CONNECTORS FOR ELECTRONIC EQUIPMENT –
Part 3-104: Rectangular connectors –
Detail specification for 8-way, shielded free

with frequencies up to 600 MHz minimum
FOREWORD
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.
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 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 negotiate licences under reasonable and
non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the
holder of this patent right is registered with IEC. Information may be obtained from
The Siemon Company

Watertown, CT 06795-0400
USA
Attention is drawn to the possibility that some of the elements of this document 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.
International Standard IEC 61076-3-104 has been prepared by subcommittee 48B:
Connectors, of IEC technical committee 48: Electromechanical components and mechanical
structures for electronic equipment.
This standard cancels and replaces IEC/PAS 61076-3-104 published in 2002. This first edition
constitutes a technical revision.
The text of this standard is based on the following documents:
