Energise-to-Release Permanent Electro Holding Magnets
Our Permanent Electro Holding Magnets combine the advantages of both permanent magnets and electromagnets. They consist of a permanent magnet encapsulated in a magnetic housing, with an excitation coil wound between the magnet and the housing.
Unlike standard electromagnets, this design ensures that the magnetic circuit is open in the “off” state, which allows the permanent magnet to provide holding force without the need for continuous current. This feature makes them particularly safe and reliable for holding workpieces, doors, or other components in the event of a power failure, or whenever long-term holding is required.
When a DC current is applied to the coil, the magnetic field of the permanent magnet is neutralized. As a result, the held part can be released with minimal effort. However, it’s important to note that some residual holding force may remain, unlike in conventional electromagnets, and this should be considered in the overall system design.
Because they require only a short pulse of current to switch states, these Permanent Electro Holding Magnets are highly energy-efficient and well-suited for applications demanding both reliability and low power consumption.

Compared to permanent magnets, electromagnets offer key advantages:
Adjustable strength.
Instant on/off capability.
High versatility for precise applications.
Applications of Electromagnets
Thanks to their controllable properties, electromagnets are widely used across industries:
Industrial automation & robotics: For actuators, locks, and motion control.
Lifting and material handling: Adjustable strength ensures precision and safety.
Magnetic separation: Separating metals in recycling and processing.
Scientific equipment: For experiments requiring controlled magnetic fields.
Their instant activation/deactivation makes them critical for systems needing on-demand magnetic control.
