The TE Connectivity 2023246-2 is a 22-position SATA receptacle in a right-angle surface-mount package. The 30.0µin gold contact finish handles the mating cycles a drive bay sees — repeated insertions without the contact fretting you get from a tin-plated part.
Mating and termination — what bolts in
The 22 positions match the standard SATA signal-and-power interface. Gold-on-gold contact interface with the mating plug — no galvanic mismatch. The board guide takes the shear load during insertion so the solder joints don't take the hit.
