An electromagnetic lock is a device used to control the access through a door. It consists of an electromagnet mounted in or on the door frame and a matching plate that is affixed to the door. When energized, the electromagnet holds the plate with a retention force that may exceed 1000 lbs, thus effectively locking the door. BuyAccess.com carries electromagnetic door locks in a range of holding forces to suit different applications. They are typically controlled through security systems, keypads, key switches, card access systems, 'request to exit' buttons, and/or by special devices worn by persons who's safety could be comprised by uncontrolled egress.
