29、er pressure within an enclosed circuit. Typical components found in such systems are pneumatic controls. These devices are used to regulate the function of a component or system.Some control components found in pneumatic fluid power systems are electrically actuated. For small control components wit
30、h electrical control mechanisms, plug connectors of round type with diameters of 8 mm and 12 mm are used. For a unified actuation of the control component in relationship to the electrical power, a standardized pin assignment is required. ISO 2017 All rights reserved vBS ISO 20401:2017BS ISO 20401:2
