Snap Action, Limit Switches – WLG2 Application Field and Working Principle

The WLG2 is an advanced type of snap action limit switch specifically designed for automation processes. The device operates using compression forces, and provides a reliable, repeatable service for industrial control needs, as well as other types of automation processes. This article will discuss the application fields and working principle of the WLG2.

Application Fields

The WLG2 snap action limit switch is best suited for use in automated assembly systems, robotics and material handling systems, as well as other industrial control and sensing applications. The device’s robust design and flexible configuration make it ideal for a wide range of use cases, such as:

• Piston/Cylinder Position Sensing
• Ramp and Cam detection
• Extrusion Applications
• Safety Interlock Circuits
• Robotic Joint Position Detection
• Control of Motors, Valves, Fans, and other Appliances

Working Principle

The WLG2 is a snap action limit switch made of a durable resin material to provide waterproof protection against harsh environments. The device operates on the principles of contact. Its two parts - the actuator and the armature - interact with each other when a force is applied. Depending on the force applied, the device can move from an open position to a closed position or vice versa. When the actuator moves, the armature moves along a cam-shaped track and pushes the contact block against the contact points. The contact block is connected to the armature with a spring, allowing the contact points to move smoothly. The contacts are then separated or joined together, depending on the movement of the armature. When the force is removed, the actuator and the armature return to their starting position.The WLG2 also contains a mechanical latching system to ensure reliable performance. The latching system prevents the contacts from establishing connection too quickly and controlling the motion of the actuator and armature.

Conclusion

The WLG2 is a great choice for industrial automation processes. Its contact-based operation allows for reliable and repeatable performance, while the latching system ensures safe and secure operation. Its waterproof design and wide range of use cases make the WLG2 an ideal choice for any industrial control or sensing application.
