(Main)Connectors for electrical and electronic equipment - Part 5: Detail specification for 2-way M8 and M12 circular connectors, shielded or unshielded, free and fixed - Mechanical mating information, pin assignment and additional requirements for Type 5 (IEC 63171-5:2022)
Connectors for electrical and electronic equipment - Part 5: Detail specification for 2-way M8 and M12 circular connectors, shielded or unshielded, free and fixed - Mechanical mating information, pin assignment and additional requirements for Type 5 (IEC 63171-5:2022)
This part of IEC 63171 describes shielded or unshielded circular connectors with 2 ways and M8 or M12 Styles, typically used for data transmission up to 600 MHz and with current carrying capacity up to 4 A, for use in areas with harsh environmental conditions. These connectors consist of fixed and free connectors either rewirable or non-rewirable. Male connectors have square cross- section contacts, for data and power transmission.
M12 describes the dimensions of the styles and thread of the screw-locking mechanism according IEC 61076-2-101 of this size of circular connectors. M8 describes the dimensions of the styles and thread of the screw-locking mechanism according IEC 61076-2-104. The use of alternative locking mechanisms according to IEC 61076-2-010 or IEC 61076-2-011 are possible.
The coding provided by this standard prevents the mating of accordingly coded male or female connectors to other similarly sized interfaces covered by this or other standards.
These Type 5 connectors are interoperable with Type 2 connectors according IEC 63171-2, except the locking and sealing system provided by the outer shell.
The shielded and unshielded connectors are interoperable for their internal transmission performance and can be exchanged. The shielded version has improved EMC and coupling properties.
This part of IEC 63171 covers Type 5 connectors. Each part of this series has the associated type number equal to the number of the part in the series. All connectors in the IEC 63171 series are deemed to provide the same functions as defined in IEC 63171:2021, using different mechanical interfaces.

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 63171-5 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.

129 FOREWORD
130 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
131 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
132 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
133 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
134 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
135 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
136 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
137 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
138 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
139 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
140 consensus of opinion on the relevant subjects since each technical committee has representation from all
141 interested IEC National Committees.
142 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
143 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
144 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
145 misinterpretation by any end user.
146 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
147 transparently to the maximum extent possible in their national and regional publications. Any divergence between
148 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
149 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
150 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
151 services carried out by independent certification bodies.
152 6) All users should ensure that they have the latest edition of this publication.
153 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
154 members of its technical committees and IEC National Committees for any personal injury, property damage or
155 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
156 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
157 Publications.
158 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
159 indispensable for the correct application of this publication.
160 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
161 rights. IEC shall not be held responsible for identifying any or all such patent rights.
162 International Standard IEC 63171-5 has been prepared by subcommittee 48B: Electrical
163 connectors, of IEC technical committee 48: Electrical connectors and mechanical structures for
164 electrical and electronic equipment
165 The text of this standard is based on the following documents:

181 INTRODUCTION
182 IEC 63171 is the base specification of the whole series. Subsequent specifications do not
183 duplicate information given in the base document, but list only additional requirements. For
184 complete specification regarding a component of a higher number document all lower numbered
185 documents must be considered as well. The following diagram shows the interrelation of the
186 documents:

197 Part 5: Detail specification for 2-way M8 and M12 circular connectors,
198 shielded or unshielded, free and fixed – Mechanical mating information,
199 pin assignment and additional requirements for Type 5
200 1 Scope
201 This part of IEC 63171 describes shielded or unshielded circular connectors with 2 ways and
202 M8 or M12 Styles, typically used for data transmission up to 600 MHz and with current-
203 carrying capacity up to 4 A, for use in areas with harsh environmental conditions. These
204 connectors consist of fixed and free connectors either rewirable or non-rewirable. Male
205 connectors have square cross- section contacts, for data and power transmission.
206 M12 describes the dimensions of the styles and thread of the screw-locking mechanism
207 according IEC 61076-2-101 of this size of circular connectors. M8 describes the dimensions
208 of the styles and thread of the screw-locking mechanism according IEC 61076-2-104. The use
209 of alternative locking mechanisms according to IEC 61076-2-010 or IEC 61076-2-011 are
210 possible.
211 The coding provided by this standard prevents the mating of accordingly coded male or female
212 connectors to other similarly sized interfaces covered by this or other standards.
213 These Type 5 connectors are interoperable with Type 2 connectors according IEC 63171-2,
214 except the locking and sealing system provided by the outer shell.
215 The shielded and unshielded connectors are interoperable for their internal transmission
216 performance and can be exchanged. The shielded version has improved EMC and coupling
217 properties.
218 This part of IEC 63171 covers Type 5 connectors. Each part of this series has the associated
219 type number equal to the number of the part in the series. All connectors in the IEC 63171
220 series are deemed to provide the same functions as defined in IEC 63171:2021, using
221 different mechanical interfaces.
222 2 Normative references
223 In addition to the normative references in IEC 63171:2021, the following documents are
