Electrically switched electro lifting magnet WL1625

handlingcompactelectromagnetic

Overview
An electric electromagnetic holder is a controlled device for holding, positioning and releasing ferromagnetic parts using an electromagnetic field. The WL1625 provides an on/off controllable holding function suitable for automation and material-handling tasks. Typical industrial uses include part holding, positioning and temporary fixation in manufacturing environments.

How it works
The WL1625 uses a wound coil and magnetic core to generate an axial magnetic field when energized. The magnetic circuit concentrates force at the contact surface so metal parts are attracted and retained. Removing power collapses the field and releases the part. Performance depends on coil design, voltage/current, air gap, contact area and core material; modern units can be integrated with sensors or control electronics for automated operation.

Applications
Electric magnet holders are used where repeatable, controllable magnetic holding is required:

• Robotic and assembly systems for part pickup and holding during processing
• Material handling and lifting of steel plates and components
• CNC fixtures, jigs and welding equipment for accurate positioning
• Security and locking devices requiring remote control
• Laboratory and testing equipment needing precise, repeatable fixation

Advantages and Disadvantages
Benefits

• Switchable holding force for controlled pick/place and release
• Fast response and high repeatability for automation cycles
• Compact form factor and easy integration with control systems
• Customizable voltage and mounting options to fit installations

Disadvantages

• Requires electrical power; loss of supply affects holding unless safety measures applied
• Coil generates heat under continuous operation requiring thermal management
• Initial cost may be higher than passive mechanical holders due to electromagnetic components

Troubleshooting (Common issues, causes and solutions)
1. Weak magnetic force

• Potential causes: insufficient operating voltage/current, excessive air gap, damaged coil or core
• Solutions: verify supply voltage/current, ensure full contact surface, inspect coil and connections

2. Magnet does not engage

• Potential causes: wiring fault, controller or driver failure
• Solutions: check wiring and connectors, test control signal, replace faulty components

3. Excessive heat generation

• Potential causes: prolonged energization, overcurrent, poor ventilation
• Solutions: reduce duty cycle, improve cooling, confirm rated parameters

4. Unstable or wobbly holding

• Potential causes: vibration, incorrect installation, insufficient contact area
• Solutions: secure mounting, select suitable model for load, adjust installation alignment
