GRI PBF-101T-B Open Push Button Plunger with Terminal, 3/4" (D), Brown

Optimize perimeter and access-point sensing with the George Risk Industries PBF-101T-B plunger switch — a rugged, retrofit-ready plunger and toggle switch engineered for security, surveillance and monitoring applications. The PBF flange design (0.75" x 1.5") installs without re-drilling, letting you replace problematic mechanical contacts quickly and reduce field labor. Its hermetically sealed reed contact and plated contact surfaces deliver long-term reliability and resistance to sticking or freezing, ideal for outdoor enclosures and high-use access control points. The adjustable screw plunger offers precise actuation (total travel .270", pre-travel .090" ± .040) for consistent trip points, while 12" 22AWG leads or screw terminals provide installation flexibility with alarm panels and control systems. Ships with spacers and mounting hardware for a ready-to-install solution; built-in E.O.L. resistors and diodes are available on request for seamless loop integration. Choose the PBF-101T-B when you need a dependable, low-voltage reed plunger that lowers maintenance and improves detection accuracy — perfect for security panels, surveillance housings and monitoring stations.
