Nascom N205AU/STSD Overhead Door Standard DPDT Switch with Universal Magnet and 24" Armored Cable, Silver

Built for dependable overhead door monitoring, the Nascom N205AU magnetic contact delivers reliable, low-maintenance protection for commercial and industrial security systems. Designed with No Dead Spot technology and an installer-selectable DPDT/SPDT contact configuration, this overhead door switch minimizes nuisance alarms caused by side-to-side door movement while giving technicians flexible wiring options for alarm panels and access control. The N205AU combines a strong N35 NdFeB magnet and an extra-wide 3" gap to accommodate imperfect alignments without sacrificing detection performance. A 24" armored cable and extruded anodized aluminum housing provide mechanical and environmental durability on high-traffic loading bays and exterior doors, while UL634 listing and a 30V DC/500mA rating meet common compliance requirements. Ideal for perimeter security, surveillance integration, and alarm monitoring on commercial facilities, the Nascom N205AU simplifies installation and reduces service calls.
