USB cables, or Universal Serial Bus cables, are widely used for connecting various electronic devices to each other or to a computer. They provide a standardized interface for data transfer, power supply, and peripheral connectivity. USB cables have different types and connectors, each designed for specific purposes and device compatibility. 

It's important to note that USB cables can have different versions, such as USB 2.0, USB 3.0, USB 3.1, and USB 3.2, which determine their maximum data transfer speeds. The USB cable you need will depend on the specific devices you want to connect or charge.

### USB Cable Types
- [**USB Type-A**](https://uk.rs-online.com/web/c/cables-wires/computer-cables/usb-cables/?applied-dimensions=4290466049,4290466102): This is the most common USB connector and is rectangular in shape. It is used for connecting devices like computers, laptops, power adapters, and USB hubs.
- [**USB Type-B**](https://uk.rs-online.com/web/c/cables-wires/computer-cables/usb-cables/?applied-dimensions=4290466079,4290466101)**:** This connector is mostly used for connecting printers, scanners, and other peripheral devices to computers. It has a square shape with bevelled corners.
- [**Mini-USB:**](https://uk.rs-online.com/web/c/cables-wires/computer-cables/usb-cables/?applied-dimensions=4290466076,4290466099,4290466105) Mini-USB connectors were popular in the past but are now less common. They come in two forms: Mini-A and Mini-B. These cables were commonly used for connecting digital cameras, older smartphones, and other portable devices.
- [Micro-USB:](https://uk.rs-online.com/web/c/cables-wires/computer-cables/usb-cables/?applied-dimensions=4290492719,4290466040,4290466095) Micro-USB connectors are smaller and more commonly used in various devices, including smartphones, tablets, digital cameras, Bluetooth speakers, and many other portable devices. They are reversible, allowing insertion in either orientation.
- [**USB Type-C**](https://uk.rs-online.com/web/c/cables-wires/computer-cables/usb-cables/?applied-dimensions=4290466041,4290471157,4290471158)**:** USB Type-C is a newer and versatile connector that is becoming increasingly popular. It is reversible like Micro-USB but has a smaller form factor. USB Type-C cables can be used for charging devices, data transfer, and connecting various peripherals. They support faster data transfer speeds and can deliver more power.
- [**USB to DC**](https://uk.rs-online.com/web/c/cables-wires/computer-cables/usb-cables/?applied-dimensions=4290466102,4290466079,4290471157,4290099318)**: **These USB Power Cables enable power to an external DC devices through an available USB port from your desktop, laptop computer or adjusted mains outlet.

USB Extension Cables | RS

<p>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.</p><h2>Where are USB extension cables used?</h2><p>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.</p><p>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.</p><h2>How long are USB extension leads?</h2><p>USB extension leads are available in various lengths to suit a range of applications and can vary from around 0.5m to 35m.</p><h2>Types of USB connectors:</h2><ul><li>USB A</li><li>USB B</li><li>Mini USB B</li><li>Micro USB B</li></ul><p>Note: Some USB connectors are available in both male and female (plug or socket) versions.</p><h2>IP Ratings for USB Extension Cables</h2><p>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.</p>

<p>Lightning cables are small 8-pin connectors used with Apple hardware, including iPhones, iPads, and iPods, to connect them to host computers and other devices, and are also used as charger cables. Many companies have created their own lightning cables, but Apple have held the 'Lightning' trademark since 2012.</p><p>When they were introduced to Apple's range of accessories in 2012 in combination with the port appearing for the first time in their devices, lightning cables replaced their 30-pin predecessors as a denser but smaller and more flexible connector that measures just 6.7mm x 1.5mm. With a symmetrical design on either side, the male lightning connector can be inserted into the female port in either orientation as the processors in these products are designed to route data and power correctly no matter which way up the connector is inserted. This helps to prevent damage to the female port that could be caused from incorrect insertion, and there are various adaptors available to allow for wider compatibility, such as those for audio jacks.</p><h2>What are lightning cables used for?</h2><p>Lightning cables are multifunctional and can not only provide power transfer (to charge the device) and data transfer (such as loading images to a host computer), but can also transmit audio when headphones with a lightning port are connected to the chosen device.</p>

<p>USB cables - also known as Universal Serial Bus cables - provide connection from computers and other host devices to peripherals, such as keyboards, printers, network adaptors and pointing devices. They are also used to provide electrical power to portable devices, such as mobile phones, portable media players, or handheld games consoles via a wall adaptor or computer.</p><h2>What are USB A to USB C cables used for?</h2><p>USB C connectors are thin, rectangular connectors and are recognisable as smaller than USB A and USB B connectors. They are similar in size and shape to Lightning cables, although USB C connectors are hollow and have their pins on the inside, whereas Lightning connectors are solid with the pins visible on the top and bottom of the connector. USB A to USB C cables are commonly used as charger cables for many electronic devices and will be familiar to many as mobile phone chargers, handheld games console chargers, and even charger/power cables for some models of laptops or notebooks.</p>
