Overhead Door Contact
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.
