1. INTRODUCTION
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.
When corresponding with personnel, use the terminology provided in this specification to facilitate your
inquiries for information. Basic terms and features of this product are provided in Figure 1.

C. Recommended Layout
The boardlock holes and contact holes in the pc board must be precisely located to ensure proper
placement and optimum performance of the plug or receptacle. The pc board must be designed using the
dimensions provided in Figure 4.
NOTE
