Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

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 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 in relationship to the electrical power, a standardized pin assignment is required.

1 Scope

This document specifies the pin assignment for pneumatic directional control valves when used together with 8 mm and 12 mm diameter electrical round connectors according to IEC 60947-5-2. This definition is valid for connectors as shown in IEC 60947-5-2:2004, Figures D.2 and D.4, which are shown in Clause 4.
