GRI 4532CL Miniature Overhead Door Switch Set, Gap up to 1/2", 24" Armored Cable Standard

Designed for dependable overhead door monitoring in commercial and industrial security systems, the George Risk Industries GRI 4532CL miniature magnetic contact delivers rugged, low-profile protection where reliability matters. This magnetic door switch set combines a cast aluminum, hermetically sealed housing with plated SPDT/Form C contacts to resist sticking or freezing and ensure accurate alarm reporting in harsh environments. With a working gap up to 1/2" and a standard 24" stainless steel armored cable, the 4532CL simplifies wiring runs while protecting conductors from vandalism and weather. The universal magnet mount and compact footprint let you retrofit existing doors without redrilling, making it ideal for access control, surveillance feed triggers, and perimeter monitoring. Optional built-in EOL resistors or diodes speed integration with alarm panels and monitoring systems. Backed by a lifetime warranty, the GRI 4532CL provides long-term, low-maintenance performance for low-voltage security installations.
