Self Supported Coils

self supported coils

Self-supported coils (air coils) are the solution to uncommon, irregular or bobbin-less custom applications where space may be a concern. Sag Harbor Industries has the capacity to wind a wide variety of self-supported coils to meet your critical precision needs, special considerations and volume production requirements.

A self-supported coil is wound using a bondable magnetic wire, eliminating the need for a bobbin when space is limited. During manufacturing, this bonding is made possible by either heating the material in an industrial oven or through an induction process that uses solvents. Without a bobbin in the way, the coil can be wound even closer to the metal portion of a circuit. This close proximity enhances the magnetic possibilities in any application.

Coils for Every Application
