This International Standard describes circular connectors M12 typically used for industrial
process measurement and control. These connectors consist of fixed and free connectors
either rewireable or non-rewireable, with screw-locking. Male connectors have round contacts
Φ 0,6 mm, Φ 0,76 mm, Φ 0,8 mm and Φ1,0 mm.
The different codings prevent the mating of these coded male or female connectors to any
other interfaces and cross mating between the different codings.
NOTE M12 is the dimension of the thread of the screw locking mechanism of these circular connectors.
