Rotary solenoid WL490

Product Overview
The WL490 DC rotary solenoid is an electromagnetic actuator designed to convert DC electrical input into a controlled small-angle rotary motion. It provides defined angular indexing (typical angles: 25°, 30°, 45°, 60°, 90°, some types up to 95°) and is built with a coil, rotor (armature) and a return mechanism (spring or gravity). When DC voltage is applied the rotor turns to the indexed position; on power removal the return restores the initial position.

Main Features

• Fast response and high-speed switching.
• Compact footprint with favorable torque-to-size ratio.
• Accurate, repeatable angular positioning for predefined angles.
• Compatible with common DC voltages (12V, 18V, 24V and other options).
• Available duty options from intermittent to continuous depending on model design.

How It Works
Current through the coil generates a magnetic field that interacts with the rotor geometry (slots, helical grooves or shaped armature) to produce rotary motion. A spring or gravity return (or other mechanical return) repositions the rotor when power is removed. Certain designs include shaped armature features to achieve precise angular indexing.

Applications
WL490 rotary solenoids are suitable where compact, precise rotary indexing or rapid angular switching is required: sorting and packaging equipment, robotic actuators, smart locks and access control, automotive vent or fluid actuators, HVAC controls, diagnostic and medical devices, camera or optical drives, and general industrial automation.

Advantages & Disadvantages

• Advantages: rapid response, compact size, precise angular repeatability, good torque for volume, low maintenance, optional damping/noise reduction.
• Disadvantages: fixed/predefined rotation angles (limited continuous rotation), increased energy/thermal stress under heavy or continuous loads unless designed for continuous duty, and specific cooling or design adaptations required for sustained high-duty operation.

Important Practical Notes

• Switching times can be very short (sub-5 ms possible depending on size and load).
• Start and end torque can differ significantly—select model according to application torque profile.
• Standard mechanical options include various shaft configurations, return spring choices, metric or imperial threads, dust covers and tapped mounting holes.
• Optional viscous damping and noise reduction are available for smoother motion and softer end stops.
