USB (Universal Serial Bus) connectors are electrical connectors with a flat, typically rectangular-shaped connection into which a corresponding plug fits. They're commonly found on computers, hubs, or peripherals such as printers, scanners, audio interfaces, and test equipment.

USB connectors have many variations and different speeds; however, they all have the same function. Typically, the job of a USB is to transport data and power to a device through various communication protocols. Our USB connectors can also be paired with a variety of [USB accessories](https://au.rs-online.com/web/c/connectors/usb-d-sub-computing-connectors/usb-connector-accessories/) to further enhance your options.

## **How Does a USB Connector Work?**

USB connectors facilitate communication between devices by transmitting data and power through various communication protocols. They can be directly connected to PCBs (printed circuit boards) or used to create [USB cables](https://au.rs-online.com/web/c/cables-wires/computer-cables/usb-cables/). Additionally, USB connectors can be integrated into panel mount configurations, providing convenient access points for connecting and disconnecting devices.

## **Types of USB Connectors**

USB connectors are available in various types, each with its own distinct characteristics and applications:

- **USB Type A Connectors:** The most common type, widely recognised for its flat, rectangular shape. Primarily found on host devices like computers and hubs, USB A connectors are known for their durability and ease of use.
- **USB Type B Connectors:** Typically used for connecting peripherals such as printers, scanners, and external hard drives. USB Type B connectors feature a square shape with bevelled edges.
- **USB Type C Connectors:** The latest generation of USB connectors, offering reversible plug orientation, faster data transfer speeds, and higher power delivery capabilities. USB C connectors are becoming increasingly prevalent in modern devices.
- **Mini USB Connectors:** A smaller version of the USB connector, often used in older portable devices like digital cameras and MP3 players.
- **Micro USB Connectors:** Even smaller than mini USB connectors, micro USB connectors were commonly used in smartphones and tablets before the widespread adoption of USB C.

Each of the USBs comes in various speeds, types, and communication protocols they can be used with. When [choosing the right connector](https://au.rs-online.com/web/content/discovery/ideas-and-advice/choosing-the-right-usb-connector) for you, it's essential to consider:

- **Mounting type:** Whether you need a straight PCB connection or a cable-mounted device.
- **Gender:** USB ports come in either a female or male gender.
- **USB version:** The USB version defines the shape of the USB. USB C is the most up-to-date and fastest connector to date.

## **Different Mounting Types for USB Connectors**

You can choose from a range of mounting options to suit different applications and installation requirements:

- **Panel Mount USB Connectors:** Designed for secure installation on panels or enclosures, providing convenient access points for connecting devices.
- **Surface Mount USB Connectors:** Surface-mounted directly onto PCBs, offering a space-saving solution for compact devices.
- **Through-Hole Mount USB Connectors:** These connectors have leads that pass through holes in the PCB, providing a robust and reliable connection.
- **Cable Mount USB Connectors:** Designed to be attached to the end of a cable, enabling the creation of custom USB cables for specific applications.

## **Comparison of USB Versions**

USB technology has evolved over the years, with each new version offering improvements in data transfer speeds and power delivery capabilities. Here's a comparison of common USB versions:

- **USB 2.0:** Offers data transfer speeds up to 480 Mbps. Widely compatible with older devices.
- **USB 3.0:** Provides significantly faster data transfer speeds up to 5 Gbps. Backwards compatible with USB 2.0.
- **USB 3.1:** Further enhances data transfer speeds, reaching up to 10 Gbps. Includes variations like USB 3.1 Gen 1 (same as USB 3.0) and USB 3.1 Gen 2 (10 Gbps).
- **USB 3.2:** The latest generation, with speeds up to 20 Gbps. Includes variations like USB 3.2 Gen 2x2 (20 Gbps).

## **Industry Standards and Compliance**

USB connectors adhere to industry standards to ensure compatibility and interoperability across devices.

- **USB-IF:** The USB Implementers Forum (USB-IF) defines and maintains the USB specifications, ensuring standardisation and compliance.
- **Industry Adoption:** Various industries have adopted specific USB types based on their needs and standards. For example, USB-C has become the standard for smartphones, laptops, and even automotive applications due to its versatility and high-speed capabilities.

## **Industry Applications**

USB connectors are used in various industries, facilitating connectivity and data transfer in a multitude of applications:

- **Discrete Manufacturing:** Used in industrial automation systems, connecting peripherals, programming devices, and human-machine interfaces (HMIs).
- **Process Manufacturing:** Enable data acquisition, process monitoring, and control in process automation systems.
- **Energy & Utilities:** Facilitate communication, data logging, and control in smart grids, renewable energy systems, and power monitoring equipment.
- **Facilities & Intralogistics:** Used in building automation systems, security systems, and data centres for connecting and managing various devices.
