The Schneider Electric HMIYDUSBCA111 is a USB Clamp Type B (1 port) connection accessory for the Harmony iDisplay range. It's the part that secures the USB cable at the display end — a small mechanical clamp, not a data converter or hub. If you're maintaining a line with iDisplay panels and the USB retention clip is missing or broken, this is the factory part for that job.
This USB clamp is specific to the Harmony iDisplay family. It's a Type B port clamp, single-port. If you're swapping a panel or retrofitting a USB connection on an existing iDisplay install, this is the mechanical retention piece that keeps the cable from vibrating loose in an industrial enclosure. No electronics inside — just the clamp body.
