Energise-to-Release Electro-Permanent Magnets | Ø35mm & Ø50mm | Up to 500N Holding Force

Eclipse Magnetics Energise-to-Release Electro-Permanent Magnets provide fail-safe magnetic holding for industrial automation, safety systems, machinery and controlled release applications.

Unlike conventional energise-to-hold electromagnets, these units maintain their magnetic holding force when electrical power is removed. Power is only applied when the load needs to be released, providing secure retention during a power loss while also reducing the need for continuous electrical consumption.

The range includes 35mm and 50mm diameter models with holding forces of 250N and 500N respectively. Both sizes are available for 24V DC or 240V AC operation, providing flexibility for integration into different machinery and control systems.

Their nickel-plated construction and machined contact face provide a durable magnetic holding solution for demanding industrial environments. A rear central mounting arrangement supports straightforward installation into automated equipment, locking mechanisms and engineered assemblies.

Energise-to-Release magnets are particularly suited to fail-safe holding systems, robotic and automated machinery, door and hatch mechanisms, material handling equipment and applications where a component must remain securely held if electrical power is interrupted.

For optimum holding performance, use the recommended matching armature plate shown in the technical data below. For additional sizes and controlled magnetic holding solutions, explore our wider range of industrial electromagnets.
