It carries 4 contacts in a single port, configured for USB 2.0 signaling at 1A per contact. Gold, GXT™ plating on the contacts ensures corrosion resistance over the rated 1500 mating cycles — a figure that signals this connector is specified for equipment that sees repeated plug-unplug duty, not a single-mate cable harness. The 4-contact layout follows the standard USB Type-B pinout — VBUS, D-, D+, and GND — so no pinout confusion when mating with a standard USB-B cable plug. ## 1500 Mating Cycles and the Gold GXT Finish The 1500-cycle rating is well above the 500-cycle baseline of a basic USB connector. The GXT™ gold plating (a proprietary hard-gold alloy from FCI) reduces contact wear and maintains stable contact resistance across those cycles. For a procurement decision, this means the 61729-1010BLF is suited to test equipment, kiosk ports, or industrial HMI panels where the USB port is accessed daily — not a consumer peripheral where 500 cycles is the norm.","metaTitle":"Amphenol FCI 61729-1010BLF USB-B Receptacle, 4 Pos, R/A","metaDescription":"61729-1010BLF USB 2.0 Type-B receptacle, 4 contacts, right-angle through-hole, shielded, gold GXT plating, board lock, 1A, 1500 cycles, UL94 V-0.
