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.

A PAS is an intermediate specification made available to the public and needing a lower level

of consensus than an International Standard to be approved by vote (simple majority).

IEC PAS 61076-2-010 has been processed by subcommittee 48B: Electrical connectors, of

IEC technical committee 48: Electrical connectors and mechanical structures for electrical and

electronic equipment.

Following publication of this PAS, which is a pre-standard publication, the technical committee

or subcommittee concerned may transform it into an International Standard.
An International Standard is under preparation by IEC SC48B, to be published as

IEC 61076-2-010 (if approved). This PAS will be withdrawn upon publication of the

International Standard.

A list of all parts in the IEC 61076 series, published under the general title Connectors for

electrical and electronic equipment – Product requirements, can be found on the IEC website.

Future standards in this series will carry the new general title as cited above. Titles of existing

standards in this series will be updated at the time of the next edition.

This PAS shall remain valid for an initial maximum period of 2 years starting from the

publication date. The validity may be extended for a single period up to a maximum of

2 years, at the end of which it shall be published as another type of normative document, or

shall be withdrawn.

CONNECTORS FOR ELECTRICAL AND ELECTRONIC EQUIPMENT –
PRODUCT REQUIREMENTS –
Part 2-010: Circular connectors – Detail specification for push-pull
connectors with 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 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 to 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 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

1) 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
2) connectors for data and signal transmission with frequencies up to 500 MHz.

These connectors consist of both, fixed and free connectors, either rewireable or non-

rewireable, with M12 push-pull locking as explained above. Male connectors have round

contacts from Ø0,6 mm up to Ø1,5 mm. In addition, the push-pull mechanisms consist of

two different push-pull designs:

a) 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 two different types of male connectors. It has locking means for

both types on its outer surface.
NOTE 2 For design and dimensions, see 5.3.1 and 5.3.2.

b) An inner push-pull for female fixed connectors, where the locking means are placed onto

the inner cylindric surface of the housing.
NOTE 3 For design and dimensions. see 5.3.3.

The different codings provided by IEC 61076-2 and 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 IEC 61076-2.
