Nascom N505AU/ST2CR Man Door Surface Mount Aluminum Steel Door, Dual Closed Loop Normally Open, 1FA, Switch/ Magnet, Silver

Protect high-traffic man doors with the Nascom N505AU magnetic contact — engineered for reliable security and minimal false alarms. As a purpose-built man door magnetic contact, the N505AU uses No Dead Spot™ technology and an N35 NdFeB rare-earth magnet to maintain a consistent 2.75" gap performance even when doors are slightly misaligned. The flip-switch universal mount speeds installation by allowing the cable to be routed in either direction without affecting operation. Built for commercial and industrial environments, the extruded anodized aluminum body and 24" armored cable lead protection resist tampering and physical wear. With 36" 22AWG wire leads and a dual closed-loop (normally open, 1FA) configuration, this Nascom magnetic contact integrates cleanly into access control, intrusion alarms and surveillance monitoring systems. Ideal for facility managers, security integrators and system installers who need dependable door contacts for perimeter and entry monitoring. Upgrade your entry protection — add the Nascom N505AU to your next access control or alarm project.
