IEC 61076-4-105:1995 is a detail specification. A complete connector consists of a fixed connector and a free connector. The fixed connector is mounted vertically or at a right angle to the printed circuit board. The free connector is terminated to a cable consisting of three to eight conductors (shielded or unshielded). The fixed and the free connector have a range of three to eight contacts. Each connector is keyed to prevent mismating. Examples of contact arrangements are shown in figure 2.Rating and characteristics:Wording voltage: 30 V a.c. r.m.s. or d.c.Current rating: 1 A max.Insulation resistance: 1 000 M ohms min.Climatic category: PL1: 55/100/56, PL2: 55/100/21, PL3: Not applicablePrinted board thickness: 1,58 mm (0,062 in)Contact spacing: varies with number of contacts.
