The International Electrotechnical Commission (IEC) has released IEC 61076-2-111:2017 PRV and is now available on the IEC webstore. This pre-release version of the standard applies to circular connectors for electrical and electronic equipment and details specifications for power connectors with M12 screw-locking.
Description: “IEC 61076-2-111:2017 specifies 4 to 6-way circular connectors with M12 screw-locking with current ratings up to 16 A and voltage ratings of 63 V or 630 V, that are typically used for power supply and power applications in industrial premises. These connectors consist of both, fixed and free connectors either rewireable or non-rewireable, with M12 screw-locking. Male connectors have round contacts Ø1,0 mm and Ø1,5 mm. The different codings provided by this document prevent the mating of accordingly 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. M12 is the dimension of the thread of the screw locking mechanism of these circular connectors.”
