It carries 4 contacts rated 1 A each — enough for the USB power and data pair, with headroom for a bus-powered device. Gold and GXT plating on the contacts, combined with a 1500-cycle mating life, puts this above the typical consumer USB connector. That cycle count matters when the port sees daily plug-unplug in a lab bench or a field-service tool — the contact finish resists fretting corrosion longer than a plain gold-flash part would. That temperature envelope covers unheated industrial cabinets and outdoor telecom shelters where the connector lives through freeze-thaw cycles unpowered. ## Board Lock and Right-Angle Mounting That keeps common-mode noise from coupling into the USB differential pair — a practical concern when the cable runs past a switching power supply inside the enclosure. ## Packaging Choice: Tape & Reel vs Tube The 61729-0010RLF ships in Tape & Reel or Cut Tape, while the 61729-0010BLF, 61729-0011BLF, and 61729-0021BLF are Tube-only. The electricals, footprint, and plating are identical across all four — the only difference is the carrier format. If your pick-and-place line feeds from reels, the RLF suffix is the one to order; if you hand-load or use a tube feeder, the BLF variants save the reel-upcharge.","metaTitle":"Amphenol 61729-0010RLF USB-B Receptacle, 4 Pos, Right Angle","metaDescription":"Amphenol 61729-0010RLF USB 2.0 Type-B receptacle, 4 contacts, right-angle through-hole, Gold/GXT plating, 1500 mating cycles, UL94 V-0, RoHS.
