USB extension cables are used to extend the connection to a large number of devices, such as computer keyboards, printers, mice, and SD card readers. Our USB cables can work with both USB 1.1 and USB 2.0 devices. Extension cables for USB typically come with A connectors on both sides, one male and one female. This allows standard USB devices to attach on the female end. A USB type A cable used by most devices will plug into the female end of the extension cable; the cable will then plug into the computer. USB can be extended up to 9.5 to 16 feet passively; for longer reach you can add an USB active extender for up to 80 feet on most devices.
