USB micro B Plug — Hirose ZX360 Series
The Hirose ZX360-B-10S-UNIT is a USB micro B plug from the ZX360 series, carrying 10 contacts and supporting USB 3.2 Gen 1 (Superspeed) data rates. This is the plug (male) half of the micro USB interconnect — mates with the ZX360-B-10P-UNIT receptacle. Rated for 1.8A per contact at 30VAC, with gold-plated contacts that handle the 10000 mating cycle rating without significant wear.
Lifecycle and Sourcing — Obsolete Status
The ZX360-B-10S-UNIT is officially listed as Obsolete by Hirose. No direct replacement or successor part number is provided in the available documentation.
What the 10000 Mating Cycles Means
The 10000 mating cycle rating is well above the typical 1500-5000 cycles for standard micro USB connectors. This makes the ZX360-B-10S-UNIT suited for applications requiring frequent connect/disconnect — test equipment, handheld devices, or docking stations. The gold contact finish supports this cycle life without the fretting corrosion that would appear on tin-plated contacts after repeated matings.
The steel, stainless shell provides basic EMI shielding in the unshielded configuration — adequate for USB 3.2 Gen 1 signal integrity in typical cable assemblies.
