 USB CABLE

 USB stands for Universal Serial Bus. USB replaces all the different kinds of serial and parallel port connectors with one standardized plug and port combination. With USB-compliant PCs and peripherals, you just plug them in and turn them on. USB makes the whole process automatic. It's like adding instant new capabilities to your PC.  
  　

　

USB A/B TYPE

USB CABLE-highlight

  • Supports up to 127 external PC peripherals.

  • Industry standard will take the guesswork out of expanding PC functionality.

  • Up to an incredible 12 Mbps data transfer rate.

  • Cost effective universal connection helps reduce the cost of owning & using PCs & IntelliStations.

USB CABLE-feature

The full speed USB bandwidth (up to 12 Mbps) can support a wide range of multimedia and telephone USB devices. The low-speed bandwidth (up to 1.5 Mbps) can support low-cost, low-end devices such as USB keyboard and mice. Simultaneously, USB ports will support both full-speed and low-speed devices .

USB CABLE-construction

Two types of plugs and receptacles are specified for USB: A Type and B Type. The shielded cable connector will be 4 positions with gold-plated contacts---2 for single on 2mm centerline, 2 for power on 2.5mm centerline.

A Type Plug used for those devices (keyboard, mouse, joystick etc...) on which the external cable is permanently attached.

USB A Type Plug

B Type Plug used for those devices (printer, scanner, modem etc...) that requires an external connector, so that USB cabling is detachable.
