IEC 63171:2021 pdf download – Connectors for electrical and electronic equipment – Shielded or unshielded free and fixed connectors for balanced single-pair data transmission with current-carrying capacity – General requirements and tests

IEC 63171:2021 covers both shielded and unshielded connectors, available in free and fixed configurations, and can be either circular or rectangular. These connectors are specifically designed for balanced single-pair data transmission and include current-carrying capabilities.

IEC 63171:2021 details the IEC 63171 series, specifying the common mechanical, electrical, and transmission characteristics, along with the environmental requirements and necessary testing procedures.

IEC 63171:2021 does not specify a particular mating interface; instead, comprehensive specifications for mating interfaces compliant with this standard are available in the series of detailed specification standards known as IEC 63171-X (where X denotes a specific type).

Both shielded and unshielded connectors within their respective categories are interoperable regarding their transmission performance and can be exchanged. However, the shielded version offers superior performance in terms of alien crosstalk and coupling attenuation.
