Learn more about our Energise-To-Release Electromagnets

The Energise-to-Release Electromagnet is an electro-permanent device, featuring a solenoid (a wound copper coil) within a high-quality, high-permeability iron structure designed to achieve high clamping forces and minimise magnetic losses. Integrated into this assembly is a permanent magnet for added functionality. The iron cylinder housing the Energise-to-Release Electromagnet is robustly constructed with a bright nickel finish, passivated and equipped for body mounting.

An electropermanent magnet combines a permanent magnet with an electromagnet, enabling selective activation and deactivation. Depending on its size, the Energise-to-Release Electromagnet operates at either 24V DC or 240V AC and has a duty cycle rating of S2. Its IP54 rating indicates resistance to dust and water ingress. These electromagnets deliver maximum pull forces ranging from 285N to 471N (equivalent to 28kg to 47kg) depending on unit size, though the actual pull force will vary by application.

To deactivate the magnet, electrical power is supplied to the solenoid, turning the magnetic field off; removing the power reactivates the magnet. Approximate pull force conversions are as follows: 1kg ≈ 10N ≈ 2.2lb. The electromagnet’s outer casing is a durable, bright nickel-plated cylinder, also passivated and ready for body mounting. This design is ideal for demanding clamping and release tasks. Common applications include door locking mechanisms for access control and security, fire door holding, medical devices, automated packaging feeder systems, pick-and-place equipment, and power generation.
