Nascom N205AU/STHS Overhead Door High Security Set with Universal Magnet, Silver

Ensure dependable, false-alarm-free security monitoring for commercial overhead doors with the Nascom N205AU/STHS overhead door magnetic contact. Built for high-security applications, this magnetic contact set uses Nascom's NO DEAD SPOT technology to prevent nuisance alarms caused by side-to-side door movement, providing consistent closed-loop (N.O.) monitoring for alarm panels and access control systems. The universal mount and extra-wide 0.5" gap accommodate a wide range of overhead door profiles, reducing installation time and simplifying retrofits. Durable construction — extruded anodized aluminum housing, N35 rare-earth magnet, 36" 22AWG wire leads and 24" armored cable protection — secures wiring against wear in busy loading docks and industrial environments. UL634 listing and industry-standard switch mounting holes make the N205AU/STHS an easy choice for compliance-focused deployments. Ideal for perimeter security, surveillance integration, and door position monitoring in warehouses, manufacturing, and commercial facilities, this Nascom magnetic contact delivers long-term reliability and lower maintenance costs.
