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