The Screw Recessed Door/Window Magnetic Contact Sensor is a compact security switch used for monitoring access points like doors, windows, drawers, cabinets, and sliding panels. When the door or window is closed, the magnet aligns with the reed switch, keeping the circuit closed. If opened, the magnet separates and triggers an alarm or automation event, making it essential in intrusion detection and monitoring systems.
Designed for recessed installation using screw mounting, it fits seamlessly into frames without external visibility — providing a clean, covert installation suitable for homes, banks, offices, warehouses, data centers, and smart security automation setups.
Engineered for long-term stability with a high-sensitivity reed switch, it offers fast response, low power consumption, and reliable switching performance even in continuous use.
