1,200-lb Electromagnetic Lock, Status LED, Bond sensor, Door Position Sensor, UL Listed

The E-941Sx series of electromagnetic locks is the ideal way to secure a door against unauthorized entry. When power is applied to the electromagnetic lock, it creates an extremely strong magnetic field. The electromagnet is strongly attracted to the steel armature plate which is mounted on the secured door. Once the electromagnet is deactivated, the secured door will function normally without any residual magnetism.

Mounting Template

Doors lock, but can easily be forced open
  • Make sure the electromagnet and armature plates are properly aligned.
  • Make sure the contact surfaces of the electromagnet and armature plates are clean and free from rust.
  • Check the power leads with a meter, and make sure 12VDC or 24VDC is present.
  • Make sure the rubber washer is installed and free from damage.
Delay in door releasing
  • The electromagnet is fitted with a metal oxide varistor to prevent interference, so do not install a second diode.
  • Ensure that the control device is connected between the power source and the positive terminal of the lock
