About the N78CG/ST

Recessed 3/4" wide gap door contact for residential, commercial, and industrial applications on steel and wood doors. Snap-fit installation on steel surfaces eliminates adhesive requirements and reduces installation time while minimizing false alarms from door shifting or warping.

Encapsulated hermetically sealed contacts resist environmental interference. 12" 22 AWG wire leads enable flexible positioning. Polypropylene housings provide durability across door types. Wide gap design utilizes N35 NdFeB rare earth magnet for reliable operation. UL634 listed for safety compliance.
