The 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 (9.1 meters) 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' 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.
