12、O 2005 All rights reservedIntroduction 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 a component or s

13、ystem. 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 in relationship

14、to the electrical power, a standardized pin assignment is required.

15、 International Standard specifies the pin assignment for pneumatic directional control valves when used together with electrical connectors according to IEC 60947-5-2. This definition is valid for connectors as shown in Figures D.2 and D.4 of IEC 60947-5-2:2004, which are shown in a simplified versi
