Snap Action, Limit Switches: WLS1A11AE Application Field and Working Principle

The WLS1A11AE series Limit Switch is a part of the wide range of limit switches available in the industry. It is a general-purpose switch, but was especially developed for applications where long life is of the utmost importance. It is used to detect limits of travel of moving and vibrating machine parts, such as in printing presses, packaging machines, etc. It is extremely robust, suitable for operation in tough applications, featuring an IP67 ingress protection rating and double insulated construction. The WLS1A11AE limit switch has two basic sets of functions: snap action and non-contact sensing. The snap action limit switch usually comprises of a lever head, plunger and calibration adjuster, which can be adjusted to set the lever\'s position and the actuation point. The plunger assembly generally consists of two parts, the mobile arm and the lock nut. The switch is actuated by pushing the plunger inwards, thus causing the mobile arm to engage the lever head and close the circuit. The switch can also be deactuated by releasing the plunger. The non-contact sensing method is similar- the lever and plunger are pushed inwards, but instead of closing the circuit, it activates a magnetic field which is detected by the sensor. The WLS1A11AE limit switch has a number of features that make it ideal for accommodating difficult applications. Firstly, it has an extremely robust construction, making it well-suited for extreme temperatures, shock and vibration. This ensures that even after long periods of operation, the unit\'s performance remains reliable. Secondly, the WLS1A11AE has two sets of limit switches- one for snap action and another for non-contact sensing. This allows the user to configure the unit according to the particular application. The third advantage is the maintenance-free design. The unit requires no additional maintenance, and can be installed and configured easily. Finally, the WLS1A11AE has a manual calibration option, which allows the user to set the threshold levels for the switch. To sum up, the WLS1A11AE limit switch is a specialised switch that is capable of accommodating difficult tasks. It is robust, reliable, and able to resist extreme temperatures, shock and vibration. The two sets of functions (snap action and non-contact sensing) allow the user to configure the switch according to the application. Finally, the manual calibration option permits the user to optimally set the threshold levels.

Conclusion

The WLS1A11AE limit switch is a specialised switch designed for heavy duty applications and is suitable for a wide range of automation tasks. It is robust, reliable, and able to resist extreme temperatures, shock and vibration. The two sets of functions (snap action and non-contact sensing) allow the user to configure the switch according to the application. Finally, the manual calibration option permits the user to optimally set the threshold levels in order to ensure reliable performance.
