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 second edition cancels and replaces the first edition published in 2003 and its
Amendment 1 published in 2006. It is a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– the connector type M8 has been removed from IEC 61076-2-101 and has been
published in a separate IEC Standard under reference IEC 61076-2-104;
– the content of Amendment 1 is included in this International Standard;
– mounting thread changed from Pg to metric.

The text of this standard is based on the following documents:
FDIS Report on voting
48B/1893/FDIS 48B/1926/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition; or
• amended.
The contents of the corrigendum of March 2010 have been included in this copy.

Detail specification for M12 connectors with screw-locking

1 General information
Throughout this standard dimensions are in mm.
1.1 Scope
This International Standard describes circular connectors M12 typically used for industrial
process measurement and control. These connectors consist of fixed and free connectors
either rewireable or non-rewireable, with screw-locking. Male connectors have round contacts
∅ 0,6 mm, ∅ 0,76 mm, ∅ 0,8 mm and ∅ 1,0 mm.
The different codings prevent the mating of these coded male or female connectors to any
other interfaces and cross mating between the different codings.
NOTE M12 is the dimension of the thread of the screw locking mechanism of these circular connectors.
1.2 Recommended method of termination
The contact terminations shall be of the following types: screw, crimp, insulation piercing,
insulation displacement, press-in or solder.
1.2.1 Number of contacts or contact cavities
A-coding 2 to 12 contacts
B-coding 5 contacts
C-coding 3 to 6 contacts
