Holding solenoid WL1632

linearlockingsorting

Overview
The tubular push-pull solenoid is an electromechanical actuator that converts electrical energy into short-stroke linear motion. It features a tubular metal cylinder housing a wound coil and a movable plunger; the tubular enclosure confines magnetic flux to improve efficiency and achieve high force density in a compact package.

How it works
A coil wound on a bobbin generates a magnetic field when DC is applied, attracting the steel plunger toward the coil center. In a pull configuration the plunger is attached to the load and pulls it in; in a push configuration a non-magnetic pushrod is fixed to the plunger so that plunger travel produces an outward push. A return spring or external mechanism typically restores the plunger when de-energized.

Main characteristics

• Enclosed tubular metal case to reduce magnetic flux leakage
• Bidirectional push & pull actuation in a compact form factor
• Typical voltages: 6 V, 12 V, 24 V DC
• Stroke range commonly 3–30 mm (this SKU: 3–5 mm)
• Variants for intermittent or continuous duty; life cycles from ~100,000 to millions depending on configuration
• Force range from grams to several kilograms depending on model and stroke
• Construction: carbon steel housing with zinc plating; stainless options and custom finishes available

Product overview & typical values
The WL1632 is a tubular push-pull solenoid designed for standard DC systems, providing precise short-stroke linear actuation for industrial and technical applications. Typical uses include actuators in sorting and assembly equipment, locking and access control, medical analyzers, vending/office machines and HVAC valve control.

Advantages

• High force density in a compact package
• Reduced magnetic leakage due to tubular enclosure
• Low acoustic noise and good structural rigidity
• Push or pull functionality available from similar footprint
• Customization for voltage, stroke, force, mounting and ingress protection

Disadvantages & limitations

• Available force decreases with increasing stroke; best suited for short strokes
• Thermal management required for prolonged continuous-duty operation
• Long-stroke variants reduce peak force
• May be costlier than simple open-frame alternatives for some applications

Troubleshooting (summary)

• Verify correct coil voltage and continuity; undervoltage (~85% or less) can prevent operation
• Inspect wiring, connections and mechanical binding; clean plunger and bore if contamination increases friction
• Overheating indicates duty-cycle exceeded or insufficient cooling; select continuous-duty models or allow cooling intervals
• Check return spring and mounting fasteners if noise or irregular motion occurs

Applications
Industrial automation (sorting, assembly, packaging), electronic locks and latching mechanisms, medical analyzers and lab equipment, automotive small actuators, vending and office machines, HVAC and fluid control valves.
