USB-A Plus Power in One Shell — 8-Contact Combo Plug
The FCI 74233-202LF is a USB-A (USB TYPE-A) and Power combo plug, meaning it packs four standard USB 2.0 signal/power contacts plus four additional power contacts into a single shielded shell. That 8-contact layout lets a single cable handle both data and higher-current charging — the signal contacts are rated 1.5A per circuit, while the power contacts carry 3A per circuit at 24V. The red insulation color visually flags this as the power-combo variant, not a standard USB plug. The gold, GXT™ contact finish keeps contact resistance stable across those cycles, and the shielded steel/stainless shell contains EMI from the USB 2.0 data lines — no additional ferrite needed for typical cable runs.
Dual Current Paths — Signal vs Power Contacts
The four USB 2.0 signal contacts are rated 1.5A each; the four power contacts are rated 3A each at 24V. This 8-contact combo part adds a dedicated power pair without needing a separate DC jack.
