Part 3-122: Detail specification for rugged 8-way,
shielded, free and fixed connectors

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.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC PAS 61076-3-122 has been processed by subcommittee 48B: Electrical connectors, of
IEC technical committee 48: Electrical connectors and mechanical structures for electrical and
electronic equipment.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document
Draft PAS Report on voting
48B/2401/PAS 48B/2408/RVD
Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned may transform it into an International Standard.
This PAS shall remain valid for an initial maximum period of 3 years starting from the
publication date. The validity may be extended for a single period up to a maximum of 3 years,
at the end of which it shall be published as another type of normative document, or shall be
withdrawn.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

Part 3-122: Detail specification for rugged 8-way,
shielded, free and fixed connectors

1 Scope
This part of IEC 61076-3 covers 8-way unshielded free and fixed connectors, and is intended
to specify the common dimensions, mechanical, electrical and environmental characteristics
and tests for the family of IEC 61076-3 connectors.
These connectors are intermateable and interoperable with other IEC 61076-3 series
connectors.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-581,
IEC 61076-1, IEC 60512-1, and the following apply.
3.1
intermateability
intermateability (level 2 of IEC 61076-1:2006) is 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
3.2
interoperability
interoperability of different IEC 61076-3 connectors is ensured by compliance with the
specified interface dimensions

4.2 Mating information
4.2.1 General
Dimensions are given in millimetres. Drawings are shown in third-angle projection. The shape
of connectors may deviate from those given in Figures 1 to 6 as long as the dimensions
specified are not changed.
