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 forces up to 500 N for dependable clamping or locking applications.
  • Operates on 24 V DC or 240 V AC with Hirschmann connector interface and integrated rectifier options.
  • Nickel-plated finish with precision-machined face for maximum contact and durability.
  • Rear central mounting hole for easy installation and alignment in machinery or automation systems.
  • Recommended matching armature plates ensure optimal holding and contact efficiency.

Typical Applications

  • Safety holding systems that must remain engaged in power-off conditions.
  • Industrial automation, robotics, and machine guarding requiring fail-safe magnetic retention.
  • Door, gate, or hatch mechanisms using magnetic locks that release only on command.
  • Precision fixtures and handling systems needing repeatable, power-controlled magnetic release.
