Product details

The DH-36 Recessed Door Contact (NO) is a wired magnetic sensor used in security and alarm systems to detect door or window opening.

This model works in Normally Open (NO) configuration, meaning the circuit remains open when the magnet is near the sensor and closes when the magnet moves away. This change of state sends a signal to the alarm panel or access control system.

The recessed design allows the sensor and magnet to be installed inside the door frame, making the device hidden and tamper-resistant compared to surface-mount sensors.

Built with a durable ABS housing and magnetic reed switch technology, the DH-36 sensor provides reliable detection for doors, windows, cabinets, and entry points in security installations.

You can buy this recessed door contact from ZZ Marts, with stores in Karachi and Lahore and delivery across Pakistan.
