Notes:

1.All pins are in a single row, with a 1.27 mm (0.050”) pitch.

2.The comments on the mating sequence apply to the case of backplane blindmate connector only. In this case, the mating sequences are:

•the ground pins P4 and P12.

•the pre-charge power pints and the other ground pins.

•the signal pins and the rest of the power pins.
