10、nd connectors of diameters 8 mm and 12 mm Introduction In pneumatic fluid power systems, power is transmitted and controlled through a fluid under pressure within an enclosed circuit. Typical components found in such systems are pneumatic controls. These devices are used to regulate the function of

11、a component or system. Some control components found in pneumatic fluid power systems are electrically actuated. For small control components with 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

12、in relationship to the electrical power, a standardized pin assignment is required. DIN ISO 20401:2007-07 5 1 Scope This International Standard specifies the pin assignment for pneumatic directional control valves when used together with electrical connectors according to IEC 60947-5-2. This definit
