KanexPro EXT-USB250M extends USB 2.0 at 480Mbps up to 50m/164ft over Cat5e/6 with dual USB-A ports — TX bus-powered, no drivers, ideal for webcams, touch…
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.

Questions
- What is the maximum transmission distance?
- 50m/164ft for most USB 2.0 devices. Note: some USB 2.0 hubs are limited to 40m/131ft due to timing requirements.
- Does it work over existing Cat5e infrastructure?
- Yes — supports Cat5e, Cat6, and Cat6a up to 50m/164ft.
- Does the Transmitter need its own power adapter?
