In a pneumatic circuit, what does it mean if the current flows through the reeds?

In a pneumatic circuit, when the current flows through the reeds, it typically indicates that the piston is at the advanced position. Reeds in a pneumatic system are often used as sensors that detect the position of the piston. When the piston moves to its advanced position, it activates the reed switch, allowing current to flow through it.

This behavior is crucial for the operation and control of pneumatic systems, as it provides feedback on the position of the piston, which is essential for automation and process control. The advanced position usually means that the pneumatic actuator has completed its intended task, such as extending to perform work or engage with another component. Understanding this feedback loop is vital for ensuring that systems operate efficiently and safely.
