GRI 4532D-36 Mini Overhead Door Switch with DPDT, 36" Armored Cable

Optimize perimeter monitoring and access control with the George Risk Industries 4532D-36 mini overhead door switch. This magnetic contact is engineered for commercial security and surveillance installations where durability and reliable signal integrity matter. The DPDT (Form C) contact configuration gives integrators flexible wiring options and redundancy for alarm panels, PLCs, or access control systems. A 36-inch stainless steel armored cable protects conductors from weather, wear and tampering—ideal for exterior doors, loading docks and industrial gates. The cast aluminum, hermetically sealed housing stands up to corrosive or high-traffic environments, while a wide working gap (up to 2.5–3") and universal magnet allow quick, forgiving alignment that reduces install time. Built-in options such as end-of-line resistors or diodes are available to simplify system wiring and supervision. Choose the GRI 4532D-36 for dependable, low-profile door monitoring that supports security, surveillance and building automation needs. Contact your distributor or add to cart to specify for your next access control or alarm project.
