Feature

●[Specification] - Current: 0.5 A ; Voltage: 100 V ; Power Rating: 10 W
●[Dimension] - Cable Length:250 mm；Sensing Distance:15-25 mm；Lead type:1007UL#24AWG 260mm
●[Normally Closed] - N.C. means Normally Closed: When the magnet together, the circuit is conductive( light on ); when the magnet separates, the circuit is not conductive ( light off ).
●[Widely Usedl] - This Recessed Door Contact Sensor works with any access control or burglar alarm system available
●[Note] - the Magnetic Door Switch must be installed according to the sensing distance. It can only provide a switch signal to the transmitter. It cannot directly load the power, nor directly connect the lamp!


Description

Normally closed door sensor working principle: When the door and window are normally closed, the magnet is close to the switch, and the switch information is in the path state at this time; when the door and window are opened illegally, the magnet is switched on and off, and the switch signal is disconnected to initiate an alarm. Scope of application: door or window Installation method: during installation, the wire part is installed on the door frame, and the magnet part is installed on the door page. The two should be installed in parallel, otherwise it will shorten the sensing distance or fail. Note: Avoid installing around a strong magnetic field, high current environment, weak electromagnetic switch can not be directly loaded, do not directly connect to the power supply . When make order,pls check carefully!
