The European Committee for Electrotechnical Standardization (CENELEC) has announced EN 60603-7-81:2016. This standard is titled, “Connectors for electronic equipment – Part 7-81: Detail specification for 8-way, shielded, free and fixed connectors, for data transmissions with frequencies up to 2 000 MHz.”
IEC 60603-7-81:2015 Covers 8-way, shielded, free and fixed connectors, references dimensional, mechanical, electrical and environmental characteristics and tests in IEC 60603-7, and specifies electrical transmission requirements, including power sum alien (exogenous) crosstalk, for frequencies up to 2 000 MHz. These connectors are typically used as “category 8.1” connectors in “class I” cabling systems specified in ISO/IEC 11801. These connectors are intermateable and interoperable with other IEC 60603-7 series connectors as defined in Clause 2 of IEC 60603-7. These connectors are backward compatible with other IEC 60603-7 series connectors, except IEC 60603-7-7 and IEC 60603-7-71 connectors. Key words: Connectors, Shielded, Free and Fixed Connectors
