IEC 61076-2-111 Ed. 2.0 b:2025

Full Description

IEC 61076-2-111:2025 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 Ø1,0 mm and Ø1,5 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 × 1
screw-locking, see Bibliography.
