GRI 410PWG-B Industrial Surface Mount Switch Set, 3" Wide Gap, SPST-No, Brown

Protect industrial and commercial doors with the George Risk Industries 410PWG-B surface magnetic contact, engineered for reliable intrusion detection and access control monitoring. This wide-gap magnetic contact delivers dependable performance where heavy steel doors, misaligned frames, or large thresholds make standard contacts unreliable. The 410PWG-B features a 3.25" wide gap (Form A, N.O.) and a surface-mount profile with screw terminal termination to speed installation and reduce field adjustments. An integrated End-of-Line (EOL) resistor streamlines connections to alarm panels and simplifies supervision for security and surveillance systems. Constructed from rugged steel and UL-listed for commercial use, the switch set withstands harsh environments common in warehouses, manufacturing facilities, and utility sites. Backed by a lifetime limited warranty, it minimizes downtime and long-term replacement costs for facility managers and integrators. Ideal for perimeter security, access control, and intrusion monitoring projects — specify the George Risk 410PWG-B for reliable door contact performance in demanding installations.
