Final answer:
When a piston passes a sensor in the handling station, a proximity sensor or position sensor outputs a signal to indicate the piston's presence, allowing for precise control in automation systems.
Step-by-step explanation:
When a piston passes the sensor in a handling station, the device that commonly outputs a signal is called a proximity sensor or position sensor. These sensors can detect the presence of nearby objects without any physical contact. In an industrial automation context, such as a manufacturing line or a robotic assembly, proximity sensors play a crucial role in monitoring the position of components like pistons.
When a piston approaches the proximity sensor, it triggers the sensor to send a signal to the control system indicating that the piston is in position, allowing for precise control and coordination of mechanical movements. These sensors can be inductive, capacitive, ultrasonic, or photoelectric, each suited for specific environments and materials.
