7939WG-BR HONEYWELL Magnetic Contact

Review HONEYWELL Magnetic Contact Brown

The Honeywell 7939WG-BR Magnetic Contact is a reliable and versatile safety device designed for use in various applications, particularly in environments where standard wired contacts may not be practical. This magnetic contact is part of Honeywell's 7900 series, known for their durability and ease of installation.

This magnetic contact operates on a simple principle: it consists of a movable probe or reed that is attracted to a permanent magnet when the normally closed (NC) switch is closed. When the magnet is removed or the switch is opened, the probe separates from the magnet, breaking the circuit and signaling an open condition. This design makes it ideal for monitoring the opening and closing of doors, windows, or other movable parts without the need for physical wiring.

The Honeywell 7939WG-BR Magnetic Contact is built to last, with a rugged, corrosion-resistant construction that can withstand harsh environments. It features a weather-resistant design, allowing it to be used both indoors and outdoors. The contact also comes with a built-in test button, enabling users to easily test the device's functionality and confirm proper operation.

Installation of the Honeywell 7939WG-BR Magnetic Contact is straightforward. It requires no wiring, making it a quick and easy solution for monitoring the status of doors, windows, or other moving parts. Simply attach the magnet to the moving part and the contact to a fixed surface, ensuring proper alignment for proper functionality.

The Honeywell 7939WG-BR Magnetic Contact is a valuable addition to any security or automation system, providing reliable and accurate monitoring of door and window openings and closings. Its durability, ease of installation, and versatility make it a popular choice among professionals and DIY enthusiasts alike.
