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 pins and the other ground pins.

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

3.There are three power pins for each voltage. One pin from each voltage is used for pre-charge when installed in a blind-mate backplane configuration.

4.All used voltage pins (Vx) must be terminated.
