Product overview
The WL3257 Tubular Push-Pull Solenoid is a compact electromagnetic linear actuator designed for industrial automation. Its cylindrical magnetic circuit provides high force density in a small envelope. Available in push, pull or push-pull configurations with configurable stroke, voltage and force to suit machine integration and control requirements.

How it works

• Electrical input: DC voltage applied to the copper coil.
• Magnetic field generation: current in the coil creates a magnetic field around the iron core.
• Plunger movement: the magnetic field draws the plunger along the tubular housing.
• Mechanical output: linear plunger travel produces pushing or pulling force on the load.
• Return: internal spring or external mechanism returns the plunger when de-energized.
• Output force depends on coil turns, current, magnetic material, air gap, stroke and mechanical design.

Main features

• High force density with precise stroke control.
• Cylindrical housing for improved magnetic efficiency and reduced friction.
• Compact dimensions for tight installation spaces.
• Customizable voltage, stroke, force level and mounting options.
• Manufactured with CNC machining, precision stamping, automatic coil winding and automated testing for consistency.

Applications

• Industrial automation and machine control: positioning, feeding and sorting systems.
• Robotics: locking, releasing, gripping and positioning mechanisms.
• Valve actuation for fluid, gas and pneumatic controls.
• Medical devices, pumps, testing equipment and laboratory automation.
• Security: electronic locks and access control systems.
• Vending machines, agricultural machinery, automotive systems, office automation and OEM equipment.
