses analog signals to perform its function. In this post, we’ll take a quick look at how an analog circuit works and why a magnetic coil is so important to the process. Let’s take a closer look!

Depending on the device, an analog circuit can either be very complex or very simple. A series of caps, resistors, coils, diodes and other basic electronic components need to be arranged together in a very specific way to create a functional device. In the midst of this set up, a magnetic coil is placed to transfer the electric current and create a magnetic field. This current passing through the magnetic coil is increased by the number of times the wire is turned, meaning that the more times the wire is turned the greater the size of the magnetic field will be. The magnetic core at the center of the coil is what helps to create such a strong magnetic field in the surrounding area. The point of a magnetic coil is usually to exert mechanical force on something so that the desired reaction happens or the desired machinery is activated. A time varying element can be added to the magnetic coil to create pulses of voltage for intermittent activation.

This is a very basic overview of how a magnetic coil functions in a magnetic circuit. There are many more complexities, but suffice it to say that a magnetic coil is very important to many analog functions.

What Exactly Do Air Coils Do? - 06/21/2016

An air coil is a special type of electromagnetic coil that is able to cause induction without using any ferromagnetic material. At the center of the coil is literally just a pocket of air. This is why it is also sometimes referred to as an “air core coil”. Because they are capable of handling such high frequencies, air coils are used for applications like microwaves where their high tolerance is still very important. Many military and aerospace devices also utilize air coil technology because the inductance caused by air coils is not disrupted by changes in the current.

Coils that are made with ferromagnetic coils tend to reach a peak even a moderate magnetic field strengths. In contrast, air coils have a very high range and can accommodate greater strengths. Most radios rely on air coils to help them transmit a clear signal. Air coils are also totally unaffected by “iron losses”. Iron losses affect ferromagnetic coils to a higher and higher degree as the frequency rises, so eliminating these all together with an air coil increases efficiency and limits distortion.

Due to the absence of a high permeability core, air coils are made with larger turns to facilitate the right inductance value. This isn’t really a problem at all when you are dealing with high frequencies, because you don’t need inductance in those situations. To limit any loss of energy that is caused due to presence of nearby electromagnetic radiation, air coils can be wrapped in a screen that provides protection.

Whether your product needs air coils, or some other type of electromagnetic coil, Sag Harbor Industries Inc. has the right solution for you. We can design and manufacture custom coils in a timely manner. Our state-of-the-art manufacturing equipment makes us ready to meet all of your needs and produce coils in high and medium order volumes. All of our products are 100% made in the USA. For over 65 years, Sag Harbor has been offering high quality electromagnetic solutions, so you can trust our experience and expertise. Call us today at 1 (800) 724-5952.

Inductors in Radio Equipment - 06/10/2016

The name “inductor” is just another term from an electrical coil. An inductor has two terminals and it passively resists changes in the electric current. The inductor stores energy in the magnetic field while the current is being applied. Voltage is induced only when the current passing through the inductor changes. Most inductors are built with a magnetic core that helps to increase the magnetic field and enamel coated wire is wrapped around the core to increase the magnetism. Inductors of varying sizes are used in a wide variety of common electrical applications, including radios. Inductors in radio equipment allow for an alternating current that is free from interference.

The inductors that are used in radio equipment are extremely small; sometimes they are only a few millimeters across and consist of a few small turns of wire. Because a radio is essentially an AC (alternating current) application, an inductor is necessary to make sure that the device reacts properly to AC signals of different frequencies. Without this small component, the radio would not be able to handle all of the variations in the incoming frequencies and it would be totally useless. As mobile electronic devices that use radio frequencies have become smaller and smaller, engineers have had to find ways to develop even smaller inductors. Some inductors are now just a fraction of a millimeter in length, making them small enough to be integrated into a circuit board without taking up the limited space in a mobile device.

At Sag Harbor Industries, we specialize in manufacturing inductors for a wide variety of products and applications. If the inductor you need doesn’t already exist in our line of products, we can work with you to create a custom inductor. Our design and engineering team is capable of creating a perfect customized solution for your needs. Once we’ve come up with a working prototype, we will put an optimized manufacturing process in place to make your custom inductors as efficiently as possible. We do all of this because we want to put our customers first by being flexible enough to meet their needs. That’s the Sag Harbor advantage.

Why You Need High Voltage Coils - 06/02/2016

Electromagnetic coils carry an electrical current from point A to point B to create a reaction that activates a device. Depending on the power source, the voltage that is passing through the coil can vary greatly. In some applications, like a car’s ignition system, the voltage is very high. To control and conduct this electricity, the system needs high voltage coils that are capable of safely using the energy. At Sag Harbor industries, we manufacture high voltage coils that are perfectly suited to your application. We can even work with your product engineers to develop a customized coil setup that works with your new product.

