Electromagnetic Door Locks


For use alone or as part of an access-control system, these locks use electromagnetic force to hold single doors closed. Control the locks with a push-button switch or keypad door control (sold separately). When power is interrupted, they instantly release. All locks must be hardwired.
Flush mount locks mount under the door frame header. For locks with 500 lbs. and 1,500 lbs. of holding strength, a 5/8" thick filler plate (sold separately) is required if the mounting surface on the frame is less than 2" wide.
Offset mount locks mount on the door frame header and include a mounting bracket that extends the strike plate above the door.
Locks with instant locking action lock doors as soon as they are closed. Those with delayed locking action lock doors after a set amount of time.
Optional battery backup packs supply power during power interruptions.

Electromagnetic Locks for Double Doors

For use alone or as part of an access-control system, these locks use electromagnetic force to hold double doors closed. Control the locks with a push-button switch or keypad door control (sold separately). When power is interrupted, they instantly release. The locks must be hardwired.
Locks include two strike plates to control two doors at once. They mount under the door frame header and lock the instant doors are closed. A 5/8" thick filler plate (sold separately) is required if the mounting surface on the frame is less than 2" wide.
Optional battery backup packs supply power during power interruptions.

Electromagnetic Gate Locks

For use alone or as part of an access-control system, these locks use electromagnets to hold gates closed. Remotely control these locks with a push-button switch or keypad control (sold separately). They lock automatically as soon as the gate is closed. When power is interrupted, these locks instantly release. The electromagnets include wire leads for easy electrical connection.
Assa Abloy Securitron locks are configurable to either 12V DC or 24V DC. They have a shock-absorbing strike plate that cushions the electromagnet, so the gate and lock won’t be damaged from impact as the gate door closes. Schlage locks are dual voltage rated for both 12V DC and 24V DC. They don’t require configuration.
Backup battery packs supply power for Schlage locks during power interruptions.
Filler plates are required for Schlage locks if the mounting surface is less than 2" wide.
Sliding brackets attach to doors that glide open horizontally. Swinging brackets attach to doors that push and pull.
