Product Overview
The Weilong Rotary Solenoid WL0432 is an electromechanical actuator that converts electrical input into precise angular displacement (preset up to 90°). It produces controlled rotary motion using a coil-driven magnetic field and a return mechanism (spring or reverse polarity) for reliable positioning in industrial automation applications.

Key Features

• Compact rotary output with fast response suitable for automation and locking applications.
• Stable torque and high repeatability for accurate indexing and positioning.
• Multiple voltage options (DC 12V / 18V / 24V) and torque/power variants.
• Standard configurations include automatic return spring and configurable shaft/mounting options.
• Simple, serviceable construction enabling long service life with minimal maintenance.

Structure & Operation
The WL0432 comprises a coil, stator, rotor (armature), shaft and return spring. Energizing the coil generates a magnetic field that rotates the rotor to the preset angle (commonly 25°, 45°, 60° or 90°). Available in AC or DC variants and different mounting/shaft arrangements depending on application requirements.

Applications
Suitable for industrial automation (sorting, indexing, part positioning), locking and safety devices, HVAC actuators, office equipment (printers/copiers), automotive subsystems, electronic doors and selected medical devices where compact, repeatable angular motion is required.

Advantages & Disadvantages

• Advantages: Precise repeatable angular motion without complex linkages, compact footprint, fast actuation and low maintenance.
• Disadvantages: Limited to preset rotation angles (typical up to 90°), torque constrained for very heavy loads, possible heating under continuous duty and may require return springs or driver electronics for specific motion profiles.

Troubleshooting (selected highlights)

• No rotation: verify power supply, rated voltage, coil resistance and terminal connections.
• Weak/incomplete rotation: check voltage/current, reduce mechanical load and inspect for contamination or wear.
• Slow response: confirm supply stability, duty cycle, cooling and ensure correct driver circuitry.
• Overheating: check duty cycle compliance, correct voltage and heat dissipation.
• No return to neutral: inspect/replace return spring, remove obstructions and verify alignment.
• Noise/vibration: check mounting fasteners, shaft alignment and internal wear.
