What It Is — A Shield, Not a Connector
The Hirose ZX20-B-SLDC is a shield for a USB microUSB B plug — it's the metal shell that wraps the plug body, not the plug itself. Listed under the ZX20 series, this part is specified for use with USB microUSB B plugs, meaning it fits the standard micro-B form factor found on countless mobile and embedded devices. The shield provides the EMI containment and mechanical retention that the plastic housing alone can't deliver.
This shield mates over a microUSB B plug assembly to complete the connector's outer envelope. In a typical harness build, the shield is soldered or crimped to the cable braid and then overmoulded — it's the part that gives the plug its distinctive metal-can feel and handles the ground return path. The ZX20-B-SLDC is a bottom-positioned shield variant; the plug sits above it in the assembly stack.
Packaging for the Build Line
Available in both Tape & Reel (TR) for automated pick-and-place assembly and Cut Tape (CT) for prototype or low-volume work. The reel option keeps the shield oriented consistently for the nozzle, while the cut tape lets a bench assembler grab one at a time without opening a full reel.
