George Risk Industries 150-12-W Recessed Contact Sensor White

Product Description

The George Risk Industries 150-12-W is a recessed magnetic contact sensor designed for door and window security applications. With a 1/2 inch diameter housing, this unit recesses cleanly into a drilled cavity in the door, window frame, or surrounding structure. It is rated to detect gaps up to 1 inch between the sensor and its magnet, providing reliable open/close detection. Electrically licensed security installers and alarm technicians are the primary installers of this type of device. The white finish allows it to blend into light-colored frames and trim without surface-mounted hardware.

Recessed contact sensors like the 150-12-W are used in residential and light commercial security and access control systems. They are installed wherever a low-profile, concealed contact point is needed — interior and exterior doors, casement windows, sliding doors, and similar openings. The unit ships individually and is sold as a single piece, making it suitable for spot replacement or new-construction rough-in work.

Installation Notes

Installation is typically performed by licensed alarm or low-voltage security technicians. A drill bit sized to match the 1/2 inch diameter housing is required to prepare the recess cavity in the door or frame. Disable or isolate the security panel zone before installing or replacing any contact sensor to prevent false alarms or panel faults. Follow local low-voltage wiring codes and the panel manufacturer guidelines when connecting sensor leads.
