DH-33 Recessed Wired Door Contact – NC Magn...
Rs.450.00Product details
The DH-33 Recessed Door Contact Sensor (NC) is a wired magnetic sensor designed for alarm and security systems to detect door or window openings.
The sensor works using a magnetic reed switch and magnet pair. When the door is closed, the magnet keeps the circuit closed. When the door opens and the magnet moves away, the circuit opens and sends a signal to the alarm system.
Its recessed design allows installation inside the door or window frame, making the sensor hidden and more secure compared to surface-mount sensors.
The DH-33 sensor is widely used in home security systems, burglar alarms, access control systems, and commercial security installations where reliable intrusion detection is required.
