Connectors for electronic equipment - Product requirements - Part 3-104: Detail specification for 8-way, shielded free and fixed connectors for data transmissions with frequencies up to 2000 MHz (IEC 61076-3-104:2017)

IEC 61076-3-104:2017(E) establishes uniform specifications, type testing requirements for 8 way, shielded free and fixed connectors for data transmissions with frequencies up to 2 000 MHz, and used as category 7A connectors in class FA cabling systems specified in ISO/IEC 11801-1. It contains all test methods and sequences, severity and preferred values for dimensions and characteristics.
This third edition of IEC 61076-3-104 cancels and replaces the second edition, published in 2006, and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- the title has been changed to incorporate transmissions with frequencies up to 2 000 MHz;
- the drawings of some styles have been corrected for clarification;
- Figures 23 and 24 have been updated;
- Figure 3 has been updated to include reference dimensions and dimensional format changes;
- the dimensions of Figure 7 have been updated;
- the type designation and ordering information has been removed for consistency with the most updated sectional specification;
- the test schedule was updated to include appropriate IEC 60512 Test Nos;
- the electrical performance requirements have been revised for 2 GHz level and interchangeability information has been added for performance categories.

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
