The 2205 series overhead door magnetic contact is designed for use in environments where a heavy-duty unit is required. The floor mount units are constructed using a rugged low-profile extruded aluminum switch housing and a cast aluminum magnet 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.
