39、 connectors M8 screw-locking or with nominal diameter 8 mm snap-locking, typically used for industrial process measurement and control. These connectors consist of fixed and free connectors either rewireable or non-rewireable. Male connectors have round contacts of diameter 0,6 mm, diameter 0,7 mm a

40、nd diameter 1,0 mm. Throughout this detail specification, dimensions are in mm. NOTE M8 is the dimension of the thread of the screw-locking mechanism of these circular connectors. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are
