Magnetic Contact Detector SMK, Metal (Large)

The SMK magnetic contact detector is a simple and effective security alarm sensor for monitoring unauthorized access. It consists of two parts: a reed switch (magnetically operated sensor) and a magnet.

The large metal housing version is designed for installation on hangars, containers, garages, gates and other large structures where movement or opening must be monitored. When the contacts break, the detector sends an alarm signal triggering the security system.
