For reliable door monitoring and low-visibility installations, the Nascom N1178CB recessed magnetic contact delivers professional security performance for residential, commercial and industrial applications. This 3/4" recessed wide-gap stubby door contact is engineered to reduce false alarms—its wide-gap design and N35 NdFeB magnet tolerate door shifting and warping while maintaining consistent supervision. Installers benefit from a snap-fit design on steel doors that eliminates glue, speeds up labor, and reduces callbacks. The N1178CB features hermetically sealed contacts for long-term reliability and a SPDT (closed-loop) output with 12" 22 AWG wire leads to simplify wiring into alarm panels, access control or monitoring systems. Constructed from durable polypropylene and UL634-listed, this magnetic contact is suitable for steel or wood hinged doors where a compact, recessed solution is required. Ideal for security, surveillance and access control projects, the Nascom N1178CB provides a durable, code-compliant door sensor that minimizes downtime.
