Part 3-106: Rectangular connectors – Detail specification for protective
housings for use with 8-way shielded and unshielded connectors for
industrial environments incorporating the IEC 60603-7 series interface

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.
IEC 61076-3-106 has been prepared by subcommittee 48B: Electrical connectors, of IEC
technical committee 48: Electrical connectors and mechanical structures for electrical and
electronic equipment. It is an International Standard.
This second edition cancels and replaces the first edition published in 2006. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) improvement of drawings and addition of dimensions.

electrical and electronic equipment – Product requirements, can be found on the IEC website.
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 webstore.iec.ch in the data related to the
specific document. At this date, the document will be

INTRODUCTION
This document, originally issued in 2006 and including 10 variants, describes now 5 variants of
connector housing with different geometries (rectangular or circular) and locking systems
(locking lever, snap-in, bayonet coupling) suitable for all the connector interfaces of the
IEC 60603-7 series, either shielded or unshielded.
The purpose of this set of variants, now reduced to reflect their market relevance, is to provide
several competing ways to upgrade the degree of protection of the resulting data transmission
connectors, to IP65/IP67, mainly in view of their use in industrial environments, while
maintaining all the original performance of the housed IEC 60603-7 compliant connectors,
which can be of different source than these 5 variants of connector housings.
Each variant may be available on the market by multiple sources and based on different
materials (i.e. either metallic or thermoplastic insulating, particularly for the main part of the
housing, but also regarding the locking means) to suit the needs of various industrial
applications.
Some of these variants have been endorsed by other IEC technical committees and/or by
external consortia as the reference interface for specific applications.
Being the basic interface of series IEC 60603-7 a rectangular one, this standard document was
originally issued as a Part 106 detail product specifications under the IEC 61076-3 sectional
specification covering rectangular connectors for electrical and electronic equipment, although
half of the original variants described in this document (variants 01, 03, 08, 09 and 10), currently
only variant 01 is included in this document – own a circular connector interface, all the variants
having nonetheless in common the purpose to upgrade the IP degree of protection to IP65/IP67,
and the incorporated IEC 60603-7 series connector interface.
NOTE It is worthwhile to inform users of this document that further variants 11 through 14 referring this document
were successively published from 2007 to 2009 as IEC 61076-3-114 trough IEC 61076-3-117. Among these variants,
for which reference should be made to the relevant publication (see Bibliography), variants 11 and 12 have circular
geometry, while variants 13 and 14 have square (rectangular geometry).

Part 3-106: Rectangular connectors – Detail specification for protective
housings for use with 8-way shielded and unshielded connectors for
industrial environments incorporating the IEC 60603-7 series interface



1 Scope
This part of IEC 61076 constitutes a detail product specification for 8-way connectors for data
transmission with frequencies up to 600 MHz.
It covers protective housings for upgrading existing 8-way shielded and unshielded connectors
utilizing the interface described in the IEC 60603-7 series to IP65/IP67 rating according to
IEC 60529, for use in industrial environments.
The housings cover a variety of different locking mechanisms according to this document and
a variety of different mounting configurations and termination types which are detailed in the
IEC 60603-7 series.
Common mating configurations for all variants are defined in IEC 60603-7. The mating
dimensions for the housings under Clause 3 allow the mating conditions under IEC 60603-7 to
be fulfilled.
The fully assembled variants (connectors) described in this document incorporate fully
compliant IEC 60603-7 series fixed and free connectors.
