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.
•
All used voltage pins (V
x
) must be terminated.
