Part 6: Detail specification for 2-way and 4-way (data/power),
shielded, free and fixed connectors for power and data
transmission with frequencies up to 600 MHz

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.
This International Standard IEC 63171-6 has been prepared by subcommittee 48B: Electrical
connectors, of IEC technical committee 48: Electrical connectors and mechanical structures for
electrical and electronic equipment.
This second edition cancels and replaces the first edition published in 2020. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Mating conditions changed, see Figure 2, Figure 4, Figure 13, Figure 15, Figure 19 and
Figure 21.
b) Voltage proof requirement added, 2 250 V DC, see 5.7.2.
c) Mechanical shock requirement added, see 5.7.6 (the requirement itself already was
specified indirectly by Ed1 due to the specification of the test EP3 of Table 14 which is still
identical to Ed1).
– 6 – IEC 63171-6:2021 © IEC 2021
d) Styles added, 6P-M8CI and 6J-M8CI, see Table 1.
The text of this International Standard is based on the following documents:

For the purposes of this document, the terms and definitions given in IEC 60050-581,
IEC 61076-1, IEC 61076-3 and IEC 60512-1 apply.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:

• ISO Online browsing platform: available at http://www.iso.org/obp

4 Common features and typical connector pair
4.1 Systems of levels – Compatibility levels
4.1.1 Performance level
Connectors according to this document are classified by mating performance level (MPL). See
5.7.1 for details.
4.1.2 Compatibility levels
Compatibility levels are according to IEC 61076-1
a) Intermateability
Intermateability as defined in Clause B.3 of IEC 61076-1:2006 standardizes only dimensions
of electrical and mechanical interfaces. Intermateability shall be 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.
b) Interoperability
Interoperability as defined in Clause B.5 of IEC 61076-1:2006 shall be assured by
compliance with the specified interface dimensions and by compliance with the requirements
in 5.2 through 5.7 proven by the respective testing sequences in Clause 6.
4.2 Classification into climatic categories
See 5.2.
4.3 Clearance and creepage distances
See 5.3.1.
4.4 Current carrying capacity
See 5.3.4
4.5 Marking
The marking of the connector and the packaging shall be in accordance with 2.7 of
IEC 61076-12006.
4.6 Dimensional information
4.6.1 General
Drawings are shown in the first angle projection. The shape of connectors may deviate from
those shapes given in the following figures as long as the specified dimensions are not
influenced. Coordination dimensions are dimensions without tolerances which indicate the
boundary or centre-line references in order to allow for (modular) arrangement.
4.6.2 Isometric view and common features – Connector styles

The terms PLUG and JACK are used only for easier reading since they are widely used.
The designation “size 8” and “size 12” indicates roughly the diameter of the jack in millimetres.

5 Characteristics
5.1 General
Compliance to the test schedules shall ensure the reliability of all performance parameters,
over the range of operating climatic conditions given in this document. Stable and compliant
contact resistance is a good indication of the stability of transmission performance.
NOTE With respect to the environmental rating scheme defined by ISO/IEC 11801-1:2017, 6.2.2 (MICE classes)
components according to this document are of higher rating than M1, mechanical. The rating with respect to ingress,
chemical and electromagnetical follows the scheme of IEC 61984 and IEC 61076 series and is not comparable to the
MICE classification of ISO/IEC 11801-1.
5.2 Classification into climatic category
The lowest and highest temperatures and the duration of the damp-heat steady-state test
should be selected from the preferred values st
