Nascom N78G/ST Recessed 1" Wide Gap Standard Door Contact, Closed Loop, Normally Open, Switch/Magnet Set, Grey

Keep doors monitored and false alarms to a minimum with the Nascom N78G/ST recessed magnetic door contact. Engineered for security and access control applications, this 1" recessed wide-gap contact set provides dependable closed-loop (Normally Open) monitoring that withstands door shifting and environmental wear. The hermetically sealed, encapsulated contacts inside a durable polypropylene housing deliver long-term reliability for commercial, industrial, and residential installations.
