Compact DC Holding Magnet Product Overview
A DC holding electromagnet converts DC power into a stable attractive force without moving parts. The magnetic performance depends on coil power, core material, air gap and contact surface quality. WL10043 is optimized for continuous clamping in automated equipment where silent, precise holding is required.

How Does a DC Holding Electromagnet Work?
Applying DC voltage energizes the copper coil, generating a magnetic field that travels through the iron core and housing to create attraction at the contact face. Direct contact closes the magnetic circuit and yields maximum holding force.
Factors affecting holding force:

• Coil power and current
• Magnetic material and core design
• Contact surface flatness and finish
• Air gap between magnet and target
• Operating temperature
• Voltage stability and duty cycle

Highlights

• Rated holding force: 340 kg (typical)
• Compact footprint for space-constrained assemblies
• Low noise, no mechanical wear
• Designed for energy-efficient coil operation
• Available in DC 12V and 24V variants
• IP50 protection and precision machined housing
• Customizable mounting (M10 × 20 mm) and lead length

Applications

• Robotic fixtures and magnetic grippers
• Automatic doors, safety latches and locking mechanisms
• CNC fixtures, jigs and workholding in machining cells
• Inspection and testing fixtures requiring vibration-free hold
• Material handling, positioning and lifting aids
• Automated production lines and intelligent manufacturing cells

Advantages and Disadvantages
Pros

• High, stable holding force with fast activation
• Silent operation and minimal maintenance
• Compact design for easy integration
• Long service life due to absence of moving parts

Cons

• Generates heat under duty; cooling considerations required
• Holding force is dependent on power—no holding when de-energized
• Contaminated or uneven contact surfaces reduce performance
• Requires appropriate DC supply and control

Troubleshooting (common problems and solutions)
1. No power to hold

• Possible causes: missing supply, incorrect voltage, coil damage
• Solutions: verify wiring, check input voltage, measure coil resistance

2. Weak grabbing force

• Possible causes: excessive air gap, contaminated contact surface, undervoltage
• Solutions: clean contact faces, reduce air gap, confirm rated voltage

3. Overheating

• Possible causes: high duty cycle, overvoltage, insufficient cooling
• Solutions: verify duty cycle, improve ventilation/cooling, use rated voltage

4. Noise or vibration

• Possible causes: loose mounting, misalignment
• Solutions: tighten fasteners, align mating surfaces

5. Discontinuous operation

• Possible causes: loose cables, unstable power source
• Solutions: secure electrical connections, use regulated DC supply
