The Siemens 6AV7674-1MF00-0AA0 is a USB interface for front mounting in a SIMATIC HMI Extension Unit, terminating in a USB 2.0 Type A socket on a 0.7 m cable. It mounts through a threaded ring and carries IP65 protection with the cap closed, dropping to IP20 at the front when the cap is open for connector access. The assembly ships with the socket, cable, connector and one protective cap.
The IP65 rating only applies with the protective cap closed; the front drops to IP20 once the cap is open and the USB connector is in use, so the enclosure choice around the Extension Unit should account for exposure during the time the port is actively connected. The 0.7 m cable length sets how far the connected USB device can sit from the panel face, which matters when routing a memory stick or reader outside the cabinet.
