Overview - Energise-to-Release Electromagnet
The Energise-to-Release Electromagnet is an electro-permanent concept - a solenoid (wound copper coil) within a high quality high permeability iron assembly for high clamping forces and low magnetic losses plus a magnet build into the assembly. The iron cylinder of the Energise-to-Release Electromagnet is of sturdy design with a bright nickel finish passivated with body mounting. An electropermanent magnet is a specialised magnetic assembly that combines a permanent magnet and an electromagnet.
Armature plates (keeper plates) exist to suit each energise to release electromagnet unit. It has one central tapped hole on the rear face. Depending on the size, the energise to release electromagnet has two styles of electrical connection: Hirschman connectors and Hirschman style connectors.
The Energise-to-Release Electromagnet has, depending on the size, two supply voltages:- 24V dc and 240V ac. It also has a Duty Cycle of S2. The electromagnet has an IP rating of 54. They also have maximum possible pull force ratings from 285N up to 471N (28kg to 47kg) depending on the size of unit (the actual pull achieved will depend on the application).
Electrical power in the solenoid is required to the turn the magnet OFF. Power is removed to restore the magnet to ON. Pull force conversion (approximate):- 1kg = 10N = 2.2lb. The outer shell of this energise to release electromagnet is a sturdy bright nickel plated cylinder, passivated with body mounting. They are designed for demanding clamping and release applications. Typical applications include; door locking mechanisms for access control or security, fire door holding, medical devices , feeder systems for automated packaging machinery, pick and place equipment and power generation.

Advantages of Energise-to-Release Electromagnets
If no current is present, the unit will clamp to a ferrous surface using the internal magnet
Energy efficient – unit releases the hold only when you apply an electric current
Secure hold – does not need a current to clamp
Can clamp to any ferrous surface (maximum pull achieved with recommended armature plates)
