602EN104-6

602EN104-6 is a type of snap-action limit switch, a device designed to detect the presence of an object or limit the travel of machinery. It works by detecting physical adjustments in appliances, such as a door being opened or a machine part reaching a certain spot. When this happens, the switch triggers a certain electrical S signal or instruction, allowing you to control and better manage the machine or appliance.

Uses

Snap-action limit switches are commonly used in a wide range of commercial and industrial applications. A few examples of uses include:

• Monitoring the position of a machine part and activating a machine function based on the part\'s adjusted position.
• Detecting the presence or the absence of objects and triggering an alarm if the expected object is missing.
• Automatically opening and shutting doors when an object passes within a certain range of the switch.
• Setting a machine part in motion and then triggering a function when the part is adjusted into its correct position.

Working Principle

The working of a snap-action limit switch is based on the principle of mechanical movement. As the device is triggered, a plunger moves back or forward and activates or deactivates the switch, triggering a signal. It is usually powered by electrical energy, however some models can also be powered by other sources such as air or water pressure.

The switch typically features a movable arm with a contact tip at one end, while the other end is fixed. The arm is placed in an electrically middle position, separating two electrical circuits, opening them and thus canceling out any type of electric current. When the arm is moved, the electrical circuits are closed and an electric current is passed through, thus triggering the switch and signaling a certain action.

Conclusion

Snap-action limit switches are extremely reliable and versatile devices, designed for a wide range of practical applications. They are easy to install and configure, and their simple and reliable design ensures they can be used myriad everyday tasks.
