The 2202 series overhead door magnetic contact is for use in the rigorous environments of commercial and industrial applications. The floor mount units are constructed with a low-profile, heavy cast aluminum housing. The reed switch assembly is fully encased in GE Security's exclusive polyurethane potting material to prevent damage due to moisture or humidity.

A wide operating gap of up to 3 inches makes installation easy and helps prevent false alarms caused by loose-fitting doors. The contacts are available with a universal-style magnet that allows for greater installation flexibility.
