Sentrol's Miniature Surface Mount with Armored Cable overhead door magnetic contact is for use in 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. A wide operation gap distance of up to three inches makes installation easy and helps prevent false alarms caused by door movement or damaged and loose fitting doors.
