Working Principle:
Magnetic is composed of two parts: a part is permanent magnet and other part is a normally reed switch,when permanent magnet close reed switch(less 5mm), magnetic sensor is in working station(short circuit). when magnet separate,it is normal open state.

Features:
*This sensor can't work alone, it needs to work with wired alarm host or other electronic devices(within 0.5A/100V/10W), such as lights,etc.
*When the magnet together, the circuit is conductive( light on ); when the magnet separate, the circuit is not conductive(light off). For example: Install on the door, close door light on. open door light off.
*Application in access control and alarm system. It's ideal intrusion warning and automatic light-on device for homes, apartments, mobile homes, dorms, offices, hotel rooms, garages, etc.
*Excellent design, tiny and fashion. Easily drilling installation.
*Low-consumption design, more power-saving.
