The Amphenol PSAS5F3130031TR is a 68-position SAS/PCIe receptacle from the PSAS series, designed for high-speed internal storage and server backplane interconnects. It uses a surface-mount termination with features that support automated assembly: board guide, mating guide, pick-and-place pad, and solder retention.
The 68 positions match the full-width SAS connector footprint common on enterprise backplanes.
This is a surface-mount receptacle — the solder tails reflow onto the PCB pads. The pick-and-place pad and solder retention features keep it aligned during reflow without secondary hand-soldering. It mates with the corresponding SAS/PCIe plug header (Amphenol PSAS series), which carries the cable-side or drive-side interface. The mating guide ensures the plug aligns before the contacts engage, reducing stubbing damage on the fine-pitch terminals.
