Snap action limit switches are a type of sensing device. They are used to detect the position of a physical object and provide electrical signals to regulate the motion of the object. WLCA22N limit switch is a commonly used type of limit switch. This article will discuss WLCA22N\'s application fields and working principles.

Application Field

WLCA22N limit switch is widely used in a broad range of applications. It is widely used in material handling equipment and robotics. Due to its wide dynamic range, WLCA22N can detect the position of an object even in changing environments, such as in environments with dirt and dust that would affect other types of limit switches. Its ability to tolerate dust and various types of oil and direct contact with water and other fluids makes it suitable for controlling water level and oil level. Moreover, due to its robust design and dielectric strength, it is very suitable for use in hazardous environments, such as nuclear power plants.

Working Principle

WLCA22N limit switch with a mechanical actuator allows for a discrete switch positioned at a desired location. The actuator is a mechanical device that moves and actuates the switch when pressure, force or deflection is applied. The actuator is typically made of a metal bar and a spring. When the external pressure, force or deflection is applied, the metal bar moves and actuates the switch. The switch then sends out a signal to the load, thus controlling the motion of the object.

Besides the mechanical actuator, WLCA22N also includes electrical contacts that are used to switch electrical signals to the load. The electrical contacts are precision machined contact points that allow current to flow through when they are closed. Once the mechanical actuator is actuated, the contacts will close, allowing electrical current to flow through.

The WLCA22N limit switch can also be employed in an industrial environment to detect the presence of objects or mechanical movement. The limit switch uses an optical reflector-emitter sensor and a reflective surface to detect an object or mechanical movement. When an object or mechanical movement is detected, the reflector-emitter sensor will send out a signal to the load, thus regulating the motion of the object. The optical sensor information is collected by a processor and then used to control the motion of the object.

Conclusion

In conclusion, WLCA22N limit switch is a commonly used type of limit switch. It has a wide application field, being suitable for a broad range of applications, including material handling equipment, robotics, water level, oil level and hazardous environments. WLCA22N features a metal bar, spring and electrical contacts that actuate the switch when pressure, force or deflection is applied. In addition, it can also employ an optical reflector-emitter sensor to detect objects and mechanical movements.
