Linear solenoid WL0829

compactACelectromagnetic

Overview
An AC linear solenoid converts alternating current into linear motion. The WL0829 is designed for industrial automation and machinery and includes a copper coil, movable plunger, fixed iron core and a shading coil to reduce vibration and humming. It is available in multiple stroke and force variants for integration into control systems and valves.

Key Features

• Direct AC operation (no rectifier required)
• Fast response and strong initial pull
• Shading coil reduces humming and vibration
• Available in 6–8 mm stroke and multiple force ratings
• Compact carbon-steel housing with zinc plating for easy integration
• Models for continuous or intermittent duty

Advantages

• Simple adjustable-screw mounting for machine installation
• Cost-effective actuator solution for valves and mechanisms
• High cycle life (approx. 300,000 cycles)
• Voltage options: AC110V or 208V
• Wide operating temperature range: -10°C to 100°C

Disadvantages

• Audible noise higher than some DC solenoids if shading coil is not optimal
• Heat generation under prolonged continuous operation
• Position control less precise than closed-loop DC systems
• Potential vibration or reduced performance with incorrect shading coil or mounting

Troubleshooting (Common Issues, Causes & Solutions)

• Solenoid not moving
  • Possible causes: no power, incorrect voltage, loose/broken wiring, open coil, plunger jammed
  • Solutions: verify AC supply and voltage, inspect wiring, measure coil resistance, clean and lubricate plunger
• Weak or insufficient force
  • Possible causes: low/unstable voltage, coil overheating, excessive load, large air gap
  • Solutions: ensure correct rated voltage, improve ventilation, select appropriate force rating, reduce air gap
• Overheating
  • Possible causes: continuous duty beyond rating, poor ventilation, high ambient temperature, incorrect voltage
  • Solutions: use intermittent-duty model if required, improve airflow, verify voltage, choose higher duty-rated solenoid
• Noise or buzzing
  • Possible causes: missing/damaged shading coil, loose mounting, frequency mismatch, worn parts
  • Solutions: inspect/repair shading coil, tighten mounts, confirm frequency (50/60 Hz), replace worn components
• Slow or delayed response
  • Possible causes: dirt/debris, weak return spring, low voltage, coil aging
  • Solutions: clean internals, replace spring, stabilize power supply, replace aging solenoid
• Plunger sticking or not returning
  • Possible causes: rust/contamination, misalignment, damaged spring, side load
  • Solutions: clean and lightly lubricate, realign installation, replace spring, avoid side loads

Applications
Suitable for industrial automation (sorting systems, conveyors, packaging machinery), valve control (fluid and gas handling), vending/dispensing mechanisms, household appliances, laboratory and medical devices, door locking systems, textile and printing equipment. Customization available for stroke, force, voltage and mounting.

FAQ (Selected)

• What is an AC linear solenoid? — An electromechanical device that converts AC power into linear motion via coil, core and plunger.
• What does an AC linear solenoid do? — Provides linear actuation for valves, latches and mechanisms; shading ring reduces humming.
• Can AC solenoids run continuously? — Yes if rated for 100% duty; otherwise select intermittent models to prevent overheating.
• What is a shading ring? — A copper ring that creates out-of-phase magnetic flux to reduce vibration and humming.
