# MER-031-860U3M

> The MERCURY USB3.0 series (MER-U3) camera is DAHENG IMAGING’s mature area scan industrial digital camera, featuring outstanding performance, compact design, and extremely low noise. The MER-031-860U3M/C camera is a monochrome/color USB3 Vision camera with the Onsemi PYTHON 300 CMOS sensor. Thanks to the extremely compact (29mm × 29mm × 29mm), robust metal housings and locking screw connectors, the MERCURY cameras can secure the reliability of cameras deployed in harsh environments. The MER-031-860U3M/C camera is powered over the USB interface. The MER-031-860U3M/C camera has opto-isolated I/Os. The GPIOs give MER-U3 maximum flexibility to adapt to specific needs. The camera has an outstanding price/performance ratio. The MERCURY family cameras are especially suitable for machine vision applications such as industrial inspection, medical, scientific research, education, security and so on.
