More info


This sensor is a contactor to blades wrapped in an ABS housing. Normally, the blades are open (there is no connection between the two sons). The second part is a magnet. When the magnet is less than 13 mm (0.5 ") of the sensor, the blades are closed. This sensor is often used to detect an open door or window, that's why he has a support Assembly and screw. It is also easy to fix them with Scotch double-sided.
