USB kabel EFB Elektronik USB 2.0 A / Mini B 3 m K5251SW.3

The EFB Elektronik USB 2.0 A / Mini B 3m K5251SW.3 is a 3‑metre data cable designed for connecting devices with a Mini‑USB B port to computers or chargers with a standard USB A port. The cable supports USB 2.0 data transmission rates up to 480 Mbit/s and is supplied in a black, moulded‑plug design with a combination of foil and 80% braided shielding for reliable signal integrity. Wire gauges are AWG28 for data and AWG20 for power, making the cable suitable for both data transfer and device charging within USB 2.0 specifications.

Advantages

This cable provides a long 3 m reach that facilitates connection between devices that are not close to each other while maintaining USB 2.0 transfer speeds up to 480 Mbit/s. The foil plus 80% braid shielding reduces electromagnetic interference and improves signal stability. Molded plugs increase mechanical durability at connector joints and the black outer jacket offers a neutral, professional appearance that resists visible wear.

Suitable for

• Connecting digital cameras and camcorders with Mini‑USB B ports to PCs for file transfer
• Linking portable external hard drives and media players that use a Mini‑USB B connector
• Charging and syncing older smartphones, GPS units, and other portable devices with Mini‑USB B
• Workstations or home setups that require a longer cable run without active extenders

How to use

Connect the USB A male end to an available USB port on your computer, laptop, or USB charger, and insert the Mini‑USB B male end into the device's Mini‑USB socket. Ensure both connectors are oriented correctly and seat fully to establish a secure connection. For data transfer, allow the host device to recognise the connected peripheral and follow on‑screen prompts for file operations. When charging, verify that the host port can supply the required current for the target device.

Recommendations

To maintain optimal performance, avoid sharp bends near the connector ends and keep the cable away from strong electromagnetic sources. For long‑term reliability, unplug by gripping the moulded plug rather than pulling on the cable and store the cable without tight knots.
