Amphenol Pcd also offers harsh environment USB Memory Keys with capacities ranging from 1-256GB. Threaded and bayonet coupling versions are available.
Another option is the USBFTV SC which offers a new spring loaded coupling solution, particularly for applications requiring quick disconnect. The system consists of a circular spring within the receptacle keeping the plug mated and creating an internal coupling mechanism. Amphenol has also developed memory keys around this connector series.
