CONNECTORS FOR ELECTRONIC EQUIPMENT –

Part 3-104: Detail specification for 8-way, shielded free

and fixed connectors for data transmissions

with frequencies up to 600 MHz minimum

FOREWORD
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC-PAS 61076-3-104 has been processed by subcommittee 48B: Connectors, of IEC
technical committee 48: Electromechanical components and mechanical structures for
electronic equipment.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document:
Draft PAS Report on voting
48B/1167/PAS 48B/1215A/RVD
Following publication of this PAS, the technical committee or subcommittee concerned will
investigate the possibility of transforming the PAS into an International Standard.
The International Electrotechnical Commission (IEC) draws attention to the fact that it is
claimed that compliance with this PAS may involve the use of patents concerning 8-way,
shielded free and fixed connectors for data transmissions with frequencies up to 600 MHz
minimum.
The IEC takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured the IEC that he is willing to give free licences with
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:
The Siemon Company
Siemon Business Park
76 Westbury Park Road
Watertown, CT 06795-0400
USA
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.
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.

3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National

Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International

Standards transparently to the maximum extent possible in their national and regional standards. Any

divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with one of its standards.

1 General
1.1 Scope
This part of IEC 61076 establishes uniform specifications, type testing requirements and
quality assessment procedures for 8 ways connectors, with up to 4 pairs, for frequencies up to
600 MHz minimum, and intended to be used at different locations within cabling for ICT, home
entertainment and multimedia. It contains a choice of all test methods and sequences,
severity and preferred values for dimensions and characteristics.
1.2 Normative references
The following normative documents contain provisions that, through reference in this text,
constitute provisions of this part of IEC 61076. At the time of publication, the editions
indicated were valid. All normative documents are subject to revision, and parties to
agreements based on this part of IEC 61076 are encouraged to investigate the possibility of
applying the most recent editions of the normative documents listed below. Members of IEC
and ISO maintain registers of currently valid International Standards.

2 Marking Information
2.1 IEC type designation
Connectors, connector bodies and connectors with pre-inserted contacts according to this
standard shall be designated by the following system.
Connectors conforming to this standard shall be identified by the following indications and in
the order given:
The letters “IEC”.
The number denoting this sectional specification.
The number of the detail specification (without dashes), being nine characters (e.g.
610764100).
A letter denoting the style of the connector (the system shall be specified in the detail
specification
2.2 Marking
Each connector and its associated package shall be marked in accordance with the
requirements specified in 2.6 of IEC 61076-1.
2.3 Groups of Related Connectors
Groups of connectors within a subfamily having common features. Typical examples are
same type and range but different style. A group of related connectors is covered by a single
detail specification.
• Type: Connectors within a particular subfamily such as a multicontact connector with one,
two or four pairs.
• Range: The housing (shell) sizes and contacts arrangements within a type. For example
a housing containing one, two or four pairs.
• Style: A particular connector within a type, for example fixed panel, PCB or free connector.
• Variant: Variations within a type, style or range.
2.4 Interchangeability Level
These connectors shall be fully interchangeable and intermateable. The mechanical and
electrical characteristics shall be met whatever is the source of the connector. Moreover it is
desirable that the mechanical and electrical compatibility with lower performance connecting
hardware as defined in ISO/IEC 11801 and IEC 60603-7 is ensured when connected to
this connector.
This can be achieved through the use of an adapter cord. Elements of connecting hardware,
e.g. plugs, sockets that terminate more than one cable are permitted.
The plug/socket interface may be constructed so as to permit the use of multiple modules
e.g. 2 × 2 pairs or 4 × 1 pair plugs mated directly with a single 4 pairs socket.

4 Characteristics
4.1 General
Compliance to the test schedules is intended to ensure the reliability of all performance parameters,
including transmission parameters. Stable and compliant contact resistance is a good indication of the
stability of transmission performance.
4.2 Terminology
The terminology used in and applicable to this specification is stated in 2.1 of IEC 61076-1.
IEC 60512-1 also contains applicable terms.
4.3 Classification into Climatic Categories
The lower and upper temperatures and the duration of the damp heat, steady state test
should, unless otherwise impractical, be selected from the preferred values stated in 2.2 of

IEC 61076-1. The connectors are classified into climatic categories in accordance with the

general rules given in IEC 60068-1. The following preferred temperature range and severity of

the damp heat steady state test has been selected.

4.4 Creepage and Clearance Distances
The permissible operating voltages depend on the application and on the applicable or
specified safety requirements.
Insulation co-ordination is not required for this connector; therefore, the creepage and
clearance distances in IEC 60664-1 are reduced and covered by overall performance
requirements.
Therefore, the creepage and clearance distances are given as operating characteristics of
mated connectors.
In practice, reductions in creepage or clearance distances may occur due to the conductive
pattern of the printed board or the wiring used, and shall duly be taken into account.

4.5 Electrical Characteristics

4.5.1 Current carrying capacity
The current carrying capacity of connectors in accordance with the requirements of 2.4 of
IEC 61076-1 shall be greater or equal to 1 A at 20 °C.
