IEC 61076-3-122:2021 covers 8-way, shielded, free and fixed rectangular connectors for I\/O and data transmission with frequencies up to 500 MHz. It is intended to specify the common dimensions, mechanical, electrical and environmental characteristics and tests for this family of connectors. Connectors complying with this document provide an ingress protection level of IP20; however, they are particularly suited for industrial environments with a high level of vibration. There are two classes of connectors defined in this document, indicated by “class A” and “class B” which are distinguished by some electrical and mechanical characteristics to meet the particular sets of requirements of some industrial applications. Class A meets the requirements defined in Ed.1 of this document. With the two classes A and B, the two codings Type I and II, and the two sets of transmission requirements according to the component categories Cat 5 and Cat 6A as defined in ISO\/IEC 11801-1, this document specifies 2 \u00d7 2 \u00d7 2 = 8 variants. All connectors covered by this document feature a current-carrying capacity beyond the minimum requirement of 0,75 A per pin for an ambient temperature of 60\u00b0 C as defined in ISO\/IEC 11801 1. This second edition cancels and replaces the first edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Title modified. b) Introduction of two sets of requirements for connectors of “class A” and “class B” where class A matches the requirements defined in the previous edition. c) Definition of new performance requirements for frequencies up to 500 MHz in addition to the performance requirements up to 100 MHz provided with the previous edition. d) Re-structuring to reflect the commonalities of and differences between connector Type I and Type II. e) Revision of drawings to clarify some dimensions. e) The derating diagram has been corrected to align it with the upper limiting temperature in the climatic category, with no reduction of performance for the target applications.<\/p>\n
