Scope This part of IEC 61076 describes circular connectors with M5 screwlocking, typically used for industrial process measurement and control. NOTE M5 is the dimension of the thread of the screw locking mechanism of these circular connectors. These connectors consist of fixed nonrewirable or rewirable and free connectors non rewireable. Male connectors have round contacts ? 0,48 mm. Remended method of termination The contact terminations shall be of the following types: screw, crimp, insulation piercing, insulation displacement, pressin or solder. Number of contacts or contact cavities 3 and 4 contacts. Ratings and characteristics Rated voltage 3 contacts 60 V . or . Current rating 4 contacts 3 contacts 60 V . or . 1 A 4 contacts 1 A Insulation resistance : 108 Ω min.
