Custom Wound Electric Coils

At Endicott Coil Company, Inc., we have an expert engineering staff that specializes in custom electric coil winding assemblies. Our experience and versatility allow us to design and build any variety of coil type including air core, injection molded, impregnated, bobbin wound, and sensing coils. Our coils are built using 48 to 10 AWG sized wire in single layer, multi-layer, wet wound, dry wound, random layer, or precision winding configurations, depending on the application. Thermal Class insulations from 105°C - 240°C can be used and bobbins can be fabricated from Zytel, glass-filled nylon, Rynite, Ryton, LCP, Delrin, PEK or other custom materials as needed.

We use CNC winding equipment to ensure precision windings with tolerances as tight as .002". All of our custom coil winding assemblies are subjected to applicable hipot, resistance, inductance, leak, and surge testing to ensure our customers' specifications are met. Our tooling and machining is done in-house. We have experience serving the aerospace, nuclear, automotive, medical, and computer industries and meet all applicable UL, CSA, VDE, Mil-Spec, and NRC standards. Our commitment to innovation and quality has allowed us to meet and exceed our customers' expectations for over 50 years.
