HIKROBOT MV-CH250-90XM-C-NN — Area Scan Cameras

The MV-CH250-90XM-C-NN is the monochrome 25 MP model in the CoaXPress family of the CH series, and among its siblings on this page it carries the strongest image-quality figures: 41 dB SNR and 65 dB dynamic range. The Gpixel GMAX0505 global-shutter CMOS sensor offers 5120 × 5120 pixels at 2.5 μm × 2.5 μm, delivering 41.5 fps in Mono 8 over the CXP-6 interface. A 2.0×–5.0× gain range and an exposure window from 13 μs to 10 seconds give it room to work in low-light measurement setups as well.

Data travels at CXP-6 speed over a DIN-connector CoaXPress link into a CoaXPress-compliant frame grabber; the CXP-1 link can also carry power via PoCXP, or a 9–24 VDC external supply may be used, with consumption typically 7.0 W at 12 VDC. The 12-pin P10 connector provides one opto-isolated input (Line 0), one opto-isolated output (Line 1), one bi-directional non-isolated line (Line 2) and RS-232. The fanless design fits a compact 50 mm × 50 mm × 45 mm C-mount body weighing roughly 207 g, and the camera conforms to the CoaXPress protocol and the GenICam standard.

Specifications

Key features

• Resolution of 5120 × 5120, pixel size of 2.5 µm × 2.5 µm.
• Adopts global shutter CMOS sensor to provide high dynamic range, SNR, and high-quality image.
• Adopts CXP-6 interface to transmit data.
• Compatible with CoaXPress Protocol and GenICam Standard.

Where it is used

The 41 dB SNR and 65 dB dynamic range pay off in monochrome applications where low-contrast defects must be separated from noise: semiconductor and wafer surface inspection, AOI on dense PCBs, dimensional measurement of precision mechanical parts and fine scratch detection on glass or metal surfaces. The compact fanless body makes it easy to place the camera on optical benches or in enclosed measurement stations without introducing vibration.

Suitability depends on working distance, field of view, target characteristics and positioning. Selection is assessed on a per-project basis.
