CONNECTORS FOR ELECTRONIC EQUIPMENT –

Part 7-1: Detail specification for 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60603-7-1 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 published in 2002. This edition
constitutes a technical revision.
This edition included the following significant technical changes with respect to the previous
edition:
1) The basic connector dimensions were removed from the edition 1 standard and referenced
to IEC 60603-7.
2) Several other subclauses were removed (e.g. 4.1, 5, 6.1, 6.2) from the edition 1 standard
and referenced to IEC 60603-7.
3) The electrical characteristics, subclause 6.4, was revised.
4) The test schedules were revised.

INTRODUCTION
Applications have emerged which require the use of the interface described in IEC 60603-7 with
certain performance specifications at higher frequencies. Therefore, a series of detail
specifications have been issued the past few years in support of these new applications. In
order to improve readability and ease of maintenance, IEC Subcommittee 48B (SC 48B)
decided to rearrange and restructure these existing documents.
This part of IEC 60603-7 contains only the necessary information regarding the shield of the
connection and is designed to be used as a base document for all shielded connectors in the
IEC 60603-7 series.
For further information regarding the IEC 60603-7 style connection, reference to the
unshielded base document IEC 60603-7 is made.
IEC 60603-7 is the base specification of the whole series. Subsequent specifications do not
duplicate information given in the base document, but list only additional requirements. For a
complete specification regarding a component of a higher number document, all lower
numbered documents are also to be considered.
The following illustration shows the IEC 60603-7 document structure:

When this dimension is less than 6,85 mm and the free connector is mated with a IEC 60603-7-7 fixed connector,
utilising switch option 1, there is a possibility that signal conductors 3,4,5,6 of the fixed connector may make contact
with the shield of this free connector.
4 Cable terminations and internal connections – Fixed and free connectors
4.1 Internal connections
Internal connections of the shield shall conform to Clause 4 of IEC 60603-7.
4.2 Cable termination
The connector shall be compliant with the full test schedule in 7.7.2 for all possible variations
of terminations, for example each cable screen construction type the connector is intended to
be used for.
5 Gauges
There are no shield specific gauges for IEC 60603-7-1 connectors. For overall dimensions,
the gauges as defined by Clause 5 of IEC 60603-7 shall apply.
6 Characteristics
6.1 General
Compliance to the test schedules is intended to ensure the reliability of all performance
parameters, over the range of operating climatic conditions. Stable and compliant contact
resistance is a good indication of the stability of shield performance.
The characteristics of the signal contacts of connectors according IEC 60603-7-1 shall
conform to all relevant requirements specified by IEC 60603-7.
6.2 Pin and pair grouping assignment
The pin and pair grouping assignment of 6.2 of IEC 60603-7 applies.
6.3 Classification into climatic category
Connectors according to IEC 60603-7-1 are classified in the same climatic categories as
defined by IEC 60603-7.

6.4 Electrical characteristics
6.4.1 Creepage and clearance distances
Insulation coordination is not required for this connector; therefore, the creepage and
clearance distances in IEC 60664-1 are reduced and covered by overall performance
requirements.
Therefore, the creepage and clearance distances are given as operating characteristics of
mated connectors.
In practice, reductions in creepage or clearance distances may occur due to the conductive
pattern of the printed board or the wiring used, and shall duly be taken into account.
