Heavy Duty Magnetic Reed Switch (GTR132)

This heavy duty magnetic reed switch set is designed to give a clear closed-position signal for automated gates, garage doors, shutters and similar access points. It uses a normally open contact that closes when the magnet comes within range, making it suitable for connecting to compatible controllers, alarms and automation systems. With a sensing gap up to 50mm, it offers more flexibility during installation where perfect alignment is difficult, such as on uneven posts, metal frames or high-use openings.The sensor and magnet are housed in zinc alloy for impact resistance and outdoor durability, with an IP68 rating to handle dust, rain and wash-down environments. It’s a surface mount setup and includes a 250mm 2-core 22AWG cable for straightforward wiring into low-voltage inputs. The compact form factor helps keep it discreet while still providing a robust physical build for residential, commercial and light industrial sites where reliable status feedback matters for safety checks, security monitoring and day-to-day access control.