When it comes to working with electricity, safety should be at the top of everyone’s priority list. Too many preventable accidents take place every year because of poor electrical engineering or the use of components that cannot handle high volumes of electrical current. When you work with the experts at Sag Harbor, you’ll find that we take our manufacturing approach very seriously to produce quality products that operate efficiently in under any conditions.

As we mentioned above, high voltage coils can be found in the ignition system of a car. The coil helps to convert voltage from the car battery into sparks that are produced by the spark plugs to ignite the engine when the driver turns the key. The ignition coil is usually encased in epoxy or oil to help insulate and contain the high voltage that passes through when the battery is activated. Ignition coils are made to be strong and durable, not only to withstand the high voltage that passes through them, but also to continue working in the harsh conditions of a vehicle in any weather. A high voltage ignition coil is subject to heat, extreme cold, moisture, corrosion and a host of other variables.

Sag Harbor Industries manufacturers high voltage coils for clients in the automotive industry, as well as many other industries with high voltage power sources. Contact us today to learn how our expert engineers and technicians can create a customized coil setup for your product, or how one of our standard products could be used in your business.

Sag Harbor Industries - Coils - 04/05/2016

Coils are used in many electromagnetic, electromechanical and electrical applications that are needed in almost every industry you can imagine. From clocks to cars to medical equipment, coils are an essential part of many complex or simple items that we use on a daily basis.

An electromagnetic coil is formed when a conductive metal is wrapped around a core to create electromagnetic waves. This is necessary in situations where electrical currents interact with magnetic fields, like in a transformer on a power line. The shape of the coil increases the strength of the electromagnetic field when a current passes through it.

An electromechanical coil, perhaps known more commonly as a solenoid, uses a similar process. The purpose of the solenoid is to create a controlled magnetic field. The coil in a solenoid is usually wound around a steel or iron core. The level of control made possible by a solenoid can be very useful at short ranges because of its very quick response time. Fuel injectors in a car, for example, are usually controlled by solenoid so that they can turn on or off based on the demands made by the person driving the car. As soon as the ignition is turned to the ON positon, the fuel injectors need to be activated to send fuel to the engine, and they need to stop the moment the ignition is turned off again.

Electrical coils use all of the principles discussed above, but they are the most basic form of a coil. They can be made out of various kinds of metal based on their conductivity needs, and can be found in common units like household appliances.

The coils that are manufactured at Sag Harbor Industries are sold to clients in many lines of work. Our coils are all made right here in the USA, and we offer solutions for every possible type of application, from solenoid to electrical to molded coils and more! We even manufacture self-supported coils that can be used in irregular or uncommon applications.

Transformers: Making Things Work - 12/03/2015

The more electronics grow and evolve, the more frustrating they become to some people. Mostly due to the fact that there are so many different electronics to own and know how to use. From finding the compatible remote to turn on the Blu-ray player to knowing the right channel the game is on out of literally thousands of options, electronics can be a difficult thing to master.

One other complication that comes with a number of different electronic devices is that many of them require a different voltage level in order to function properly and safely. Nowadays most products come with their own transformers that manipulate the voltage from an outlet into the acceptable voltage that the product needs. Other times, a separate adapter must be purchased in order for all different products to work from the same outlet. Transformers work by taking electrical energy and from one electric circuit and then sending it to another without changing the frequency.

Now as technology advances and we see more and more electrical devices, a lot of manufacturers and companies are making their products a bit more user friendly by including transformers with their devices. If you happy to purchase a product or industrial machine that requires a transformer, be sure to check in with us to figure out which transformer is best suited for your unique application.

Pulse Transformers and Your Application - 11/13/2015

When talking about electric transformers, there are a number of different types that are able to provide different forms of power conversion for any number of specific applications or purposes. From high voltage transformers to low voltage transformers, they come in a variety of shapes and names such as auto, isolation, zig zag, pulse and toroidal transformers. Each name is based off of the functionality of the transformer. In this article, we would like to focus on the pulse transformer and mention a few applications where they can be found.

A pulse transformer interfaces a pulse forming network and a load, these transformers operate in a direct current mode. The reason they are called pulse transformers is because they release stored energy in a pulse. These transformers work at high frequencies normally, and require low loss cores. Pulse transformers are often found in detailing logic and telecommunications operations such as radar equipment, camera flashes, and even particle acceleration. A lot of times these transformers are used in electronic circuit applications, and in the digitization of computers.

