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

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 (V
x
) must be terminated.
