Connectors for electronic equipment - Product requirements - Part 2-101: Circular connectors - Detail specification for M12 connectors with screw-locking

This part of IEC 61076 describes M12 circular connectors typically used for industrial process measurement and control. These connectors consist of fixed and free connectors either rewireable or non-rewireable, with screw-locking. The connectors with glass to metal seal are fixed connectors only which consist of fixed glass to metal sealed styles with rewireable male contacts and are intermateable with corresponding free connectors according to this International Standard. Male connectors have round contacts ? 0,6 mm, ? 0,76 mm, ? 0,8 mm and ? 1,0 mm.

Connecteurs pour équipements électroniques - Exigences de produit - Partie 2-101: Connecteurs circulaires - Spécification particulière pour les connecteurs M12 à vis

La CEI 61076-2-101:2012 décrit les connecteurs circulaires M12 qui sont généralement utilisés pour les mesures et les commandes dans les processus industriels. Ces connecteurs se composent d'embases et de fiches, démontables ou non et sont équipés d'un système à vis. Les connecteurs à joints verre-métal sont uniquement des embases constituées de modèles à joints verre-métal avec contacts mâles démontables et qui sont accouplables aux fiches correspondantes conformes à la présente Norme Internationale. Les connecteurs mâles possèdent des contacts arrondis de 0,6 mm, 0,76 mm, 0,8 mm et 1,0 mm. Les différents codages empêchent l'accouplement de ces connecteurs codés mâles ou femelles avec toute autre interface ainsi que l'accouplement croisé entre les différents codages. Cette troisième édition annule et remplace la deuxième édition parue en 2008 et son corrigendum paru en 2010. Elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:  - Les dessins de certains modèles ont été corrigés, Un nouveau modèle avec 17 pôles au maximum et un codage A, a été ajouté, car les nouvelles applications pour les dispositifs de mesure et de commande dans les processus industriels exigent un nombre élevé de pôles dans les connecteurs circulaires M12. Les modèles et les dimensions qui existent et qui étaient spécifiés dans la CEI 61076-2-101 Ed.2 sont toujours applicables pour la dimension d'interface ajoutée des versions à 17 pôles,  - Suppression de la désignation de type et des renseignements pour les commandes, les anciens Tableaux 6 et 7 ont été mis à jour en conséquence,  - Ajout du contenu technique de la CEI/PAS 61076-2-108, qui sera annulée après publication de la présente Norme Internationale. Les dessins ont été mis à jour et le titre de la Figure 9 a été corrigé. Mots clé: connecteurs M12, connecteurs circulaires.

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.
International Standard IEC 61076-2-101 has been prepared by sub-committee 48B:
Connectors, of Technical Committee 48: Electromechanical components and mechanical
structures for electronic equipment.
This third edition cancels and replaces the second edition published in 2008 and its
corrigendum published in 2010. It constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– The drawings of some styles have been corrected.
– A new style with maximum 17 poles, with A-coding, has been added, as new
applications for the industrial process measurement and control require a high number
of poles in M12 circular connectors. The existing styles and dimensions which were

dimension of the 17 poles versions.
– Removal of the type designation and ordering information, former Tables 6 and 7 have
been updated accordingly.
– Inclusion of the technical content of IEC PAS 61076-2-108, which will be withdrawn
after publication of this International Standard. The drawings have been updated and
correction to the title of Figure 9 was made.
