OCB-25ST: Miniature Surface Mount Magnetic Contact with Screw Terminals

In residential and commercial perimeter intrusion protection, securing doors and windows with compact surface-mounted sensors requires reliable hardware that blends discreetly into frame aesthetics. The OCB-25ST is a professional miniature surface-mount magnetic contact engineered for versatile attachment onto wooden, vinyl, aluminum, and composite door sashes and window frames.

Miniature Casing & Integrated Screw Terminals

Designed with a low-profile, high-impact ABS plastic casing, the OCB-25ST features integrated screw terminals directly on the sensor body. This design eliminates the need for wire splicing or wire nuts inside tight mounting locations, allowing field technicians to connect zone cabling directly to the contact. The housing supports dual mounting options using either heavy-duty double-sided foam tape or standard mounting screws.

Reliable Reed Switch Sensing & Universal Integration

Equipped with a hermetically sealed internal reed switch, the contact offers a dependable operating sensing gap of 15 mm to 25 mm. This wide tolerance prevents false open alarms caused by door vibration, thermal expansion, frame settling, or minor hinge sagging over time. The OCB-25ST connects seamlessly into all hardwired conventional intrusion alarm panels, access control units, and automation monitoring loops.
