Hirose ZX360D-B-10P(30) — USB 3.2 Micro-B Receptacle with 10000-Cycle Life
The Hirose ZX360D-B-10P(30) is a 10-contact USB micro-B receptacle from the ZX360 series, rated for USB 3.2 Gen 1 (SuperSpeed) data rates.
What the 10000 Mating Cycles Mean for Field Service
The 10000-cycle rating is the defining spec on this part. A standard USB micro-B connector is typically good for 5000 cycles; the ZX360D-B-10P(30) doubles that. The palladium-nickel plating on the contacts resists fretting corrosion and maintains contact resistance over repeated insertions — relevant for test equipment, point-of-sale terminals, or any device where the cable is plugged and unplugged daily. The steel and stainless shell/shielding material adds mechanical robustness against the wear of frequent mating.
USB 3.2 Gen 1 Backward Compatibility
Rated to USB 3.2 Gen 1 (5 Gbps SuperSpeed), the ZX360D-B-10P(30) is backward compatible with USB 2.0 and USB 1.1 devices. The 10-contact micro-B layout carries the differential pairs for SuperSpeed data lanes in addition to the standard USB 2.0 D+/D- lines, VBUS, and ground. A USB 2.0 plug will mate mechanically and function at reduced speed — the extra contacts simply go unused.
The ZX360-B-10S-UNIT(30) is the mating plug for this receptacle, also from the ZX360 series. Both carry 10 contacts and the same USB 3.2 Gen 1 rating. The plug is rated 1.8 A per contact versus the receptacle's 1 A per contact — the receptacle is the current-limiting half in the mated pair. The plug uses gold contact finish and ships in tray packaging rather than tape and reel. For a BOM that needs both halves, order the receptacle and plug separately.
Mounting and Footprint Notes
The ZX360D-B-10P(30) is a surface-mount, right-angle receptacle with a horizontal mounting feature. The steel and stainless shell provides EMI shielding and mechanical strength for the USB interface.