Pulse transformers are born out of necessity as we continue to strive to reach our highest potential. As it is often said, necessity is the mother of invention. There are numerous kinds of transformers and each performs their own unique fashion that makes them ideal for specific applications. In order to know what is best for your application, contact us today and we will let you know if a pulse transformer will fit your application.

Getting to know Step Down Transformers - 11/04/2015

Step down transformers are often used to power appliances in other countries, they are also mostly used in power generating stations in order to increase the voltage while decreasing the current. These transformers can come in handy for traveling Americans as certain appliances such as a microwave are not quite as popular in foreign countries as they are here in America. In fact, some countries don’t even sell them. However, if you find yourself in a foreign land and have a need to use your microwave, a step down transformers is needed. These transformers allow for a decrease in voltage of electric currents to an acceptable level for the appliance.

As stated before they are often used in power generating plants for long distance transmission lines. The high voltages are paired with low currents and when the current reaches the receiving end, the voltage is lowered and the current is then increased in order to power the needed device. Because of their higher efficiency and lower losses these transformers are ideal for lowering voltage levels until they are right for home or business use. Smaller versions of these transformers can be used in televisions, electric razors and other portable electronic devices in order to the prevent short circuits or preventing the product from catching fire.

The transformer works through the electrical wiring that is around an electromagnet and by transferring the electrical energy through two coil stages. The first coil typically contains more wiring, while the second coil has fewer, this allows for the reduction in output voltage. Through this intricate system high voltage is converted to low current power and low voltage can be converted into high current power.

The Power of Low Voltage Transformers - 10/13/2015

Blowing a fuse is a common occurrence in households all around America. Electricity is a delicate thing to handle, too much and it can be hazardous and too little is its own problem. In order to ensure that the proper amount of power is going to a particular item, a transformer is required. Low voltage transformers can be a lifesaver in certain situations.

The common voltage levels of power outlets is typically around 120 volts, however not all devices need 120 volts, and a lot of them wouldn’t even be able to handle that much power. This is where low voltage transformers come into play. They can turn 120 volts into 12 or 24 volts, in order for small devices to operate properly without hazard.

These transformers are able to be very small because they do not need to process as much power as their high voltage transformer counterparts. Many times electronics are sold with their low voltage transformers included so consumers do not have to worry about damaging their new cell phone, camera, or media player. Occasionally, the low voltage transformer can be fitted directly in the device in order to keep things aesthetically pleasing while also keeping the product and user safe.

The Importance of Measurement - 09/28/2015

The world we live in often revolves around numbers, from the numbers in our bank accounts to the square footage of our homes to the number of cups of coffee we need in the morning. However, not everything is measure in the same units. Pizza’s come in a variety of slices, TV screens are measured in inches, and your cup of coffee holds 10 fluid ounces. Electricity is no different as it is measured by a certain unit; transformers measure the amount of current that is flowing in an electrical grid circuit.

Transformer manufacturers must take a number of factors into account when building a transformer to ensure accuracy. Some of the factors to consider include: burden class/saturation class, temperature, load, physical configuration, rating factor, external electromagnetic fields and many more. The build of an electric transformer is simply a primary winding, secondary winding and a magnetic core. The current flows in the primary creating a current in the second winding through the magnetic core. When both of these circuits are working properly an accurate reading can be produced.

Each country has a different way of measuring current transformers, so manufacturers must pay attention to the transformers destination while building it. The two main units of measurement are IEC 60044-1 (BSEN 60044-1) and IEEE C57.13 (ANSI). It is important to ensure constant electric supply through measurements to ensure we can all carry on with our day to day lives.

The Power of Electric Transformers - 09/15/2015

Electric transformers provide a safe way to bring electricity into our homes and power the things that we use in our everyday life. From our televisions to our kitchen appliances these machines convert the volts coming from our outlets to our electrical devices. The issue lies in that electricity is pumped out from power plants in large volumes and need to be converted down in order to be suitable for our electrical appliances. Many phone chargers carry small electric transformers in order to convert the electricity into a safe capacity to our phone batteries.

There are many different types of transformers due to the nature of the application. Zig Zag transformers for example, are a three phase power transformer that has the ability to filter and control harmonic currents and be used underground. The underground systems are useful in order to protect against earth faults.

Zig Zag transformers can offer numerous benefits over other transformers. They tend to be a simplistic design which makes them low in cost and can be easily installed onto existing systems. By keeping neutral currents local, these transformers are able to eliminate the need for large neutral wiring. They also improve the fundamental load current. While they are low cost, another cheaper alternative is the delta-wire transformer. The only issue being that this model is less effective than the zig zag model in some applications due to higher internal impedance.

