Overview

EN IEC 63171-1:2020 (IEC 63171-1:2020) defines detailed specifications for two-way, shielded or unshielded, free (plug) and fixed (receptacle) connectors in the Type 1 copper LC style. The standard covers mechanical mating information, pin assignment and additional requirements for connectors used for data transmission up to 600 MHz and with a current-carrying capacity up to 2.0 A at 60 °C. It specifies common dimensions, mechanical, electrical, signal‑integrity, environmental and reliability characteristics and the corresponding tests.

Key topics and technical requirements

• Mechanical mating information: dimensional and mating specifications for free and fixed connector parts, insertion/withdrawal forces and coupling device effectiveness.
• Pin assignment: standardized contact layout for Type 1 LC style two‑pole connectors to ensure interoperability.
• Electrical characteristics: contact resistance (interface), insulation resistance, voltage proof and current–temperature derating up to specified limits.
• Transmission and signal‑integrity parameters: requirements and test methods for insertion loss (IL), return loss (RL), transverse conversion loss (TCL), transfer conversion transfer loss (TCTL), and power-sum alien crosstalk metrics (PS ANEXT / PS AFEXT).
• Shield performance (for shielded variants): transfer impedance and coupling attenuation test requirements to validate EMC/screening effectiveness.
• Environmental and mechanical testing: climatic categories, vibration, mechanical operation endurance, and specific test schedules (basic and full) organized into test groups (climatic, mechanical, vibration, electrical load, electrical transmission, transfer impedance/coupling attenuation).
• Referenced test methods and normative standards: includes IEC 60512 series (connector tests), IEC 60068 (environmental), IEC 60664 (insulation coordination), IEC 62153 (EMC/transfer impedance), and ISO/IEC 11801‑1 (cabling context).

Applications and who uses this standard

• Connector manufacturers and component designers developing LC-style two‑pole copper connectors for data applications.
• Cable system designers and OEMs who need assured interoperability, mechanical compatibility and signal‑integrity performance.
• Test laboratories and quality teams implementing the prescribed test schedules and measurements.
• System integrators and product engineers in building automation, industrial communications and low‑power data links where compact two‑pole connectors are required with controlled EMC and transmission behavior.

Related standards

• IEC 60512 series (tests and measurements for connectors)
• IEC 60068 (environmental testing)
• IEC 60664-1 (insulation coordination)
• IEC 62153-4-12 / 4-15 (transfer impedance and coupling attenuation)
• ISO/IEC 11801-1 (generic cabling context)

EN IEC 63171-1:2020 is essential when specifying or validating two‑way copper LC style connectors for reliable data transmission, mechanical interoperability and verified EMC/signal integrity 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.
International Standard IEC 63171-1 has been prepared by subcommittee 48B: Electrical
connectors of IEC technical committee 48: Electrical connectors and mechanical structures for
electrical and electronic equipment.
The text of this International Standard is based on the following documents:

INTRODUCTION
The International Electrotechnical Commission (IEC) draws attention to the fact that it is
claimed that compliance with this document may involve the use of a patent concerning
contact mating surface dimensions given in 5.1.
The IEC takes no position concerning the evidence, validity and scope of this patent right.
The holder of the patent right on contact mating surface dimensions in 5.1 has assured the
IEC that they are willing to give free licences to applicants throughout the world. In this
respect, the statement of the holder of this patent right is registered with the IEC
Information may be obtained from:

Attention is drawn to the possibility that some of the elements of this International Standard
may be the subject of patent rights other than those identified above. IEC shall not be held
responsible for identifying any or all such patent rights.
ISO (www.iso.org/patents) and IEC (http://patents.iec.ch) maintain on-line data bases of
patents relevant to their standards. Users are encouraged to consult the data bases for the
most up to date information concerning patents.
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
complete specification regarding a component of a higher number document the base
numbered documents should be considered as well. The following diagram (see Figure 1)
shows the interrelation of the documents:
