Nascom N1178CB/SW120 3/4" Stub PTF Clear RX120

Reliable door monitoring that reduces false alarms and cuts install time. The Nascom N1178CB/SW120 3/4-inch Stub PTF Clear RX120 magnetic contact is engineered for residential, commercial and industrial hinged door applications where consistent security and discreet mounting are required. Its wide-gap design, powered by an N35 NdFeB rare-earth magnet, maintains contact integrity even on slightly warped or recessed doors, improving overall system reliability for access control and intrusion monitoring.

Installers benefit from a snap-fit mounting on steel (no glue required) and 12" 22 AWG wire leads for fast, secure wiring into alarm panels and surveillance systems. Encapsulated hermetically sealed contacts and a polypropylene housing protect against moisture and contamination, while the UL 634 listing gives you the code-level assurance needed for professional security projects. The compact 3/4-inch stub profile keeps the sensor discreet without sacrificing performance.
