This part of IEC 61076 covers 10-way, shielded, free and fixed rectangular connectors for data
transmission with frequencies up to 500 MHz and specifies the common dimensions,
mechanical, electrical and transmission characteristics and environmental requirements as well
as test specifications respectively.
Connectors covered in this document are provided in three codings that differ only for the
position of the polarization key and keyway, in view of their differently intended use:
• Connectors Type A and C are intended for 10/100 Mbit/s as well as for 1/ 2,5 / 5 /10 Gbit/s
Ethernet communication.
• Connectors Type B are intended for all other non-Ethernet applications such as signalling,
serial or other industrial bus communication systems.
