Pneumatic fluid power systems — Directional control valves — Specification of pin assignment for 8 mm and 12 mm diameter electrical round connectors

ISO 20401:2017 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.

Transmissions pneumatiques — Distributeurs de commande directionnels — Spécification de l'affectation des broches des connecteurs électriques ronds de diamètres 8 mm et 12 mm

Fluidna tehnika - Pnevmatika - Potni ventili - Specifikacija za kontakte za okrogle električne konektorje s premeroma 8 mm in 12 mm

Standard ISO 20401:2017 določa dodelitev zatičev za pnevmatske krmilne ventile, kadar se uporabljajo skupaj z električnimi okroglimi konektorji premera 8 mm in 12 mm v skladu z IEC 60947-5-2. Ta opredelitev velja za konektorje, kot so prikazani v IEC 60947-5-2:2004, sliki D.2 in D.4, ki sta prikazani v točki 4.

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.
