Magnetic Door Open Sensor – N/C Type

Magnetic Door sensors are an essential component of your home security system : they let you know when someone is entering your home. These devices are made up of two parts, which form a circuit when they’re kept parallel to each other. When someone opens the door, the two parts separate and break the circuit, which triggers the control panel to sound an alarm.This is N/C type. In this the electrical circuit is ON when magnet is away from sensor(door in open position). Used in kitchen cabinet etc. to make led light ON when cabinet door opens.
The sensor alone can be connected only in low power ( less than 12 W) dc circuits. it can not directly connect to 230 v ac circuit. For that you will have to use a relay along with this sensor. we have the relay fitted version also for 230v ac.
