Description

The DH-56 Metal Door Magnetic Contact is a heavy-duty magnetic sensor designed for security alarm systems to detect door or gate opening.

This sensor uses a magnetic reed switch, an electrical switch activated by a magnetic field, commonly used in security systems to detect movement or door position.

The DH-56 model features a strong zinc alloy metal housing, making it suitable for metal doors, rolling shutters, industrial gates, and warehouse entrances where durability is required.

When the door is closed, the magnet keeps the circuit closed. When the door opens and the magnet moves away, the circuit changes state and triggers the alarm panel.

The DH-56 sensor supports both NO and NC output configurations depending on installation requirements and typically provides a wide operating gap of around 40 mm, making it suitable for large doors or shutters.

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