This standard covers a group of related two-part connectors for printed boards and cable connectors associated with printed backpanels. The group covers high-density connectors having up to 96 miniature contacts for low-voltage applications, hereinafter called "signal contacts", connectors having up to 6 high current contacts, hereinafter called "power contacts", combined with up to 42 signal contacts and a range of 4, 10, 20 and 64 way female cable connectors and associated male parts for making connection to the backpanel or to the printed board (see Figures 1 and 2, pages 9 and 11). The board-mounted connectors with female contacts are provided with terminations suitable for printed boards in accordance with IEC Publication 326 and using a grid of 2,54 mm (0,100 in) as laid down in IEC Publication 97. A first range of fixed connectors with male signal contacts is assembled on the backpanel by signal contacts and moulded housings. These male signal contacts have compliant press-in sections (optional additional soldering) suitable for use in backpanels with a grid of 2,54 mm (0,100 in) according to IEC Publication 97. (The press-in technique is under consideration.) The individual male contacts are suitable for additional wrapping (see Figure 1). A second range of independent male connectors with solder terminals for printed backpanel mounting is included (see Figure 2). First-to-make contact facilities can be provided on the connection between the printed board and the backpanel. The two-row cable connectors are intended to connect round cables having up to 64 cores of 0,25 mm (0,010 in) or 0,5 mm (0,020 in) diameter conductors. Connections are made with the insulation displacement technique (under consideration for specification). Furthermore, male connectors for printed board mounting to mate with these cable connectors are included (see Figure 2). This standard shall be used in conjunction with IEC Publications 50(581), 97, 194, 326, 352-1, 512, 603-1 and 603-2.
