Magnetic Contact Shutter Door

Crisp and dependable, this magnetic contact sensor is designed specifically for shutter and roller doors, providing reliable detection for security systems. It operates using a reed switch and matching magnet: when the door is closed and the magnet is aligned, the circuit closes; when the door opens and the magnet separates, the circuit opens, triggering an alert—perfect for perimeter protection.

Built to withstand industrial environments, its rugged metal casing, wide sensing gap (about 50 mm), and selectable NO/NC configuration ensure compatibility with various alarm setups and consistent performance even under high vibration or harsh conditions.
