Connectors for electrical and electronic equipment - Product requirements - Part 2-114: Circular connectors - Detail specification for connectors with M8 screw- locking with power contacts and signal contacts for data transmission up to 100 MHz

IEC 61076-2-114:2020 describes circular connectors with M8 screw locking typically used for data and power transmissions in industrial applications. These connectors consist of fixed and free connectors that are either rewireable or non-rewireable. Data transmission performance is for Category 5 up to 100 MHz.
Two coded versions, identified as D-coded and P-coded, are provided that differ by their pin size and optionally by number of poles, hence by the function provided for field applications.
Male connectors have round contacts Ø 0,8 mm for D-coded, and Ø 1 mm for P-coded connectors.
The coding provided by this document prevents the mating of accordingly coded male or female connectors to any other similarly sized interfaces covered by other standards.

Connecteurs pour équipements électriques et électroniques - Exigences de produit - Partie 2-114: Connecteurs circulaires - Spécification particulière pour les connecteurs avec verrouillage à vis M8 avec contacts de puissance et contact de signaux pour transmission de données jusqu'à 100 MHz

IEC 61076-2-114:2020 décrit des connecteurs circulaires avec verrouillage à vis M8 typiquement utilisés pour la transmission de données et de puissance dans des applications industrielles. Ces connecteurs se composent d’embases et de fiches démontables ou non. Les performances de transmission de données de la catégorie 5 vont jusqu'à 100 MHz.
Deux versions codées, identifiées par codage D et codage P, sont prévues. Elles diffèrent par la taille de leurs broches et, facultativement, par le nombre de pôles, donc par la fonction prévue pour les applications de terrain.
Les connecteurs mâles possèdent des contacts arrondis de 0,8 mm de diamètre pour les connecteurs à codage D et de 1 mm de diamètre pour les connecteurs à codage P.
Les codages prévus par le présent document empêchent l'accouplement de connecteurs mâles ou femelles codés ainsi avec toute autre interface de même taille couverte par d'autres normes.

for connectors with M8 screw-locking with power contacts and

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
