GRI 410-W 410 Industrial Surface Mount Switch Set, Standard Gap, 10W, 160VDC, 0.40 Amp, Closed Loop, N/O, A, White

Protect critical entry points with dependable, installer-friendly magnetic contact monitoring. The George Risk Industries 410-W industrial surface-mount magnetic contact is built for commercial and industrial security applications, delivering consistent door and frame supervision for access control, alarm monitoring and surveillance integration. With a standard gap of 0.5" and a normally open (N.O.) Form A contact, the 410-W reliably senses door position while minimizing nuisance trips. It supports up to 160VDC operation and consumes just 10W (0.40 A), making it suitable for a wide range of control panels and power systems.

Installers benefit from the surface-mount profile, screw-terminal wiring and included spacers and mounting hardware for fast retrofits on metal doors and frames. The unit’s steel construction and tamper-resistant terminal placement provide durable, long-term performance in demanding environments. An integrated end-of-line (EOL) resistor simplifies circuit supervision and reduces commissioning time. Backed by a lifetime limited warranty, the GRI 410-W is an economical, reliable choice for alarm contractors, integrators and facility managers. Specify the 410-W for your next access control or perimeter security project and streamline installation and monitoring.
