Secure entrances discreetly without sacrificing performance. The George Risk Industries 2020-12 recessed magnetic contact provides tamper-resistant, concealed monitoring ideal for commercial doors, frames and perimeter access points. Designed as a 3/8-inch press-fit recessed switch with a 1/2-inch standard gap and normally-open (N/O) closed-loop configuration, this magnetic contact supports up to 200VDC at 0.50A to integrate smoothly with DC-backed alarm panels and surveillance systems. Its shorter case and softer fill protect the reed switch for long-term reliability, while polarized magnet options and optional PA-75 collars make it a practical choice for steel doors and challenging installations. With built-in EOL options and multiple lead configurations available, the GRI 2020-12 simplifies wiring, reduces service calls and helps maintain compliant, professional security deployments. Ideal for security integrators, facilities managers and surveillance projects — add this recessed magnetic contact to your next intrusion detection or access control installation.
