4.5 SATA Device Connector Definition
Please note that all pins are in a single row, with a 1.27 mm (50 mil) pitch diameter. There are three power
pins for each voltage source. One pin from each voltage is utilized for pre-charge when installed in a blind-
mate backplane configuration.
The notes on the mating sequence apply to the case of backplane blind mate connector.
When the drive is inserted, the ground pins and the pre-charge pins are in contact first followed by the remaining pins.
Table 4-1 lists the signals connection on the SATA interface and power connector. It is based on SATA 1.0a
Specifications. Note that pin numbers is designated from the pin farthest from power segment.
