The Aeotec Door Window Sensor 7 (700 series) is a basic GEN7 sensor which detects if your window is opened or closed.

Thanks to its slim design, the Aeotec Door Window Sensor 7 can be inconspicuously on every window. The sensor just has to be installed on the window casement. Additionally, there has to be a slim magnet installed closely to the sensor at the window frame.

Should your Aeotec Door Window Sensor 7 (700 series) fail you once, the core - the circuit board - can be easily replaced without removing the sensor. This allows you to glue the device to the window frame and replace only the circuit board.
