Snap Action, Limit Switches - LSW6B application field and working principle

Snap action, limit switches are devices used to measure the position or movement of an object in an automated system. In particular, the LSW6B series is a series of snap action, limit switches designed by leading manufacturer Pepperl + Fuchs, specifically for use within the harsh environment of industrial machinery. The series boasts a range of environmental protections, ensures a high degree of reliability and is designed to be compatible with a wide range of machinery. In this article, we will explore the application field of the LSW6B and the working principle of its snap action, limit switches.

Application Field

The LSW6B series of snap action, limit switches are particularly suited for use in harsh environments such as those found in factories, mines and on factory floors. Its stainless steel casing provides a durable solution and makes the switch resistant to scratches and dust. The terminal and cable protection system on the LSW6B also ensures that the wiring is safe from elements such as water and dust, adding to its reliability. Additionally, the LSW6B’s quick response speed, reliable seals and durable construction are all key features that make it the ideal solution for heavy industrial applications.

The switch is also compatible with numerous other devices and can be used as a plug-in device with many motor controllers and PLCs, as well as traditional switchgear. Furthermore, the LSW6B also has certificates to CSA and UL standards and is available in both DC or AC versions.

Working Principle

The LSW6B series of snap action, limit switches are of the mechanical variety, using the snap-action force of a coil spring. In the switch, there is a plunger with a contact point and a moveable armature with a coil spring. When an object comes into contact with the plunger, the force of the plunger pushes the moveable armature. The coil spring causes the armature to snap back and change the contact point.

The head actuation remains in the switched position until another object contacts the plunger and forces the armature to change its state. This snap-action mechanism is used to detect the motion or position of an object quickly and reliably, making it ideal for use in high-speed automated systems.

Conclusion

The LSW6B series of snap action, limit switches have been designed by leading manufacturer Pepperl + Fuchs specifically for use in harsh industrial environments. The series offers a range of environmental protections and features, such as its stainless steel casing, terminal and cable protection and quick response speed making it an ideal choice for automation engineers. It is also compatible with a wide range of motor controllers and PLCs, as well as other traditional switchgear and boasts both CSA and UL certifications. The LSW6B utilizes a snap-action mechanism to quickly detect the motion or position of an object, making it ideal for use in high-speed automated systems.
