433MHz Wireless Door and Window Contact Sensor for Alarm Panels

✅ Watch a door open. The contact signals the panel when the magnet moves away from the sensor.

✅ Wire without a signal cable. Wireless transmission removes the need for a signal cable between the contact and the alarm host.

✅ Fit a small sensing point. The compact ABS body suits a narrow frame or window edge on a compatible opening.

✅ Pair with your panel. Set the sensor and magnet in alignment, then match the panel's wireless settings.

A wireless contact for your existing alarm panel

A 433 MHz magnetic contact sensor for a door or window that already reports to a compatible alarm panel. Mount the two parts in alignment on the opening and the frame, then pair them with the panel using the same wireless settings. A CR2032 battery is required and is not included, and the sensor does not work as a stand-alone alarm.
