USB 3.0 B to A multimedia tray. Equipped with an approximately 20 cm long breakout cable, i.e. a USB-B socket is located on the front of the tray and a USB-A socket is located on the rear of the tray at the end of the breakout cable. This design helps reduce the time required for installation at site due to the fact that only the preassembled USB-A cable needs to be plugged in on the back. All plug contacts are plated with 24 carat gold. In combination with the mounting frame, any two multimedia trays (alternatively one tray combined with a blind cover) may be used for each frame with the internal dimensions of 50x50 mm.
