Annotation of standard text ČSN EN IEC 61076-2-111-ed.2 (354621):

This part of IEC 61076 2 describes 4- to 6-way circular connectors with M12 screw-locking with current ratings 8, 12 or 16 A per contact and voltage ratings of 50 V AC / 60 V DC or 630 V according to their coding, that are typically used for power supply and power applications in industrial premises.
These connectors consist of both fixed and free connectors, either rewirable or non-rewirable. Male connectors have round contacts 1,0 mm and 1,5 mm.
The different codings provided by this document prevent the mating of differently coded male or female connectors to any other similarly sized interfaces, covered by other standards and the cross-mating between the different codings provided by this document.
NOTE 1 - M12 is the dimension of the thread of the screw locking mechanism of these circular connectors.
NOTE 2 - Several other IEC standards are available covering additional styles of circular connectors with M12 x 1 screw-locking, see Bibliography
