Detail Specification for Trapezoidal Connectors with Nonremovable Ribbon Cable Contacts on 1.27 mm Pitch Double Row Used with Single Connector Attachments (SCA2)
"This Standard applies to a family of connectors having the following characteristics: ? unshielded@ ? trapezoidal-shaped mating interface@ ? 1.27 mm pitch spacing of contacts on a double row@ ? 40 and 80 positions@ ?for board-to-board and a wire-to-board applications. All dimensions in this document apply to the unmated finished product (after assembly to printed circuit boards / backplanes). While the SCA-2 connectors in this specification should intermate with those termed ""SCA- 1"" there is no specification to control the SCA-1 dimensions and the lead-in features and the different contact position lengths are not present on the SCA-1 connectors. It is therefore not recommended that SCA-2 connectors be used with SCA-1 connectors in a blind mating application. This Standard establishes uniform specifications@ testing requirements and quality assessment procedures. It is intended to be used in conjunction with sectional specification EIA 700A000. Recommended method of mounting Fixed board (receptacle) connector is mounted on the backplane and has female contacts with straight solder terminations. Information on the availability of components qualified to this standard is given in the qualified product list. Number of contacts or contact cavities are 40 and 80 positions.
