USB Mini B Receptacle with Through-Hole Anchors
The Hirose UX60SC-MB-5S8(85) is a shielded USB - mini B receptacle from the UX series, carrying 5 contacts and rated for USB 2.0 signal speeds. It mounts right-angle to the board using surface-mount signal tails plus through-hole solder retention posts — the through-hole anchors take the mechanical strain from cable insertion and removal, keeping the SMT joints from fatiguing over the 5000 mating cycle life. Rated 1A at 30VAC, with gold-plated contacts and a shielded copper alloy shell that bleeds EMI to the board ground plane.
Board Layout and Solder Anchoring
The through-hole retention posts are the key layout detail — they require drilled holes in the PCB footprint, not just SMT pads, so the connector resists the lever force of a cable plugged and unplugged repeatedly. Without those anchors, the SMT pads alone would lift after a few hundred cycles.
Mating Cycle Life and Contact Durability
Rated for 5000 mating cycles — well above the 1500-cycle typical for standard mini USB connectors. For a portable device or test fixture that sees daily cable connects, this connector holds its contact resistance without degrading.
