OCB-24ST

OCB-24ST: Surface Flange Mount Magnetic Contact with Screw Terminals

In residential and commercial intrusion alarm installations, protecting perimeter doors and windows using surface-mounted contacts requires hardware that combines clean aesthetics with fast field installation. The OCB-24ST is a versatile flange-mount magnetic contact engineered with integrated mounting ears for secure attachment along door jambs, window frames, and cabinet enclosures.

Flange Mount Casing & Integrated Screw Terminals

Featuring a low-profile ABS plastic housing with side mounting flanges, the OCB-24ST mounts directly onto flat surfaces using standard screws, ensuring stable positioning without sliding out of alignment. The unit incorporates built-in screw terminals on the contact body, allowing installers to connect zone wiring directly without wire nuts or soldering inside tight frames.

Reliable Reed Switch Sensing & Universal Integration

Equipped with a hermetically sealed internal reed switch mechanism, the contact provides a reliable operating gap of 15 mm to 25 mm. This sensing range accommodates natural thermal expansion, door sagging, and frame movement without generating false open alarms. The OCB-24ST connects seamlessly into all hardwired conventional intrusion alarm panels, access control systems, and automation controllers.
