Fail-safe electro-permanent magnets for secure holding when unpowered. Available in 35 mm and 50 mm sizes with 24 V DC or 240 V AC options.

The Eclipse Magnetics Energise-to-Release Electro-Permanent Magnets provide reliable, controllable magnetic holding for automated, safety, and mechanical handling systems. These high-performance units operate on the principle of maintaining magnetic force without continuous power, energising only to release the load. Designed for secure holding under de-energised conditions, they offer a safe and energy-efficient alternative to standard electro-holding magnets. Available in 35 mm and 50 mm diameters, these robust assemblies are built to deliver consistent performance and long service life in industrial environments.

Key Features

  • Energise-to-release operation: magnet holds securely when unpowered, energising only to disengage the load.
  • High holding force: up to 500 N for dependable clamping or locking applications.
  • Dual voltage options: operates on 24 V DC or 240 V AC with Hirschmann connector interface and integrated rectifier options.
  • Durable construction: nickel-plated finish with precision-machined face for maximum contact and long service life.
  • Easy installation: rear central mounting hole allows simple alignment in machinery or automation systems.
  • Optimised performance: recommended matching armature plates help achieve maximum holding efficiency.

Typical Applications

  • Safety holding systems: remains engaged in power-off conditions for fail-safe retention.
  • Industrial automation: suitable for robotics, machinery, and handling systems requiring controlled release.
  • Door and hatch mechanisms: ideal for magnetic locks that release only on command.
  • Precision fixturing: supports repeatable holding in technical and engineered assemblies.

These electromagnets offer maximum pull force ratings from 285 N up to 471 N (approximately 28 kg to 47 kg, depending on size and application). Actual holding force achieved will depend on surface condition, alignment, and the use of the recommended armature plate.
