Description
Eclipse Magnetics Energise-to-Release Electromagnets are electro-permanent magnetic assemblies designed to provide secure magnetic holding without continuous electrical power.
In their normal unpowered state, the magnets remain securely clamped. Electrical power is applied only when the magnetic hold needs to be released, making them suitable for controlled holding and fail-safe release applications.
The range is available in 35mm and 50mm diameter models, with both 24VDC and 240VAC versions available.
Typical applications include access control, security systems, fire door mechanisms, automation equipment, pick-and-place systems and other industrial holding applications.
Each magnet is designed to work with a recommended armature plate to achieve optimum magnetic performance.

Maximum holding force is achieved with full contact between the electromagnet and the recommended armature plate. Surface condition, alignment, material specification and air gap can reduce the achievable force.
