Roller Shutter Magnetic Door Sensor

Description

Standard door contacts are rarely built to handle the rough physical dynamics of rolling metal shutters, industrial warehouses, or retail storefronts. Biosys Solutions Ltd provides the definitive solution with our industrial-grade Roller Shutter Magnetic Door Sensor—built to withstand heavy daily wear while keeping your perimeter securely monitored against unauthorized entry.

Rugged Zinc-Alloy Armored Construction

Unlike fragile plastic contacts that crack under foot traffic or constant vibrations, this sensor is encased in a high-strength, cast-zinc metal housing. Designed to be surface-mounted directly onto floors or heavy door tracks, it absorbs the impact of rolling metal curtains, delivery trucks, and high-frequency commercial use without compromising performance.

Reliable Wide-Gap Detection & Circuit Integrity

Rolling doors naturally shift and flex under wind pressure and manual handling. This sensor features an extended operating gap (up to 50 mm) and a high-quality internal reed switch that ensures a stable, consistent dry contact output. Configured as a Normally Closed (NC) circuit, any attempt to pry open, lift, or separate the magnet from the sensor breaks the loop, instantaneously firing your alarm control panel.

Seamless Alarm System Integration

Whether you are securing a retail shop in Nairobi CBD, a hardware store upcountry, or an industrial bay, this wired sensor integrates effortlessly into virtually any mainstream burglar alarm system using standard multi-core alarm cables. Its low-profile architecture allows discreet positioning, keeping the sensor protected from intentional tampering.
