A sensor magnet in housing is a permanent magnet that is epoxy encapsulated in a plastic or metal housing that is either cylindrical panel mount or adjustable screw mount, rectangular screw mount, or other custom mounted housing. Our sensor magnet products are used to actuate various magnetic reed sensors, hall effect sensor, and magnetic reed switches. The magnet is typically mounted to the moving part while the sensor or switch is mounted to a fixed surface.
