UNITEK Y-279 USB 2.0 Active Extension Cable 20M 480Mbps for Webcam Printer Microphone
The UNITEK Y-279 is an active USB 2.0 extension cable. It measures 20 meters in length. The cable features a built‑in USB 2.0 extension chipset. This ensures stable signal transmission over the full 20 meters without needing additional cables. It supports data transfer speeds of up to 480Mbps (USB 2.0 Hi‑Speed). It is also backward compatible with USB 1.1. The cable is perfect for extending webcams, printers, microphones, and external drives over very long distances.
The cable is built with high‑quality materials. It has gold‑plated connectors that resist corrosion. The conductors are made of copper wire for enhanced signal stability. The power and ground wires are 26AWG thick. The cable includes aluminum foil and braid shielding. This protects against electromagnetic interference. The result is stable, reliable data transmission over 20 meters.
This active extension cable includes an extra USB‑A power port. You can connect an external USB power supply (5V, not included) to this port. This provides additional power for high‑consumption devices. Webcams, printers, and USB microphones often need this extra power. Without external power, the cable still works for low‑power devices. The cable is plug and play and hot‑swappable. No drivers are required for Windows, macOS, or Linux.
Use this cable to position your USB devices exactly where you need them. Extend a webcam across a large conference room. Place a printer far from your computer. Run a microphone to a stage or sound booth. The UNITEK Y-279 delivers reliable, long‑distance USB 2.0 connectivity.
