USB cable EFB Elektronik K5250SW.3V2 30 m USB 2.0 A Mini-B Black

The EFB Elektronik K5250SW.3V2 is a 30 m USB 2.0 cable with a standard USB A plug on one end and a Mini-USB B plug on the other. Designed for point-to-point data and power connections, this black cable supports USB 2.0 signaling with a maximum theoretical transfer rate of 0.48 Gbit/s. Its extended length makes it suitable for setups where devices need to be connected over longer distances than typical short consumer cables allow.

Advantages

This cable provides a reliable USB 2.0 connection over a 30 m distance while maintaining the standard USB A and Mini-USB B interfaces for compatibility with legacy devices. The plain black sheath offers a neutral appearance and simple integration into industrial or office environments. The product focuses on functional continuity of data and power delivery where a longer-than-usual cable run is required.

Suitable for

• Connecting legacy devices with Mini-USB B ports to host computers or hubs
• Extended workstation layouts where device and PC are separated by several meters
• Industrial or lab environments that require a standard USB connection over longer distances

Key specifications

• Connector 1: USB A (male)
• Connector 2: Mini-USB B (male)
• USB version: USB 2.0, up to 0.48 Gbit/s
• Cable length: 30 m
• Colour: Black

How to use

Connect the USB A end to the host device such as a computer, hub or power source, and insert the Mini-USB B end into the peripheral device. Ensure both connectors are fully seated to establish a stable data and power link. When deploying over long distances, route the cable to avoid sharp bends, pinch points and sources of electromagnetic interference to maintain signal integrity.

Recommendations

For best results, avoid running the cable in parallel with high-voltage power lines and secure it along trays or cable ties to reduce strain. If you require higher data rates or active signal boosting for very long runs, consider using USB extenders, active repeaters or switching to cables and interfaces that support USB 3.x or network-based solutions.