The Danger of Solar Flares - 09/04/2015

Solar Flares are a growing topic among those in the scientific fields; these cosmic storms have the potential to cause a great deal of havoc to our planet. Now the amount of damage that these storms will cause all depends on who you ask. Some say that we could see the end of the world thanks to these solar flare storms others say we won’t see anything more than auroras across the sky.

While these storms are still somewhat of a questionable topic, the fact of the matter is that they carry consequences with them. We may be unsure of the scale of damage these consequences may have, there is no denying that they could cause a big disruption to our everyday life. There have been some minor storms that have already hit earth, but they didn’t result in anything more than auroras across the sky. If these storms were larger power grids, GPS, electric transformers and radio communications may fail.

One electric transformer being knocked out is not that big of a deal, those affected would be annoyed until it was fixed. But if hundreds of these transformers were knocked offline there would be major problems. So for now be glad that these storms have remained small and only provide us with spectacular light shows.

Transformer Industry Growing out of Necessity - 08/11/2015

There are a number of different electric transformers available that provide specific forms of power for numerous applications. From high voltage to low voltage transformers and all the types in between such as isolation, auto, zig zag, toroidal, and pulse transformers. Each of these transformers has a specific purpose and fits into very specific applications. It’s important to know what type of transformer you are looking for so that you can get the best possible result. In this post we will be taking a brief look into pulse transformers and what they have to offer.

Pulse transformers release stored energy in the form of a pulse; this is where they get their name. They typically operate in direct current and interface a pulse forming network and a load. Because these transformers operate at a high frequency they require low loss cores. Pulse transformers are often found in detail logic and telecommunications operations such as camera flashes, radar equipment, and particle acceleration. They are also found in the digitization of computers as well as in electronic circuit applications. Pulse transformers have even been used in the aerospace industry to alter the surface properties of some components. Pulse transformers are able to meet the very specific operating requirements for this application.

There are many types of transformers and the number will continue to grow as the manufacturing industry expands and processes evolve. As the industry evolves we will need more focused and specialized equipment in order to get the best possible end product. Always be sure to research your options before purchasing to make sure you are making the best decision for your needs and application.

Determining the Right High Voltage Transformer for You - 08/03/2015

Many different applications require the use of high voltage transformers. These transformers are used in cases where large amounts of electrical energy are involved, and they are usually used to convert large voltages to smaller voltages. Conversion allows low power electronic devices to run on the supplied electricity without being damaged or overheating. Like other transformers, high voltage transformers utilize magnetic induction between coils to make this conversion from high to low voltages. They can also incorporate other features like electrical isolation, power control, and instrumentation. High voltage transformers can be constructed in single-phase or three-phase configurations, which typically determine the size and cost of the device.

When looking for a high voltage transformer, it is important to consider your applications and the necessary features and capabilities of the transformer. Some of these specifications include the maximum secondary voltage rating, maximum secondary current rating, maximum power rating, and output type. A single transformer can supply more than one secondary voltage value, and transformers can be designed to provide AC or DC outputs. You should also consider the maximum primary voltage rating, as the transformer will need to be equipped with additional primary windings if you plan to use several nominal voltages.

Besides single-phase and three-phase, high voltage transformers can be constructed in many different configurations. Some of these include current transformers, step-down transformers, step-up transformers, auto transformers, isolation transformers, and more. They can also be built with laminated cores which are surrounded with a non-conducting material to help reduce electrical losses. Toroidal transformers are another option, and these transformers are constructed by wrapping copper wire around a cylindrical core, ensuring that the magnetic flux occurring within the coil doesn’t leak out and influence other components, which supports overall efficiency.

There are many different transformer options, and it can be a challenge to determine exactly what you need. However, discussing your applications with an experienced transformer manufacturer is always a good way to figure out the right solution for you and with the considerations mentioned here, you should be able to find exactly what you need!

The Transformation of Electrical Energy - 06/29/2015

As we all know, a fallen power line is dangerous. Not only are they dangerous, but they wreak havoc on those who lose power from them in their homes or businesses. Life seems to temporarily stand still. Luckily, fallen power lines do not happen often, but when it does happen, everyone’s lives need to adjust. In this article, you will learn about the basics of how power is distributed through the power lines and how transformers allow consumers to get power through the conversion of electricity.

There are many different types and sizes of electrical transformers, but the end result is the same. The purpose of transformers is to transform electrical energy by alternating the input to output of voltage levels. Transformers can be very larger in size like those that are installed at power plants, or very small for use in electronics. While they are used in many electrical devices, their main use is to transform power to provide electricity to the world. During the transformation of power, there are many transformers in use in order to make sure the power is converted in an efficient and safe manner.

