Whether you are an office manager trying to set up a co-working space or a floor manager looking to accommodate new manufacturing equipment, USB cables can come in handy.

    In this guide, we will go through everything from the various types of USB cables available and their different applications to factors to consider before making a purchase.

    What are USB cables?

    USB cables, an abbreviation of Universal Serial Bus cables, are some of the most popular cable types available due to their ease of use, low cost of implementation, and compatibility with many operating systems and platforms. They are often used to connect a plethora of electronic devices to a computer or each other. USB cables were developed in the 1990s to help simplify the connections between computers and peripherals such as printers, keyboards, cameras, and more.

    How do USB cables work? A USB cable typically has four different wires that correspond to different colours. The green and white wires carry data, while the black and red wires power the cable. More specifically, the red wire acts as the positive wire and carries five volts, while the black one is the negative wire – also known as the ground wire.

    Types of USB cables Each USB cable is designed with its own specific purpose and device compatibility. If you are looking to select the right cable for your business needs, the first thing to do is to understand the different types of cables available out there. Below are a few commonly used USB connection types.

    USB A (type A) This is the most common USB cable, and it has a rectangular shape. It is roughly 1.4 cm (9/16 in) in length and 0.65 cm (1/4 in) in height. These USB extension cables are typically used for connecting devices such as laptops, computers, keyboards, power adapters, mouses, and more, and it is great for setting up an office. USB sticks often feature USB A connectors as well. Type A ports and cables are compatible with all USB versions, from USB 1.0 to the latest standard.

    USB B (type B) This type of USB cable is less common than type A cables. Type B cables are instead almost square and are mainly used to connect scanners, printers, routers, game consoles, and other periphery devices to computers. Type B cables and ports support nearly all versions of USBs, from USB 1.1 to USB 3.1. That said, type B cables are becoming less common as the size of electronic devices is shrinking.

    USB C (type C)

    The Type C USB cable is a versatile and newer cable that is becoming more popular. With dimensions of 0.84 cm by 0.26 cm, this new type of cable is designed to work with smaller ports to help support thinner forms of electronic devices. These cables are reversible, meaning they allow insertion in either direction. Type C cables and ports support various protocols in addition to carrying HDMI and DisplayPort signals. They are commonly found on laptops, charging devices, laptops, as well as docking stations and adapters. They aim to support faster data transfer speeds, in addition to delivering more power to devices.

    Mini USB Mini USB connectors were once popular but are now less common. They come in two categories – Mini A and Mini B. These cables were often used to connect older smartphones, digital cameras, and other portable or handheld devices.

    Applications of USB Cables

    USB cables have become ubiquitous in the modern world, with plenty of industries and sectors making use of them, from manufacturing to finance and technology. USB cables play a vital role in facilitating data transfer, efficient operations, and connectivity, allowing users to stay connected. Below, we have listed some key applications of USB cables.

    Data transfer USB cables enable users to transfer data between various electronic devices, such as industrial equipment, computers, laptops, smartphones, servers and more. This is important for businesses as they often require the seamless transfer and synchronisation of data, documents, and files to ensure efficient and productive collaboration and workflow, especially between various teams.

    Device configuration When it comes to businesses, USB cables help to play an important role in managing and configuring devices in a variety of sectors and industries. These cables allow for efficient firmware updates, device setup, and any other configuration changes. This contributes to more streamlined and productive operations for a business, which can lead to improved performance in the long run.

    Point of Sale (POS) systems A Point of Sale (POS) system is both software and hardware that allows businesses to keep track of sales and accept payments. USB cables are used in POS systems in restaurants, retail brick-and-mortar stores, and other service establishments. This is because these cables assist with connecting cash registers, barcode scanners, receipt printers and card readers, to make sure transactions are seamless.

    Medical devices The medical and healthcare sector also makes use of USB extension cables. This is to help connect diagnostic equipment, medical devices and patient monitoring systems to computers and central databases. This way, healthcare establishments can collect, analyse, and share data, which aids in making more accurate diagnoses when it comes to patient care.

    Industrial automation As market demands grow, more businesses are turning to automation to help speed up their workflow and processes. This usually entails the use of robots and other industrial machines. To get them up and running smoothly, USB cables are used to connect sensors, machinery, robots, and control systems to central computers. This helps overseers to monitor the automation process in real time, as well as collect data that could assist with the production process.

    Charging solutions USB cables are often used to charge devices such as tablets, smartphones, Bluetooth speakers, battery packs, smartwatches, and other electronics. This is essential for most businesses nowadays, as cables are used to power devices in conference rooms, workstations, and other places throughout the workplace.

    Audio and video connectivity Finally, USB cables are used to transmit video and audio signals. For instance, businesses can use USB cables to connect webcams and digital cameras to computers, which enables video conferences, video recording, live streaming and more. This is essential for businesses that have teams that work in various locations and need to collaborate often, or if they need to meet and work with overseas clients. USB cables can even be used to help display multimedia presentations and demonstrations. These can enhance conferences, sales pitches, and online trade shows.

    Factors to consider when choosing a USB cable

    With so many options on the market, picking the right USB cable for your operations is crucial to streamline your workflow. This process involves considering several important factors, such as data transfer speed, cable durability, compatibility and more. Here are several key factors to keep in mind when picking a suitable USB cable.

    USB standard and connector type As mentioned, USB cables come in various types, such as USB A, USB B, USB C, micro-USB, and more. Connections also come in different editions, ranging from USB 1.0 to USB 3.0. Therefore, buyers must pick a cable that is compatible with their devices.

    Cable length Cable length is another important consideration buyers should keep in mind. It is recommended buyers pick a cable that is long enough to suit their needs. For most desk use, a 1.2m cable should be long enough for various applications. That said, some people may consider buying a longer cable, especially if they need to connect devices that may be further apart. That said, very long cables also tend to suffer from signal loss.

    Data transfer speed It is vital to select a USB cable that supports the desired data transfer speed. While for most situations USB 2.0 is fast enough, this may not be enough for certain applications. For instance, a videographer or video editor may require a cable that has a faster transfer speed. USB cables come in different generations, with each offering varying data transfer rates.

    Power Delivery Capacity For those who are looking to use a cable for charging purposes, they should check if the cable supports Power Delivery (PD). This is because PD-enabled cables can deliver higher power levels to electronic devices, meaning devices are charged at a faster rate.

    Cable durability and quality A good quality USB cable should be made using durable materials and can last for a long time. This means looking for elements such as bend and braiding protectors that will ensure a cable can withstand multiple uses. Another element to look out for is a cable’s thickness. This is because how long a cable is and how well-protected it is will determine its lifespan. Cheaper cables tend to use thinner wires to save on costs, but this also makes them break and fray more easily. Conversely, more expensive cables tend to be thicker and better protected.

    Compliance and certification Certifications tend to be a good indicator of quality, as this means the USB cable complies with some form of regulation. As such, buyers should consider looking for USB cables that are certified by standard organisations, for example, the USB-IF (USB Implementers Forum). This way, buyers can be sure that the cables adhere to safety and quality standards.

    Application-specific requirements

    Consider the purpose of buying the cable. What is the cable going to be used for? Will it be used to charge devices, transfer data, or connect to another device? Different applications will have different requirements, such as higher data speeds or different connector types.

    Brand and supplier reputation

    Buyers should opt for reputable brands that are known for producing, manufacturing, or supplying high-quality USB cables. Trusted brands such as RS Components often prioritise high-performance standards and quality control. Some brands also provide USB connector accessories that can help secure the lifespan of USB connectors.
