N400TB/STSD
Overview
Protect commercial entrances and reduce nuisance alarms with the Nascom N400TB/STSD industrial magnetic contact. Built as a single pole double throw set for demanding environments, this Nascom magnetic contact uses an N35 NdFeB rare-earth magnet to deliver an extra-wide gap that tolerates shifting or warped steel doors—keeping your security and monitoring systems stable. Encapsulated hermetically sealed contacts and ABS housing provide long-term durability, while UL634 listing ensures compliance with commercial security standards. Integrators benefit from predictable electrical behavior (30V DC, 0.2A input) and closed-loop contact signaling that maintains alarm integrity. Installation is faster and cleaner thanks to screw terminals, four-direction wire routing (including bottom feed) and a dedicated spacer for steel door installs. Ideal for access control, intrusion detection and surveillance projects, the N400TB/STSD minimizes downtime and false trips in high-traffic facilities. Specify the Nascom N400TB/STSD to improve alarm reliability on steel or oversized frames—order today or request a quote for your next security installation.
