These energise to release electromagnets are ideal for door locking mechanisms and access control or security, fire door holding, medical devices, feeder systems for automated packaging machinery, pick and place equipment and power generation.

The permanent magnet within the electromagnet sits behind a copper coil with an iron core, and when electricity is applied, the copper coil creates a magnetic field that redirects the permanent magnet and 'cancels' out the external magnetic field. From this, it creates an internal 'closed' circuit.

The outer shell is a sturdy bright nickel plated cylinder, passivated with body mounting. They are designed for demanding clamping and release applications.
