Electrically switched electro lifting magnet WL10050

for sheet metalhandlingcompact

Product overview
The WL10050 is a rectangular electromagnet designed for industrial magnetic attraction and hoisting applications. Its rectangular core increases contact area versus round cores, delivering stable holding force for ferromagnetic parts such as steel and iron.

Key features

• High holding force: Typical holding force around 80 kg.
• DC voltage options: Available in DC 12V, 18V and 24V variants (others on request).
• Compact footprint: Rectangular design for direct surface contact and efficient integration.
• Duty and temperature: Continuous-duty capable (1–100%) with operating range −10°C to 100°C.
• Construction: Carbon steel housing with insulated copper coil, lead wire 200 mm, screw-hole mounting.

WL10050 product details
The unit typically includes an iron core, insulated copper coil and protective casing. It is controlled by supplying the specified DC voltage; magnetic strength is proportional to current and can be adjusted through the power source or control circuit. Some variants include anti-residual-magnetism design or coatings for corrosion resistance.

Advantages and disadvantages

• Pros: Larger contact surface and higher holding power than round magnets; precise control via current; compact and adaptable; customizable voltage/size/force.
• Cons: Requires continuous power to maintain attraction; potential overheating in prolonged use (thermal management recommended); only works on ferromagnetic materials; improper design or overload can damage the coil.

Troubleshooting guide

• 1. Low magnetic power
  • Reasons: Insufficient or unstable voltage, poor contact or air gap, coil aging.
  • Solutions: Stabilize supply voltage; ensure flat contact surface; remove rust/contaminants; repair or replace coil.
• 2. Overheating
  • Reasons: Prolonged energization, inadequate cooling, high ambient temperature.
  • Solutions: Respect duty cycle; verify voltage/current; add cooling or choose high-temperature model.
• 3. No response
  • Reasons: Power supply fault, damaged coil, control circuit failure.
  • Solutions: Check wiring and supply; test coil with multimeter; replace faulty components.
• 4. Slow release or remanence
  • Reasons: Residual magnetism, circuit timing or mechanical sticking.
  • Solutions: Use demagnetizing pulse or reverse polarity; add mechanical release (spring); select low-remanence core.
• 5. Excessive energy consumption
  • Reasons: Incorrect voltage/current, degraded insulation, inefficient coil design.
  • Solutions: Use proper power supply; inspect insulation; replace with energy-efficient variant.
• 6. Mechanical fastening issues
  • Reasons: Loose screws, vibration, incorrect installation.
  • Solutions: Secure hardware; add anti-vibration measures; follow installation guidelines.
• 7. Coil damage or burnout
  • Reasons: Overvoltage/overcurrent, overheating, insulation failure.
  • Solutions: Install protection (fuses/thermostats); use voltage regulators; replace burned coils.
• 8. Residual magnetic field
  • Reasons: Core hysteresis, continuous energization.
  • Solutions: Design with anti-residual features; apply reverse pulses; select suitable core material.

Applications
Common in automation and robotics for positioning metal parts, material handling and lifting steel plates, packaging and sorting systems, magnetic locks, automotive welding and testing fixtures, magnetic clamps and industrial jigs. Custom designs available for specific requirements.
