USB technology has been a crucial component in connecting our devices for data transfer and power. Among the various types of USB connectors, the USB-B cable plays a significant role in connecting peripheral devices like printers and scanners. While not as common as USB-A or USB-C, the USB-B connector is still widely used in specific industries for high-power and data-demanding tasks. In this guide, we will explore the USB-B cable’s features, its applications, and everything you need to know about this connector type.
What is a USB-B Cable?
A USB-B cable is primarily used to connect larger peripheral devices, such as printers, external hard drives, and certain scanners, to a computer. Unlike USB-A, which is often found on computers, USB-B is designed for devices that require higher power and a more stable connection for data transfer.
USB-B cables generally come in two versions:
- USB 2.0 Type-B: Used for slower data transfers with a maximum speed of 480 Mbps.
- USB 3.0 Type-B: Also known as “SuperSpeed,” it supports data transfer speeds of up to 5 Gbps, making it ideal for applications that require fast communication between devices.
