The externally protected opening detector is ideal for reliable perimeter security. It is designed to secure doors and windows, detecting unauthorized openings and reporting them to the alarm control center. The opening detector consists of a magnetic contact (reed) and a magnet, which must be installed at a distance of at least 8 mm from each other, either parallel, end-to-end, or orthogonally.

In its idle state, the circuit of this NC opening detector is closed. If the distance between the reed and the magnet increases, the circuit is interrupted, triggering an alarm. The detector is protected against sabotage and external fields. External field protection means that only the magnet associated with this opening detector has the correct field strength to keep the circuit closed. Any change in field strength, for example, from a foreign magnet, interrupts the circuit and triggers an alarm.

The optimal installation location is the center of the door or window frame. Installation at the bottom of the window frame is also possible if a specific window is to be tilted while maintaining the secured magnetic contact. The detector is suitable for both surface-mounted and flush-mounted installation. It is waterproof and dustproof (IP 68). The opening detector is VdS certified and available in white and brown.
