George Risk 50RS-12-B Mini Recessed Door Contact Brass

Product Description

The GEORGE RISK INDUSTRIES INC. 50RS-12-B is a miniature recessed door contact designed for use in security and alarm systems. This small-format magnetic contact mounts flush within a drilled hole in a door or window frame, keeping hardware hidden from view while maintaining a reliable normally-open or normally-closed circuit. The brass construction provides corrosion resistance suitable for interior installations. At 0.25 inches in diameter, the 50RS-12-B fits in a compact bore hole, making it a practical choice where space is limited or a clean finish is required.

This recessed contact is used in residential and light commercial security installations. It is typically installed in wood or metal door frames and doors to detect open or closed status. Alarm installers and low-voltage security technicians are the primary trade professionals working with this component. It is sold individually as a single unit, making it easy to order exact quantities for a given job.
