What is the basic principle of a pneumatic limit switch?

A pneumatic limit switch operates on the principle of detecting the position of a moving component within a pneumatic system. When the pneumatic actuator reaches a predetermined position, the limit switch responds by either activating or deactivating a control signal. This mechanism allows for precise control and automation in various applications, ensuring that machinery functions correctly by indicating when a component has reached its intended endpoint.

The ability to detect specific positions makes pneumatic limit switches crucial for enhancing safety, improving operational efficiency, and automating processes in pneumatic systems. This functionality is central to their design and purpose, allowing for seamless integration into control circuits where positional feedback is necessary.
