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 61076-2-010 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:

INTRODUCTION
The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed
that compliance with this International Standard may involve the use of patent(s) concerning
the free connectors
The IEC takes no position concerning the evidence, validity and scope of these patent rights.
The holder of this patent right has assured the IEC that he/she is willing to give free licences
with applicants throughout the world. In this respect, the statement of the holder of this patent
right is registered with the IEC.

Part 2-010: Circular connectors – Detail specification for connectors
with outer or inner push-pull locking mechanism, based on mating
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 61076-2 specifies circular connectors with a push-pull locking mechanism of a
size derived from, and thus being compatible with M12 screw-locking connectors (free
connectors with screw-locking according to IEC 61076-2-101, IEC 61076-2-109,
IEC 61076-2-111 or IEC 61076-2-113 are compatible with push-pull fixed interfaces according
to this document) and with mating interfaces according to IEC 61076-2-101, IEC 61076-2-109,
IEC 61076-2-111 (except codings E in general and coding F for inner push-pull) or
IEC 61076-2-113.
A fixed connector with push-pull locking according to this document is intermateable with a
correspondingly coded free connector with M12 screw-locking according to any of the above
mentioned standards.
NOTE 1 M12 is the dimension of the thread of the screw-locking mechanism of circular connectors with M12 screw-
locking.
NOTE 2 IEC 61076-2-012 defines another inner push-pull for fixed female connectors which is however not
compatible to the inner push-pull defined in this document. Annex C shows the different styles of female free
connectors to extend male free connectors.
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 and power applications 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 push-pull locking as explained above. Male connectors have round contacts from Ø
0,6 mm up to Ø 1,5 mm. In addition, the push-pull mechanisms consist of 2 different push-pull
designs:
c) An outer push-pull for male and female fixed connector, where the locking groove is placed
onto the outer cylindric surface of the housing. The outer push-pull for female fixed
connectors is made for 2 different types of male connectors. It has locking means for both
types on its outer surface.
NOTE 3 For design and dimensions see 5.3.2 and 5.3.3.
d) An inner push-pull for female fixed connectors and for male free connectors, where the
locking means are placed onto the inner cylindric surface of the housing.
NOTE 4 For design and dimensions see 5.3.4.
The different codings provided by IEC 61076-2 series detail specifications mentioned within this
document prevent the mating of accordingly coded male or female connectors to any other
similarly sized interfaces, covered by other standards and the cross-mating between the
different codings provided by any other IEC 61076-2 series detail specification mentioned within
this document.
