USB Extension Cables

USB Extension cables, also known as USB extension leads, provide connection from computers to peripherals, and are similar to standard USB cables. However the primary functionality for USB extension cables is to extend the functionality of a USB port which cannot be easily reached. The majority of USB extension cables go from a male USB connector to a female USB connector. RS have a varied range of USB extension cables that can support either male or female USB A, USB B, Micro USB B and Mini USB B connectors, and features products from trusted brands such as Harting, Startech, and our own RS PRO, among others.

Where are USB extension cables used?

They can prevent needing to access the back of a desktop computer, which may be difficult to do due to the surrounding environment or position of the computer, and instead allow for the utilisation of the USB ports at the front of the unit, which may be arguably easier to access.

Alternatively if you have a peripheral such as a printer, of which the cable is too short to reach the USB port, the extension cable can be used to breach the distance between them. With the extension cable, you do not have to rely on a wireless network to locate the printer, which also requires the printer (or other peripheral) to be within close proximity to the computer and this may not be possible.

How long are USB extension leads?

USB extension leads are available in various lengths to suit a range of applications and can vary from around 0.5m to 35m.

Types of USB connectors:

• USB A
• USB B
• Mini USB B
• Micro USB B

Note: Some USB connectors are available in both male and female (plug or socket) versions.

IP Ratings for USB Extension Cables

IP ratings describe how waterproof the cable is. If you are looking for a cable which is water resistant, around IP40 is suitable. If you require something which is waterproof, you should look at a higher number such as IP67 or IP68.
