WL1240 Latching Solenoid Actuator Industrial Application

Product catalog summary

Working Principle: The latching solenoid actuator operates through the interaction of a permanent magnet and an electromagnetic coil. The permanent magnet holds the plunger in position without power. A DC voltage pulse to the coil generates electromagnetic fields that either enhance or counteract the magnet's field, depending on the pulse polarity. This mechanism allows the plunger to change position, acting as a bistable switch that uses power only briefly (20-100 ms) during position changes.

Applications: Latching solenoid actuators are ideal for applications requiring power conservation and resilience to power loss. They are used in smart locks for doors, cabinets, and safes, ensuring they remain locked without electricity. In EV charging stations, they lock the charging plug to prevent unauthorized removal. They regulate water or gas flows in industrial equipment powered by irrigation or solar batteries. Household appliances like laundry machines and dishwashers use them to control water flow, conserving electricity. They are also used in portable gas flow controllers for oxygen concentrators, automotive devices like electronic parking brakes, and vehicle caps. Factories use them in counting machines, and they control solar collector positioning in renewable energy systems. Additionally, they are common in vending machines and locker doors for remote unlocking. Overall, they are suited for applications requiring control, power outage resilience, and low power consumption.

How does a latching solenoid actuator work? The latching solenoid actuator' s working principle is based on the interaction between a permanent magnet and an electromagnetic coil. A permanent magnet is responsible for holding the plunger in whatever position, which requires no power. Once a small DC voltage pulse is supplied to the coil, electromagnetic fields are generated that either enhance or interfere with the magnet' s field depending on the polarity of the pulse. If the generated field acts against the permanent magnet' s fields, then the plunger gets released from the lock and changes...
