For best operation, ferromagnetic mounting or fixing materials should not be used.

Ferromagnetic Metal Detection Sensors

These Reed proximity switches operate when in the presence of magnetically conductive material. Instead of an actuating magnet, only a simple piece of iron is required to operate the sensor from the front or above. Applications include industrial, end travelling sensing limit switch in pneumatic cylinders, position control, functions control in plant and utility vehicles, security, door and window control, opening recognition contact and fire protection doors.