Power plants generate power and it is then sent out to the world through electric lines. Since the power created at the power plants is very high in voltage, high-voltage transformers will be placed first in line to step-down the voltage. As the power decreases from transformer to transformer, it becomes safe for output into individual homes and businesses. Low-voltage transformers are then used to step-down the voltage levels for the last time on the outside. From the inside of buildings, electrical devices will internally step-down the levels for their own use.

High Voltage Coils - 05/31/2015

In response to the growing need of reliable coils, SAG Harbor Industries continuously researches and innovates to create the most cost effective and reliable products. As technology advances, a majority of newer applications require very strict power requirements and SAG Harbor is always adapting to the changing needs of the market.

Products that require low maintenance are easier for electric coil manufacturers to design more versatile coils. By equipping the coils with reinforced insulation, high voltage coils can be specialized to improve the quality and reliability of the coils. There are several methods of insulating electric coils, but one popular method is called vacuum pressure impregnation.

Vacuum Pressure Impregnation removes air, moisture and gas from the high voltage electrical coil while offering better heat distribution across the entire system. By providing an insulating epoxy, polyester or silicone resin in this type of electric coil insulation method, the lifespan, durability, and resistance to chemicals are greatly improved.

There are two primary types of high voltages coil which include Tesla coils and ignition coils. The average automotive ignition coil generally has an output of 30,000 volts and is known for its relativity inexpensive design. High powered Tesla coils can typically generate many megawatts of electricity and these products have a long history of experimentation for providing wireless energy. This technology has been heavily researched, but the concept of applying wireless energy to everyday applications has never taken full effect.

Isolation Transformers - 02/17/2015

Isolation transformers are designed to do one thing: isolate electricity. An isolation transformer works by separating the source of the electricity from the device the electricity is supplied to by distributing electricity to the device. Unlike most other transformers that change the voltage of electricity, isolation transformers are used to prevent unwanted electricity from escaping while still controlling the electricity transmitted.

Isolating the electricity is essential for many electronic devices, such as electric shavers, hair dryers, and straighteners. As a safety precaution, isolation transformers play a dual role by not allowing unwanted discharge from these devices over a sink. Much like a ground circuit, isolation transformers behave in the same fashion by reducing noise and stopping discharge.

Reducing noise is essential in a variety of electronics, such as televisions. Noise will cause the displayed image to be altered. In reverse, isolation transformers will improve unclear or fuzzy signals into clear ones. Isolation transformers are essential to improving and stabilizing our technology as well as making them safe to use.

Basics of Electrical Transformations - 01/05/2015

Electric transformers are used to transform electrical energy into different voltages. Conceptually, transformers alter the voltage from high to low or from low to high energy. The transformation of electrical currents allows electricity to be transported between power lines and wires so that it can power different types of applications. One example is the use of transformers that provide power through power lines that can be seen on the side of the roads. Depending on their application, electric transformers range in size, power level, and capability.

In essence, the main goal of transformers is energy transportation. In the case of light and power situations, the goal is to transform higher levels of voltage from power plants to lower levels of energy used in homes and businesses. Even appliances in your home have small transformers to reduce the power even more so that the device does not become overpowered and break. The most common type of electrical transformer is the three-phase transformer, but there are also single-phase transformers for use in lower energy levels.

Toroidal Transformers: What They Do and How They Work - 12/12/2014

Toroidal transformers are transformers made from a wire coiled around a circular magnetic core. This transformer model is actually the smallest type of transformer. Because of their size, they can be used to power products of all shapes and sizes. Battery chargers, amplifiers, medical devices, household appliances, lighting, and even industrial equipment all utilize these toroidal transformers, and they are found in the electronics, meteorology, security, transportation, aerospace, music, and many other industries.

These transformers allow electrical signals to be transferred from one circuit to another with a changed voltage without changing the signal frequency. The circular shape of these electronic devices allows for efficient use of space and provides protection from electromagnetic interference. Additionally, their shape does not allow for air gaps which provide low stray magnetic fields and make the component quiet and efficient. One added benefit is that these transformers accomplish all of this with minimal electrical energy loss.

The transformer core is fabricated from high magnetic permeability materials like iron and iron compounds which are formed into a ring or donut shape. Wires are then tightly wound around the core to form the primary and secondary coils. When an alternating current is introduced into the primary coil a magnetic field is generated within the magnetic core. This magnetic field then generates a current in the secondary coil. In this way the toroidal transformer transfers electrical energy from one circuit to another with an appropriate voltage for the secondary circuit.
