This 30cm USB3 cable with USB3 A connector and USB3 Micro-B connector is designed for applications that require a short USB3 cable, like embedded solutions. It offers an additional JST connector where 5V can be extracted from the USB bus to provide power to external electronics. This can be used for example to power LEDS. Please note that the maximum power that can be extracted from the USB BUS is 5V @ 400mA = 2Watt. The remaining USB power is required for the industrial vision camera.
