1/2/2024 0 Comments Usb connector types![]() DisplayPort and Thunderbolt 3 are also supported via Alt Mode.īackward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3: USB4 maintains compatibility with previous versions of the USB specification and, thanks to its Thunderbolt 3 foundation, supports TB3 Alt Mode too. Multiple Data and Display Protocols: USB4 supports USB 3.2, PCIe and DisplayPort 1.4a through a technique called protocol tunneling. They can optionally support 40 Gbps (4.8 GB/sec) if they use the shorter 0.8 meter Gen 3 cable. Up to 40Gbps Data Transfer Rate: USB4 devices are required to support 20 Gbps (2.4 GB/sec). The USB4 protocol requires a USB-C to USB-C cable. USB 4 (officially "USB4" without the space) is an important update, not only for the new capabilities it offers but because it helps to resolve the confusion over USB 3.x naming and, for the most part, it gives users a predictable and consistent experience. Screw lock Micro B connectors are often used in cabling to ensure secure interconnection. With the growing need of higher data transfer rates, more industrial applications such as Machine Vision and 3D imaging are starting to implement USB 3.0 Micro B into their system designs. However devices with USB 3.0 Micro B receptacle can accept mating with previous USB 2.0 Micro B male plug. USB 3.0 Micro B connectors are found on hard drives, digital cameras, cell phones, and other USB 3.0 devices.Ī USB 3.0 Micro B male connector cannot be plugged in to a USB 2.0 B socket due to its plug shape change. USB 3.0 A to Micro B Panel Mount CablesĪlso referenced as the SuperSpeed Micro USB B connector, this connector stacks five more pins on the side of the USB 2.0 Micro B connector to achieve the full USB 3.0 standard data transfer speed.USB 3.0 connectors are often in blue color or with "SS" logo to help distinguish them from previous generations. USB 3.0 connector is designed to support 5Gbps bandwidth "SuperSpeed" data transfer, whereas, lower data rate can be transmitted with backward compatibility to USB 2.0 ports. However, USB 3.0 Type A processes additional pins that are not in the USB 2.0 A Type. Inheriting the same design to the A-Type connector used in USB 2.0 & USB 1.1 application, USB 3.0 A is also provides a "downstream" connection that is designed for use only on host controllers and hubs. USB 2.0 A Female to Crimp Housing Cables. ![]() ![]() ![]() Be aware that typical A-A cables are not intended for connection between two host computers or computer to hub. ![]() Though not that common, USB A male to A male cables are used by some implementers to make connections between two USB A style female port. As such, it is important to remember while purchasing USB cables it is safest to make sure at least one of the plugs is a USB A. This is because USB host will supply a 5V DC power on the VBUS pin. USB-A socket is designed to provide a "downstream" connection intended for host controllers and hubs, rarely implemented as an "upstream" connector on a peripheral device. Also known as USB standard A connector, the USB A connector is primarily be used on host controllers in computers and hubs. ![]()
