Product overview
A magnetic push-pull solenoid is an electromechanical actuator that converts electrical energy into linear motion. The coil generates a magnetic field that attracts or repels an iron plunger to produce push or pull action. The WL7042 is a tubular push-pull solenoid designed for industrial automation and equipment requiring fast, repeatable linear actuation.

Advantages & limitations

• Advantages: compact size, simple integration, fast response, multiple voltage and stroke options
• Limitations: risk of overheating if used beyond rated duty cycle, reduced force at long strokes, potential noise during operation, requires stable power

Troubleshooting

• Check supply voltage and wiring for faults
• If overheating: reduce duty cycle or improve cooling
• Reduced force: verify voltage, stroke length and magnetic part wear
• Plunger sticking: clean or replace damaged components
• Abnormal noise: inspect mounting, springs and mechanical wear
