IEC 60603-7-4:2010 pdf – Connectors for electronic equipment – Partie 7-4: Detail specification for 8-way, unshielded, free and fixed connectors,for data transmission with frequencies up to 250 MHz.
This pad of IEC 60603 covers 8-way, unshielded, free and fixed connectors, references dimensional, mechanical, electrical and environmental characteristics and tests in IEC 60603-
7. and specifies electrical transmission requirements for frequencies up to 250 MHz. These connectors are typically used as category 6 connectors in class E cabling systems specified in
ISOIIEC 11801.
These connectors are intermateable and interoperable with other IEC 60603.1 series connectors as defined in Clause 2 of IEC 60603-7.
These connectors are backward compatible with other IEC 60603-7 series connectors.
NOTE Tr.nmision performance cal.gonei: in this PEC stan4ard, ttie term category. e*en uaed in rif.renc. to tranmlse4on performance, refers to those categories de1ried by ISO/IEC 11801

6.5 Transmission characteristics
6.5.1 General
Compliance to this standard, in respect to transmission characteristics, is determined according to specific test methods described in test group EP, see Table 1. The interoperability of connectors compliant to this standard shall be demonstrated by testing the fixed connectors with the full range of free connectors according to EC 60512.27.1002.
All transmission performance requirements apply between the reference planes specified in
IEC 60512-27-100.
