PCB edge connectors are expensive when found, and can be hard to source.  Thus, we've purchased 1000 to bring the costs down and ensure adequate supplies.  These are brand new, double-sides card edge connectors with PCB-installable leads (.6mm lead width for .100" connectors, 1mm lead width for .156" connectors).  Use them as a through-hole component or solder to the edge of the PCB for a parallel connection.  Datasheets are available by request.
