Part 3-104: Detail specification for 8-way, shielded free and fixed
connectors for data transmissions with frequencies up to 1 000 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 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.
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 connectors given in 3.2.2 and 3.2.4.

4 Terminations
4.1 General
A connector may include multiple terminations between the cable termination and the
separable contact interface. These may include press-in (compliant pin) connections of jack
springs into PCBs, for example. All terminations shall meet the relevant termination
requirements.
If a type of solderless termination is used which is not covered by any IEC 60352 series
specification, the supplier shall assure its reliability by performing similar tests, and
demonstrating a similar level of performance, to those in IEC 60352.
Free connectors are intended to be terminated to cable to provide connector and cable
assemblies. The connector type designation provides basic terminations concerning the type
of conductor (tinsel, stranded, solid) to which the conductor may be applied, and the type of
connection used (solder, insulation displacement, etc.). Specific details concerning wire
gauge size, type and thickness of conductor insulation, size and shape of cordage or cable
jacket, etc., are not intended to be part of this specification. Minor variations in a free
connector’s interior details to accommodate differing wire gauge sizes, outer jackets, etc., do
not require the generation of new free connector specifications.
If the connector is able to be used with multiple cable types, the manufacturer shall assure
that all connection points comply with the relevant IEC standards with each of the cable types.
4.2 Referenced termination types
4.2.1 General
If a type of solderless termination is used, which is covered by a IEC 60352 series
specification, the supplier shall assure its reliability by performing tests and demonstrating a
level of performance, according to the IEC 60352 series.
4.2.2 Insulation displacement terminations
Shall conform to IEC 60352-3 or IEC 60352-4.
4.2.3 Crimp terminations
Shall conform to IEC 60352-2.
4.2.4 Insulation piercing terminations
Shall conform to IEC 60352-6.
4.2.5 Compliant pin (press-in)
Shall conform to IEC 60352-5.
4.2.6 Spring clamp terminations
Shall conform to IEC 60352-7.
4.2.7 Non-referenced termination types
If a type of termination is used which is not covered by any IEC 60352 series specification,
the supplier shall assure its reliability by performing similar tests, and demonstrating a similar
level of performance, to those covered by IEC 60352 series.

61076-3-104 © IEC:2006 – 27 –
4.2.8 Solder terminations
Solder terminations are not covered in the IEC 60352 series and are allowed.
4.3 Accessories
Accessories are not specified.
4.4 Mounting information for fixed connectors
4.4.1 General
Fixed connector mounting information is not specified.
4.4.2 Hole pattern on printed boards
Fixed connector printed board mounting is not specified.
4.4.3 Mounting on panels
Fixed connector mounting on panels is not specified.
4.5 Mounting information for free connectors
Mounting information for free connectors onto cables is not specified.
5 Gauges
5.1 General
Gauges shall be made according to the following requirements:
Material: tool steel, hardened.
√ = Surface roughness, according to ISO 1302.
Ra = 0,25mm max. (10min max.).
A 0,01 mm (0,000 4 in) wear tolerance shall be applied.
Clearance shall be provided for connector contacts.
Annex A has additional information about using the gauges.
