Edwards Signaling 2202A-L | Magnetic Contact, Overhead Door-Mount, Floor-Mount, Surface-Mount, Closed Loop

The Sentrol 2200 Series overhead door magnetic contact is for use in the rigorous environments of commercial and industrial installations. The floor-mount units are constructed with a low-profile heavy cast aluminum housing. The reed switch assembly is fully encased in Sentrol's exclusive polyurethane potting material to prevent damage due to moisture or humidity. Reed legs are plated with rhodium or ruthenium and hermetically sealed in dry nitrogen. This offers superior protection against sticking and provides a moisture-free environment therefore preventing corrosion. A wide operating gap distance of up to 7.5cm makes installation easy and helps prevent false alarms caused by door movement or damaged and loose fitting doors. The Sentrol high-performance magnetic contacts have been designed to facilitate installation and ensure durability and dependability. Most are conservatively rated at 10,000,000 cycles, guaranteeing a long-life.
