The KanexPro EXT-USB250M extends USB 2.0 at 480Mbps up to 50 meters (164ft) over a single Cat5e/6 cable — delivering two USB-A ports at the remote end for webcams, touch screens, printers, HID devices, and USB hubs. The Transmitter draws power directly from the host USB-B port, while the Receiver uses a compact 5V/1A adapter. Completely plug-and-play with no driver installation required.
Designed for smaller conference rooms, classrooms, and digital signage environments where 164ft of USB reach is sufficient, the EXT-USB250M is the compact, cost-effective entry point in the KanexPro USB extender range. Backward compatible with USB 1.1 and backed by KanexPro’s 3-year parts and labor warranty.
