Panel-mount USB feedthrough connectors from Seetronic in the standard D-type chassis footprint, covering USB 2.0 Type-A (SAUSB-W-B and MAUSB-W-B) and USB 3.0 Type-C (SCCMCDF-01), all sealed to IP65 with rubber covers over the port.

The D-type format means these drop into the same panel cut-out as XLR chassis connectors, so a USB point can sit alongside audio and data connections on a rack panel, lectern, stagebox or wall plate, and a damaged front port becomes a quick swap rather than a rewire. The covers maintain the IP65 rating against dust and water whenever the port is not in use, which is what you want on exposed or outdoor panels. The Type-C version is a straight female-to-female pass-through rated for over 10,000 mating cycles, the sensible pick where modern interfaces need USB 3.0 bandwidth, while the Type-A models cover the huge base of existing peripherals and control surfaces.
