GRI 230-36 200 Series Floor Mount Industrial Overhead Door Switch, 3ft Armored Cable, DPDT, M-250 Magnet, Aluminum

Protect high-traffic industrial overhead doors with the George Risk Industries GRI 230-36 200 Series floor-mount magnetic contact. Designed for warehouses, loading docks and secure facilities, this industrial overhead door switch provides dependable monitoring and access-control performance even where heavy motorized traffic would destroy lesser switches. The extruded 6063 T5 aluminum housing is tested to withstand up to 20,000 lb of crushing force while the hermetically sealed DPDT reed contacts ensure reliable security and surveillance operation in harsh conditions. The unit ships with a 36" (#22 AWG) stainless steel armored cable for durable, protected wiring and includes mounting hardware plus a magnet bracket for fast installation. Standard features like plated contacts reduce sticking or freezing, and options such as built-in EOL resistors or supervisory loops make integration into access control and monitoring systems straightforward. Ideal for system integrators and facility managers who require rugged, long-life magnetic contacts for overhead doors — order the GRI 230-36 or contact us to specify longer leads or advanced supervision options.
