The gate opening detector is a magnetic contact that you can use to secure larger gates (garages). Unauthorized opening is detected and reported to the alarm center. The gate opening detector is mainly mounted on roller, sliding and tilting gates. The detector consists of a magnetic contact (reed) and a magnet. These are mounted parallel to each other. The circuit of this NC opening detector is closed in the idle state. If the distance between the reed and the magnet increases, the circuit is interrupted and an alarm is reported. The detector is protected against sabotage. The optimal installation location is in the middle of the driveway. The reed contact is mounted on the floor, the magnet - at a distance of approx. 20 mm - on the inside of the gate. The gate opening detector is ideal as a surface-mounted version. It is completely waterproof and dustproof (IP 68). Thanks to its extremely robust aluminum housing, it is protected against damage caused by driving over it.
