IEC 61076-2-012:2020
(Main)Connectors for electrical and electronic equipment - Product Requirements - Part 2-012: Circular connectors - Detail specification for connectors with inner push-pull locking based on M12 connector interfaces according to IEC 61076-2-101, IEC 61076-2-109, IEC 61076-2-111 and IEC 61076-2-113
Connectors for electrical and electronic equipment - Product Requirements - Part 2-012: Circular connectors - Detail specification for connectors with inner push-pull locking based on M12 connector interfaces according to IEC 61076-2-101, IEC 61076-2-109, IEC 61076-2-111 and IEC 61076-2-113
IEC 61076-2-012:2020 specifies circular connectors with an inner push‑pull locking mechanism of a size derived from and thus being compatible with M12 screw‑locking connectors and with mating interfaces according to IEC 61076‑2‑101, IEC 61076‑2‑109, IEC 61076‑2‑111 and IEC 61076‑2‑113.
A female fixed connector with inner push-pull locking according to this document is intermateable with a correspondingly coded male free connector with M12 screw-locking according to IEC 61076-2-101, IEC 61076-2-109, IEC 61076-2-111 or IEC 61076-2-113.
This document covers both:
a) power connectors with current ratings up to 16 A and voltage ratings up to 630 V, typically used for power supply of electrical equipment used in industrial premises, and
b) connectors for data and signal transmission with frequencies up to 500 MHz.
These connectors consist of both fixed and free connectors, either rewirable or non‑rewirable, with M12 inner push‑pull locking as explained above. Male connectors have round contacts from Ø0,6 mm up to Ø1,5 mm.
This document covers various types of connectors identified by their "codings" with different contact arrangement, not mutually interchangeable.
The design of the inner push‑pull mechanism prevents the unintended mating of the male inner push‑pull free connector with the female connector with M12 screw‑locking even for identical coding.
Some styles of free connectors with female contacts covered in this document are equipped with both inner and outer push-pull locking for intermateability also with correspondingly coded male fixed or free connectors according to IEC 61076-2-010.
Connecteurs pour équipements électriques et électroniques - Exigences de produit - Partie 2-012 : Connecteurs circulaires - Spécification particulière relative aux connecteurs avec verrouillage interne de type pousser-tirer fondée sur les interfaces de connecteur M12 conformément à l’IEC 61076-2-101, l’IEC 61076-2-109, l’IEC 61076-2-111 et l’IEC 61076 -2-113
IEC 61076-2-012:2020 décrit les connecteurs circulaires équipés d’un mécanisme de verrouillage interne de type pousser-tirer dérivé des connecteurs à verrouillage à vis M12 et par conséquent compatible avec ces derniers, et avec des interfaces d’accouplement conformément à l’IEC 61076-2-101, l’IEC 61076-2-109, l’IEC 61076-2-111 et l’IEC 61076-2-113.
Une embase femelle équipée d’un verrouillage interne de type pousser-tirer conformément au présent document est accouplable à une fiche mâle codée en conséquence avec verrouillage à vis M12 conformément à l’IEC 61076-2-101, l’IEC 61076-2-109, l’IEC 61076-2-111 ou l’IEC 61076-2-113.
Le présent document couvre à la fois:
a) les connecteurs d’alimentation avec des caractéristiques assignées de courant de 16 A maximum et des caractéristiques assignées de tension de 630 V maximum, généralement utilisés pour l'alimentation des équipements électriques utilisés dans les locaux industriels, et
b) les connecteurs pour la transmission de données et de signal avec des fréquences maximales de 500 MHz.
Ces connecteurs se composent à la fois d’embases et de fiches, démontables ou non, avec verrouillage interne M12 de type pousser-tirer, comme cela est expliqué ci-dessus. Les connecteurs mâles possèdent des contacts arrondis de 0,60 mm à 1,5 mm de diamètre.
Le présent document couvre plusieurs types de connecteurs identifiés par leurs "codages" et présentant différentes dispositions de contact non interchangeables.
La conception du mécanisme interne de type pousser-tirer empêche l’accouplement fortuit de la fiche interne de type pousser-tirer mâle au connecteur femelle avec verrouillage à vis M12, même pour un codage identique.
Certains modèles de fiches à contacts femelles couverts dans le présent document sont équipés d'un verrouillage interne et externe de type pousser-tirer pour une compatibilité d’accouplement, ainsi que de fiches ou embases mâles codés en conséquence, conformément à l’IEC 61076-2-010.

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 61076‑2‑012 has been prepared by subcommittee 48B: Electrical
connectors, of IEC technical committee 48: Electrical connectors and mechanical structures
for electrical and electronic equipment.
The text of this International Standard is based on the following documents:

CONNECTORS FOR ELECTRICAL AND ELECTRONIC EQUIPMENT –
PRODUCT REQUIREMENTS –
Part 2‑012: Circular connectors – Detail specification for connectors with
inner push‑pull locking based on M12 connector interfaces according to
IEC 61076‑2‑101, IEC 61076‑2‑109, IEC 61076‑2‑111 and IEC 61076‑2‑113
1 Scope
This part of IEC 61076 specifies circular connectors with an inner push‑pull locking
mechanism of a size derived from and thus being compatible with M12 screw‑locking
connectors and with mating interfaces according to IEC 61076‑2‑101, IEC 61076‑2‑109,
IEC 61076‑2‑111 and IEC 61076‑2‑113.
A female fixed connector with inner push-pull locking according to this document is
intermateable with a correspondingly coded male free connector with M12 screw-locking
according to IEC 61076-2-101, IEC 61076-2-109, IEC 61076-2-111 or IEC 61076-2-113.
NOTE 1 M12 is the dimension of the thread of the screw‑locking mechanism of circular connectors with M12
screw‑locking.
This document covers both:
a) power connectors with current ratings up to 16 A and voltage ratings up to 630 V, typically
used for power supply of electrical equipment used in industrial premises, and
b) connectors for data and signal transmission with frequencies up to 500 MHz.
NOTE 2 The power connectors are not suitable as power distribution socket-outlets in electrical installations of
buildings.
These connectors consist of both fixed and free connectors, either rewirable or non‑rewirable,
with M12 inner push‑pull locking as explained above. Male connectors have round contacts
from Ø0,6 mm up to Ø1,5 mm.
This document covers various types of connectors identified by their "codings" with different
contact arrangement, not mutually interchangeable.
The design of the inner push‑pull mechanism prevents the unintended mating of the male
inner push‑pull free connector with the female connector with M12 screw‑locking even for
identical coding.
Some styles of free connectors with female contacts covered in this document are equipped
with both inner and outer push-pull locking for intermateability also with correspondingly
coded male fixed or free connectors according to IEC 61076-2-010.
