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 61076-8-100 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 standard is based on the following documents:

stated by the manufacturer.
4.7 Marking
The marking of the connector and the package shall be in accordance with 2.7 of
IEC 61076-1:2006.
5 Dimensional information
5.1 General
Dimensions are given in millimetres. Drawings are shown in the first angle projection. The
shape of the connectors may deviate from those given in the following drawings as long as
the specified dimensions are not influenced.
For safety aspects IEC 61984 shall be considered unless otherwise specified.
Missing dimensions shall be chosen according to the common characteristics and intended
use.
5.2 Isometric view and common features
Figure 1 and Figure 2 are isometric views of free and fixed connectors.

5.2.1 Isometric view of free connectors

Figure 1 – 2-pole and 3-pole free connectors
5.2.2 Isometric view of fixed connectors

5.3 Engagement (mating) information
5.3.1 General
5.3.1.1 Engagement (mating) direction
Not applicable.
5.3.1.2 Contact levels and sequencing
Power contacts shall be engaged prior to signal contacts in the mating process of connectors.
Power contacts shall be withdrawn posterior to signal contacts in the separating process of
connectors. In other words, signal contacts shall be of the FBLM (first break last make) type.
5.3.2 Perpendicular to the engaging (mating) direction
Not applicable.
5.3.3 Inclination
Not applicable.
5.4 Fixed connectors

Figure 5 – Fixed connector codings
The fixed connector housing may have four different combinations of coding keys in its
contour, as shown in Figure 5 and dimensions in Table 4, using three integral coding keys on
the short sides of the housing that, in combination with the corresponding three keyways in
the contour of the mating free connector hood, act as coding device, i.e. prevent the mating or
the engagement of two connectors of the same family which should not mate in an application.
