IEC 61076 describes circular connectors with M5 screw-locking

This part of IEC 61076 describes circular connectors with M5 screw-locking, 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 non-rewirable or rewirable and free connectors non-rewireable.

Male connectors have round contacts ^∅ 0,48 mm.

1.2      Recommended method of termination

The contact terminations shall be of the following types: screw, crimp, insulation piercing, insulation displacement, press-in or solder.

1. 2.1    Number of contacts or contact cavities

3  and 4 contacts.

1.3      Ratings and characteristics

Rated voltage         3 contacts  60 V d.c. or a.c.

4 contacts  60 V d.c. or a.c.

Current rating	3 contacts  1A
	4 contacts  1A
Insulation resistance	: 108 Ω min.
Climatic category	: see 4.1 Table 4
Contact spacing	: see Clause 3
