IEC 63171-6 published: Standard industrial interface for SPE set

IEC 63171-6 specifies the Single Pair Ethernet (SPE) interface “Industrial Style” as proposed by the HARTING Technology Group and is the future standard interface for industrial SPE applications.

On January 23rd the international standard for Single Pair Ethernet interfaces in industrial applications was published with IEC 63171-6. The editor is the IEC committee SC 48B copper connectors. The mating face standard IEC 63171-6 T1 Industrial Style was the first standard submitted by HARTING to SC 48B for a Single Pair Ethernet mating face as early as 2016. “This early initiative is now paying off and 2020 users finally have a reliable investment basis for future-proof IIoT networks based on Single Pair Ethernet,” explains Ralf Klein, Managing Director of HARTING Electronics.

IEC 63171-6 (Industrial Style) is a complete standard document with all necessary specifications and test sequences, which is incorporated into current SPE cabling standards of the ISO/IEC 11801-x series of standards for structured cabling. The implementation of SPE in the ISO/IEC 11801 documents is very important because only in this standard, the cabling channels are described with all necessary parameters (length, number of connections, bandwidth and the complete set of transmission parameters including NEXT, FEXT, shielding properties etc.) with relation to the environment – MICE and can therefore be metrologically verified after installation. This connection of component standards to connectors and cables provides all users of SPE with clear guidelines for the construction and testing of appropriate transmission links.
