Prolunga USB 3.0 helos 288349 — 0,5 m, nero, maschio-femmina

Helos USB 3.0 extension cable, 50 cm long, male-to-female USB A connectors in black. The cable extends an existing USB 3.0 connection while supporting the USB 3.0 specification to maintain high-speed data transfer between host and peripheral devices. It features shielded construction and gold-plated connectors for reliable signal transmission and reduced interference.

Advantages

The shielded design with foil and braid and gold-plated USB A contacts improves signal integrity and reduces electromagnetic interference. At 50 cm length the cable provides added reach without excess slack and is flexible enough for desktop or portable setups. It is compatible with USB 3.0 devices and carries standard markings such as USB 3.0, REACH and RoHS2.

Suitable for

• Extending USB 3.0 connections to external hard drives and SSDs
• Connecting USB peripherals (keyboards, mice, hubs) when the port is hard to reach
• Extending connections for mobile devices and chargers that use USB A
• Temporary or permanent desktop cable routing where a short extension is needed

How to use

Plug the USB Type A male connector into the host USB port (computer, hub or charger) and connect the USB Type A female end to the device or cable you want to extend. Ensure both connected devices support USB 3.0 for maximum data rates; the cable is backward compatible with USB 2.0/1.1 but data speed will follow the lowest connected specification. Route the cable to avoid sharp bends and sources of strong electromagnetic interference.

Recommendations

For best performance, use this 50 cm Helos USB 3.0 extension with short, high-quality USB 3.0 cables and avoid daisy-chaining multiple passive extensions. Keep connectors clean and avoid excessive tension on the cable to preserve connector plating and shielding.
