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 63171-7 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.
The text of this International Standard is based on the following documents:
Draft Report on voting
48B/3033/FDIS 48B/3044/RVD

Full information on the voting for its approval can be found in the report on voting indicated in
the above table.

electrical and electronic equipment, can be found on the IEC website.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in

INTRODUCTION
IEC 63171 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 the
complete specification regarding connectors described in this Part of the IEC 63171 series,
read this document in conjunction with IEC 63171.
A general overview about the connectors in this document is shown in Figure 1.

the inside cover.
DETAIL SPECIFICATION in accordance with IEC 61076-1 M12 screw locking or push-pull locking (or both)
Circular connectors, size 12, with 4 up to 7 ways
including PE or FE (according to coding) for
power and data transmission, either
– with M12 screw-locking mechanism (styles
with M12 in the name), or
– with a quick-locking push-pull mechanism
with a size derived from that (styles with P12
in the name), or
– with both mechanisms combined (styles with
C12 in the name).
Multiple mating interfaces, each associated with
a coding referred to as "type I" through "type
VII", differing by power transmission capabilities
and intents.
2 ways + additional shield pin (to be connected
to the cable sheath) support balanced differential
data transmission with frequencies up to

600 MHz, Category B as per IEC 63171.
Free cable connectors:
– male or female,
– straight connectors,
– rewireable or non-rewireable.
Fixed connectors:

CONNECTORS FOR ELECTRICAL AND ELECTRONIC EQUIPMENT –

Part 7: Detail specification for up to 7 ways including PE or FE
(data/power) and shield pin, free and fixed circular connectors for
balanced single-pair data transmission with current-carrying capacity –
Mechanical mating information, pin assignment and additional
requirements for type 7



1 Scope
This part of IEC 63171 covers shielded free and fixed circular connectors with 4 ways up to
7 ways for power and data transmission and specifies the common dimensions, mechanical,
electrical and transmission characteristics and environmental requirements as well as test
specifications respectively.
The connectors described in this document are either equipped with an M12 screw-locking
mechanism (styles with M12 in the name) or a quick-locking push-pull mechanism with a size
derived from that (styles with P12 in the name) or both mechanisms combined (styles with C12
in the name). For the sake of simplicity, the connectors' size is denoted as "size 12" in this
document.
This document provides multiple mating interfaces each of which is associated with a coding
preventing the mating of incompatible male and female connectors. These codings are referred
to as "Type x", where "x" is represented by a Roman numeral.
For all codings, two ways and the additional shield pin, which is intended to be connected to
the cable screen, support differential data transmission with frequencies up to 600 MHz by
meeting the requirements of Category B, as defined in IEC 63171.
NOTE 1 Connecting the shield pin to the cable sheath is also required for data transmission with 20 MHz
(IEC 63171, Category A).
NOTE 2 The connectors are intended to be used for single-pair Ethernet (SPE) according to the following IEEE
Standards: 10BASE-T1 (IEEE 802.3cg), 100BASE-T1 (IEEE 802.3bw), 1000BASE-T1 (IEEE 802.3bp).
NOTE 3 Power over Data line (PoDL) power supply according to IEEE 802.3bu can be optionally used for the two
ways intended for data transmission, even in addition to the power supply provided through the dedicated power
ways.
The individual codings differ by their power transmission capabilities and intents. The additional
ways provide for DC power transmission with up to 63 V/16 A and 600 V/16 A or AC power
transmission with rated voltage and rated current up to 600 V/16 A (single-phase) or 480 V/8 A
(three-phase). See Table 11 and Table 12 for the voltage and current ratings, and Table 5 for
the pin assignments for the individual codings.
Some codings feature a PE pin for safety purposes.
The PE pin needs to be connected to all accessible metal parts.
