Custom Coils Assemblies

Magnetic Sensors Corporation has earned a reputation for producing high quality and innovative custom coil assemblies for a wide variety of applications. Designing, engineering, tooling and manufacturing all performed in-house by MSC personnel. 

Our coils are used in a variety of ways: actuators, antennas, electromagnets, inductors, linear motors, sensors, and transmitters. Besides round wire coils, both flat and square magnet wire can be used if higher power density is required. Custom design, development, engineering, tooling, and manufacturing are all done in-house by our dedicated staff. We have the coil solutions you need.

MSC coils are typically wet wound with a proprietary epoxy. This is a labor intensive process, but it produces a tougher coil, less susceptible to resonance.
