This specification covers the requirements for application of CHAMP .050 Series I Blindmate plug and receptacle SCA--2 for printed circuit (pc) board application. These plug and receptacles are available in 20, 40, and 80 positions and contain through--hole contacts or compliant pin contacts on 1.27 centerline spacing. The plugs are available in vertical and straddle mount; and the receptacles are available in right--angle, vertical, press--fit vertical, extended height press--fit vertical, and extended height vertical. These connectors are fully compatible with CHAMP .050 Series I SCA--1 board--to--board connectors. The plugs and receptacles contain boardlocks to provide additional stability when placed on the pc board. End cavities are marked with a number to provide circuit identification. The plug and receptacles may be placed on the pc board by hand or automatic application tooling.
