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 61076-3-123 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:
FDIS Report on voting
48B/2742/FDIS 48B/2753/RVD
Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

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
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be

PRODUCT REQUIREMENTS –
Part 3-123: Rectangular connectors – Detail specification for hybrid
connectors for industrial environments, for power supply and fibre optic
data transmission, with push-pull locking

1 Scope
This part of IEC 61076 covers hybrid rectangular connectors with a 3 poles 16 A electric portion
for power supply and a duplex fibre optic connector type LC portion for data transmission. These
connectors consist of fixed and free connectors, either rewirable or non-rewirable (for both
portions) and use the rectangular push-pull housing described in IEC 61076-3-117 with
IP65/IP67 degree of protection, for harsh applications. The mating dimensions of such housings
allow fulfilling the performance class Category I according to IEC 61753-1-3 in regards to the
fibre optic portion of the connector with the exception of the operating temperature range which
is –25 °C/+70 °C.
The electric portion may have different rated insulation voltages. Male connectors have
3 electric round contacts Ø1,6 mm, with 16 A rated current.
NOTE Only the phase/neutral contacts are loaded upon current-carrying capacity test of 4.4 and 6.4.3 and electrical
load and temperature test in 7.2.2.6 (DP2) and 7.2.2.12 (KP5)
The fibre optic portion provides data transmission by using the common mating configurations
for all variants of the type LC duplex fibre optic connectors as defined in IEC 61754-20, for
dedicated fibre types and fibre termination technology covered therein.
The different codings provided by this document prevent the mating of accordingly coded male
or female connectors to any other similarly sized interfaces covered by other standards and the
cross-mating between the different codings provided by this document.
