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.
This International Standard IEC 61076-3-124 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:

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.
The committee has decided that the contents of this document will remain unchanged until the

Part 3-124: Rectangular connectors – Detail specification for 10-way,
shielded, free and fixed connectors for I/O and data transmission
with frequencies up to 500 MHz

1 Scope
This part of IEC 61076 covers 10-way, shielded, free and fixed rectangular connectors for data
transmission with frequencies up to 500 MHz and specifies the common dimensions,
mechanical, electrical and transmission characteristics and environmental requirements as well
as test specifications respectively.
Connectors covered in this document are provided in three codings that differ only for the
position of the polarization key and keyway, in view of their differently intended use:
• Connectors Type A and C are intended for 10/100 Mbit/s as well as for 1/ 2,5 / 5 /10 Gbit/s
Ethernet communication.
• Connectors Type B are intended for all other non-Ethernet applications such as signalling,
serial or other industrial bus communication systems.
A-coding: The 45° cut corner used as polarization key and keyway system is located on the
lower left corner of the male fixed connector (viewed from mating face) (Figures 5a, 5b).
B-coding: The 45° cut corner is located on the upper left corner of the male fixed connector
(Figures 5c, 5d).
C-coding: There are two 45° corners located at the upper left and lower left corner
(Figures 5e, 5f).
In this document, the three codings, A, B, and C are designated as “Type A”, “Type B” and
“Type C”.

4 Technical information
4.1 Systems of levels – Compatibility levels, according to IEC 61076-1:2006
4.1.1 Performance level
Connectors according to this document are classified by mating performance level (MPL).
See 6.5.1, Table 12 for details.
4.1.2 Compatibility levels according to IEC 61076
a) Intermateability
Intermateability (level 2 of IEC 61076-1:2006) standardizes only dimensions of electrical and
mechanical interfaces. Intermateability shall be ensured by application of the “Go” and “No-Go”
gauge requirements in the standards that may be referenced, and adherence to the dimensional
requirements within.
b) Interoperability
Interoperability of different connectors shall be assured by compliance with the specified
interface dimensions and by compliance with the relevant signal integrity test group FP.
4.2 Classification into climatic categories
See 6.3.
IEC 61076-3-124:2019 © IEC 2019 – 11 –
4.3 Clearance and creepage distances
See 6.4.2.
4.4 Current carrying capacity
See 6.4.4.
4.5 Marking
The marking of the connector and the packaging 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 third angle projection. The
shape of connectors may deviate from those shapes given in the following figures as long as
the specified dimensions are not influenced (see Figure 1 to Figure 8 and Table 1 to Table 9).
Coordination dimensions are dimensions without tolerances which indicate the boundary or
centre-line references in order to allow for (modular) arrangement.
