1,500-lb Electromagnetic Lock

The E-941SA-1K5Q 1,500-lb Single-Door Electromagnetic Lock 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.

Product Information Sheet (PI)



  1. The electromagnet is fitted with a metal oxide varistor to prevent interference, so do not install a second diode.
  2. Ensure that the control device is connected between the power source and the positive terminal of the lock
  1. Check to make sure the wires are securely tightened to the terminal block.
  2. Check that the power supply is connected and operating.
  3. Make sure the rubber washer is installed and free from damage.
  1. Make sure the electromagnet and armature plate are properly aligned.
  2. Make sure the contact surfaces of the electromagnet and armature plate are clean and free from rust.
  3. Check the power leads with a meter, and make sure 12VDC or 24VDC ispresent.
  4. Make sure the rubber washer is installed and free from damage.
