Holding electromagnet WL 3031

lockingcompactpermanent magnet

Product Overview Permanent electromagnet combines a permanent magnetic circuit with an electrically controlled coil to provide a magnetic holding device that consumes power only during switching or release. This hybrid design delivers stable holding force with low continuous power needs, making it suitable for industrial automation, security locks, robotics and energy-sensitive systems.

Key Benefits

• Energy-efficient: power required only during state changes
• Consistent holding force for locking and clamping applications
• Compact construction with fast switching response
• Reduced heat generation and extended service life
• Compatible with battery-powered or low-energy installations

Applications

• Automation equipment: positioning, clamping and locking
• Security and access control: magnetic locks and latching systems
• Robotics: end-effector gripping and tool-change mechanisms
• Industrial machinery: fixture holding, valve actuation and precision movement
• Medical devices and consumer electronics requiring low-power, quiet operation
