G14A42111C12HR OCuLink 4X Right-Angle Receptacle (Amphenol)

Amphenol G14A42111C12HR is a 42-position OCuLink 4X board receptacle (SFF-8611 cable, SFF-8621 fixed side) for a PCIe x4 link: four transmit and four receive pairs, a 100 MHz reference clock pair and the PERST# / cable-present sideband, with a ground contact between every pair. Right angle, surface-mount contacts at 0.5 mm pitch in two staggered rows, a stainless shell with four 2.90 mm through-hole legs (shell option C), 15 u" gold contacts, LCP housing, tape and reel.

Pinout (SFF-9402 Table 6-1, root/controller side)

Row A carries the host-receive pairs (PER) and the reference clock, row B the host-transmit pairs (PET) and PERST# / CPRSNT#. On an endpoint the PET/PER names swap; the cable is straight through.

  • The manufacturer STEP is behind an Amphenol account login; this page's model is not Amphenol's. It was written by stepbox.py (plain AP214 boxes) and checked with step2glb (bbox -6.83..6.83 x -7.72..1.98 x -2.65..3.90 mm). Full record: provenance.json.
