Daheng Imaging MER2-2000-19U3M-W90 20 MP USB3.0 Area-Scan Camera
20 MP USB3.0 mono camera with 90-degree angle lens mount for tight installations
Overview
The MER2-2000-19U3M-W90 is a monochrome MERCURY2 series USB3.0 Vision camera with a 1-inch Sony IMX183 rolling-shutter CMOS sensor and a 90-degree angle lens mount that lets the sensor face be mounted perpendicular to the data interface. It runs 19.6 fps at 5496 x 3672 and is powered over USB3.0 at 2.00 W. Opto-isolated I/O, programmable LUTs, binning, decimation and a 16 KB user data area support demanding inline inspection.
Key highlights
