George Risk Industries 50F-12WG-B-BA Surface Mount Switch

Product Description

The George Risk Industries 50F-12WG-B-BA is a mini surface mount switch designed for wide-gap applications in security and access control systems. This compact reed switch assembly mounts directly to a door or window frame surface, sensing the position of the door or panel without requiring routed wiring channels. The brown housing blends with standard interior trim. Typical installers include alarm technicians and low-voltage security contractors working on residential or light commercial intrusion detection systems.

This switch is suited for installations where a standard-gap magnet switch is not sufficient, such as oversized door frames, thick door casings, or applications requiring greater separation tolerance between the switch body and the actuating magnet. The wide-gap design allows reliable triggering at greater magnet-to-switch distances than a standard mini surface mount unit, reducing false alarms caused by minor frame flex or door warp.

Key Features

• Wide-gap design allows reliable actuation at greater magnet separation distances
• Mini form factor for low-profile surface mount installation
• Brown housing finish compatible with standard interior door and window trim
• Surface mount configuration eliminates need for mortising or routing
• Sold individually as a single unit

Compatibility

Designed as an OEM-style replacement or new-installation surface mount reed switch for residential and light commercial door and window security sensor applications.

Installation Notes

Installation is performed by licensed low-voltage or alarm technicians following applicable local codes and manufacturer wiring guidelines. Disconnect or disarm the security system panel before installing or replacing any zone sensor. Mount the switch body to the fixed frame and position the actuating magnet on the moving door or window sash, maintaining the gap distance within the specified operating range. Avoid routing wiring across door hinges or areas subject to repeated mechanical stress.
