Linear solenoid WL2551

lockingsortingminiature

Overview
The WL2551 linear tubular solenoid is a compact electromagnetic actuator designed for high linear force in a small cylindrical envelope. Its enclosed tubular steel housing improves mechanical stability, thermal behaviour and protection against dust and vibration, making it suitable for industrial automation and embedded OEM applications.

Key features

• Enclosed cylindrical housing for stability and environmental protection
• High force density relative to unit size
• Fast response and low operational noise
• Multiple voltage ratings and customization for stroke, force, shaft style and mounting
• Tubular design enhances thermal dissipation and longevity

How it works
Applying DC current to the coil generates a magnetic field that pulls the ferromagnetic plunger toward the coil center to produce straight-line (push or pull) motion. A return spring restores the plunger when current is removed.

Applications

• Automation: conveyor actuation, sorting mechanisms
• Locking & access control: electronic locks, latches, cabinet locks
• Vending and office equipment: dispenser and release mechanisms, printers
• Medical devices: compact actuator modules, diagnostic equipment, fluid control valves
• Automotive: switches, actuator mechanisms, gearbox locks
• OEM and embedded systems requiring compact, repeatable linear actuation

Advantages and disadvantages (summary)

• Pros: compact footprint; high force for size; quick response; simple reliable construction; flexible mounting and customization
• Cons: limited stroke reduces effective force for long travel; coil heating under continuous duty (requires thermal management); continuous power draw unless latching design is used; sensitive to radial/side loads; audible impact click; not inherently proportional without dedicated drivers
