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 61076-3-110 has been prepared by subcommittee 48B:
Connectors, of IEC technical committee 48: Electromechanical components and mechanical
structures for electronic equipment.
This second edition cancels and replaces the first edition, issued in 2007, and constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– changes in 4.5 regarding electrical transmission performance i.e. return loss, among other
specific changes, in compliance to the requirements of ISO/IEC 11801,
– updated text and format to be consistent with the referenced standards,
– removal of duplication of requirements in the IEC 60603-7 standard series,

INTRODUCTION
This detail specification describes connectors according to the IEC 61076-3 series connector
requirements.
This detail specification describes connectors that are similar to and compatible with
IEC 60603-7 series connectors.
The IEC 61076-3-110 free connector can be used in data communication cabling systems with
the IEC 60603-7-7 and IEC 60603-7-71 fixed connector.
The IEC 61076-3-110 connector includes up to 12 contacts, including up to 8 contacts
(1,2,3,4,5,6,7,8) that are similar to a standard IEC 60603-7 series connector. In addition, the
IEC 61076-3-110 connector includes up to 4 additional contacts (6’,3’,4’,5’) located on the
opposite side from the original contacts’ positions of a basic IEC 60603-7 series connector.
For use in high speed communications cabling systems, IEC 60603-7-7 and IEC 60603-7-71
fixed connectors include a switch or other means to engage these two different sets of four
contacts to enable backward compatibility for transmission performance. In this application
the IEC 61076-3-110 free connector simply uses 8 contacts (1,2,3’,4’,5’,6’,7,8) and no switch.
The IEC 61076-3-110 fixed connector includes a board mounted style in addition to the cable
mounted style.
The complete requirements for the connectors described herein correspond to this detail
specification and the current issues of IEC 61076-3 and IEC 60603-7 series, which are
referenced herein accordingly.

3.3 Intermateability
Intermateability is ensured by applying the “GO” and “NO-GO” gauge requirements herein,
and adherence to dimensional requirements herein.
3.4 Interoperability
Interoperability of different IEC 61076-3-110 connectors is ensured by compliance with all
transmission requirements when the connector is mated with a free connector as described in
IEC 60512-28-100.
These connectors are interoperable with IEC 60603-7-7 and IEC 60603-7-71 series
connectors.
NOTE (transmission performance categories) In this IEC standard, the term “category”, when used in reference to
transmission performance, refers to those categories defined by ISO/IEC 11801.
