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:

– 6 – 61076-2-101 © IEC:2012
specified in IEC 61076-2-101 Ed. 2 are further applicable for the added interface
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.
The text of this standard is based on the following documents:
FDIS Report on voting
48B/2279/FDIS 48B/2288/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.
A list of all parts of IEC 61076 series, under the general title Connectors for electronic
equipment – Product requirements, can be found on the IEC website.
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 stability 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.

Detail specification for M12 connectors with screw-locking

1 Scope
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.
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.

3.1 Terms and definitions
For the purposes of this document, terms and definitions from IEC 60050-581 as well as the
following apply.
3.1.1
mounting orientation
circular mounting position of the connector in relation to the polarization of the mating
interface
NOTE Where the free connector has an angled cable entry (as opposed to an in-line cable entry), the angle
between the cable entry direction and the polarization keyway should be specified.
3.1.2
glass to metal seal
a form of construction whereby the connector contacts are housed in a glass insert which is
inside a metal connector shell so as to form a connector with a hermetic seal which may be
used to isolate differing environments
3.1.3
matched glass to metal seal
a form of construction whereby the thermal expansion characteristics of the glass, the metallic
contacts, and the connector shell are similar and the seal between the glass and the metal is
formed by a chemical bond
3.1.4
compression glass to metal seal
a form of construction whereby due to the its higher coefficient of expansion the shell
contracts around the glass during the solidification phase of manufacture applying a
compression force to the glass insert so as to form a seal
3.2 Recommended method of termination
3.2.1 General
The contact terminations shall be of the following types: screw, crimp, insulation piercing,
insulation displacement, press-in or solder. For the male connectors having a glass to metal
seal the recommended contact terminations are crimp, eyelet, solder, PCB and rounded.
NOTE 1 eyelet – the termination end is flattened and pierced with a hole to provide both mechanical retention of
the wire as well as solder attachment.
