Encapsulated (Poured Epoxy) Coils

Custom is the keyword at Sag Harbor Industries. Our team of engineers has a long track record of creating innovative and creative solutions. Our staff of engineers is comprised of experts in relay, coil and computer aided design. Sag Harbor Industries is ready to partner with you to create encapsulated coil and other products of superior quality, durability and cost efficiency.

Our encapsulated coils are some of the best on the market. Encapsulated coils function similarly to that of solenoid coils except that these encapsulated coils due to the fact that they are coated in a resin that covers the wire. This means that encapsulated coils are much more efficient at protecting wires against moisture and other types of damage.

Because of this, encapsulated coils are considered to be a stronger type of electric coil. This also means that there are a number of different encapsulated varieties based on the type of industry that you are in. Here at SHI we offer a number of different options in order to provide you with the custom encapsulated coil that works for you.
