The Shutter Door Magnetic Contact Gap 50–70mm NO/NC Grey is a rugged intrusion sensor designed specifically for large-scale shutter and roller door security. Engineered for durability and reliable detection, this contact switch supports both normally open (NO) and normally closed (NC) configurations, offering flexibility in alarm system setups.
With a wide sensing gap of 50 to 70mm, this magnetic contact easily handles the larger tolerances found in shutter and industrial doors. The powerful internal magnet maintains stable performance, even on uneven surfaces or in high-vibration environments.
Supporting both NO and NC output modes, it works seamlessly with different alarm systems. This makes it suitable for integration into custom security setups, whether for triggering an alarm or activating other connected systems like lights or alerts.
The contact’s tough grey casing resists tampering, moisture, and mechanical damage. Its metal mount base ensures a secure fit on shutter door rails, while the compact profile allows low-visibility installation without interfering with door operation.
Installation is straightforward—screw it into place on the fixed and moving sections of the shutter. The unit connects quickly to standard security systems, reducing setup time and service interruptions.
