Linear solenoid WL4545

compact24-voltDC

Product overview
The AS 4545 push-pull solenoid actuator from Weilong Technology is a compact electromagnetic linear actuator designed for industrial and commercial automation. It converts electrical energy into controlled linear motion using an optimized coil and magnetic circuit within a carbon steel housing with zinc plating. The unit is available in standard 24V DC (12V option possible) and is suited for applications requiring fast response and short strokes.

Design & operation
The actuator delivers bidirectional (push and pull) linear movement with a stroke range of 5–8 mm. Its design emphasizes a balanced magnetic circuit and coil layout to provide stable response and repeatable force. Mounting is via three side holes for straightforward integration. Key electrical and mechanical parameters can be selected by engineers (voltage, stroke, mounting orientation) to match OEM requirements.

Applications

• Electronic locks and access control
• Vending and dispensing equipment
• Industrial automation and switch actuation
• Medical devices requiring short linear travel
• OEM control systems and intelligent mechanisms

Key advantages

• Compact footprint for space-constrained assemblies
• Fast, repeatable linear actuation for switching, latching and positioning
• Wide duty-cycle capability depending on configuration (design-dependent)
• Standard voltage options (24V DC; 12V available) for system compatibility
• Simple mechanical integration with three-side mounting holes

Limitations & design considerations

• Limited stroke compared with electric cylinders and motor-driven actuators
• Heat generation under continuous duty — requires appropriate duty-cycle planning
• Provides fixed linear motion only (no rotary or complex kinematics)
• Available force decreases with increased stroke — verify against application load
• Requires stable DC supply for consistent performance
