The Tripp Lite U042-030 USB 2.0 Hi-Speed A/B Active Repeater Cable (M/M) allows you to connect a USB-B device to a computer up to 30 feet away with no danger of signal loss or decrease in performance. Connect the USB-A plug to a USB port on your computer or hub and the USB-B plug to a USB-B peripheral, such as a printer or scanner. A built-in bus-powered repeater ensures peak USB 2.0 signal quality. Backward compatible with previous USB generations, this 30-foot USB cable supports data transfer rates up to 480 Mbps.The U042-030 works with all computers, devices and cables with USB-A or USB-B connectors, and provides up to 150mA of power to the connected USB-B device. An external power supply or powered USB 2.0 hub is required for power applications stronger than 150mA. You can hot-swap connected devices - for instance, unhook your printer and connect a scanner - without having to power down the computer.Premium foil and braid shielding delivers reliable, error-free signal quality and protection from EMI/RFI line noise that can distort or destroy data. Molded connectors with corrosion-resistant gold-plated contacts provide maximum conductivity and minimize data loss. Integral strain relief gives the cable extra flexibility, reduces stress, and helps the cable and connectors move freely without cracking. Features Connects a USB-B Device to a Computer Up to 30 ft.
