This drawing outlines the requirements for a specific member of a family of compact high contact density (.050 inch (1.27 mm)), high performance two piece electrical connectors. These connectors are intended for printed circuit board (plug in dual heat sinked daughter board modules, and fixed backplanes) applications utilizing surface mount daughter board and compliant pin backpanel termination techniques. The connector family includes members,which provide combinations of low power signal contacts, power contacts, shielded contacts and optical termini. The connector family offers severe operating environment performance capability, such as protective hoods, contact sealing, interfacial seals, electrostatic shielding and other advanced capabilities.
