Nascom N78G/STDD Recessed 1" Wide Gap Standard Door Contact Set, Double Pole, Double Throw, Switch/Magnet Set, Grey

Optimize perimeter security and reduce nuisance alarms with the Nascom N78G/STDD recessed magnetic contact. This magnetic contact set is engineered for security, surveillance, and monitoring applications on residential, commercial and industrial steel or wood doors. The 1in recessed, wide-gap design uses a powerful NdFeB rare-earth magnet and encapsulated hermetically sealed contacts to maintain consistent operation even when doors shift or warp.

Installers appreciate the snap-fit mounting on steel without adhesive and the 12" 22 AWG wire leads that speed field termination. The double-pole, double-throw (DPDT) switch configuration provides flexible wiring options for fail-safe circuits, dual-monitoring or auxiliary control functions. Constructed in rugged polypropylene and listed to UL634, the Nascom magnetic contact meets industry expectations for durability and compliance.

Use the N78G/STDD where reliable door position sensing and low-maintenance operation are critical—access control, intrusion detection, or integrated building monitoring systems. Add this Nascom magnetic contact to your next security project for a faster install and fewer false alarms.
