1 Scope
This part of IEC 61076‑2 covers shielded and unshielded, free and fixed circular connectors without breaking capacity (COC) for power, signal and data transmission, and specifies the common dimensions, mechanical, electrical and transmission characteristics and environmental requirements as well as test specifications, respectively.
NOTE 1 As all the connectors described in this document are equipped with shielded data transmission portions, the attribute “shielded” or “unshielded” refers to the additional presence or lack of a shielded connector body.
The connectors described in this document are equipped with an M12, M17, M23 or M40 screw-locking mechanism or a quick-locking mechanism with a size derived from those. Fixed and rewirable connectors with male or female contacts, mateable with Mxx screw- or quick-locking plugs.
This document provides multiple mating interfaces each of which is associated with a coding preventing the mating of incompatible male and female connectors. The individual codings differ by their numbers of ways, pin layouts and thicknesses, and thus by their power and data transmission capabilities. These codings are referred to as “Type x” where ‘x’ represents an Arabic number.
The connectors described in this document are intended to be used in one-cable automation applications which require various combinations and levels of power up to 600 V AC/ DC and up to 70 A, and either signal or data transmission, or both, with frequencies up to 600 MHz.
NOTE 2 The requirements (or information) described in this document facilitate data transmission through the following Ethernet media systems as defined in IEEE 802.3:
single-pair Ethernet (10BASE-T1, 100BASE-T1, 1000BASE-T1);
Fast Ethernet (100BASE-TX);
Gigabit Ethernet (1000BASE-T);
10-gigabit Ethernet (10GBASE-T).
