Holding solenoid WL0735B

lockingself-holdingcompact

Product overview
A push-pull latching solenoid is an electromechanical actuator that provides linear push and pull motion and remains latched in position without continuous power. A short electrical pulse changes the state; the plunger is held by a permanent magnet or mechanical latch, delivering an energy-efficient actuation suitable for automated systems and battery-powered equipment.

How it works
An electrical pulse energizes the coil and moves the internal plunger to the push or pull position. The plunger is retained by a magnetic or mechanical latch so no holding current is required. A reverse pulse or a dedicated release coil returns the plunger to its original state.

Key features

• Maintains position without continuous power (latching)
• Low heat generation during operation
• Fast response suitable for high-speed switching
• Compact footprint and low noise
• Long operational life (designed for high cycle counts)
• Configurable voltages, stroke lengths and holding forces

Industrial applications

• Industrial automation: locking mechanisms, sorting and handling systems, robotic actuators, safety interlocks
• Access control: electronic door and cabinet locks
• Vending and dispensing equipment
• Medical devices and portable instruments
• Automotive systems: electronic latches, seat or transmission mechanisms
• Valves and fluid-control equipment, IoT and battery-powered devices

Advantages

• Reduced power consumption (power only during switching)
• No holding current required
• Lower operating temperature and extended lifetime
• Precise positioning and quiet operation

Disadvantages

• More complex and typically higher cost than non-latching solenoids
• Requires pulse-control circuitry (reverse polarity or dual-coil) in many designs
• Holding force depends on magnet/latch design and may be limited for very high loads
• Can be affected by strong external magnetic fields or mechanical shock if not properly protected

Troubleshooting

• Verify correct supply voltage and pulse characteristics
• Inspect wiring, connectors and solder joints
• Measure coil resistance and check for open/short circuits
• Check for mechanical blockage, contamination or corrosion
• Confirm latch integrity and correct pulse duration
• Assess duty cycle to avoid overheating from excessive continuous operation

How to select

• Specify required push/pull holding forces and dynamic push/pull force
• Confirm needed stroke length (3–5 mm typical for this model)
• Choose operating voltage (DC 12V or DC 24V) and acceptable current
• Define duty cycle, switching frequency and response time requirements
• Verify mounting dimensions, environmental protection and operating temperature range
• Perform prototype testing for force, durability and electrical behavior
