Industrial vision for faster and more complex applications

On high-speed production lines, a vision system must do more than just capture a good image. It must process data quickly, maintain consistent results, and adapt to real-world variations in parts, surfaces, and lighting conditions.

The Cognex In-Sight 3800 is built for this type of environment. The system offers resolutions of up to 16 MP, fast processing, and a combination of AI tools and classic vision functions, all in a platform designed for demanding industrial inspections.

Integrated AI for detection, classification, and recognition

The ViDi EL Segment, ViDi EL Classify, and ViDi EL Read tools help address applications where parts do not always look identical or where defects are subtle. The system can detect anomalies, classify products, and read difficult text, including on reflective or low-contrast surfaces.

High performance for high-speed lines

The In-Sight 3800 is designed for high-speed processing and can handle high-volume production applications. In practice, this makes it ideal for presence checks, measurements, counting, barcode reading, robotic guidance, and quality inspections where decision time is critical.

Clearer images with built-in lighting and HDR+

The integrated multicolor backlight and high-brightness lighting options allow you to optimize contrast directly from the app. HDR+ technology helps produce more balanced images with greater detail, even in situations involving shiny surfaces, dark areas, or high contrast.

Flexible platform for industrial integration

The system includes two Ethernet ports, a USB-C interface, and support for industrial protocols such as PROFINET, EtherNet/IP, SLMP, and ModbusTCP. Configuration is performed in In-Sight Vision Suite, with options for both quick applications using EasyBuilder and complex applications using the spreadsheet interface.

Who is it suitable for?

factories with high-speed production lines and demanding inspection applications
manufacturers who require high resolution and a wide field of view
Applications for defect detection, classification, measurement, and OCR
processes where lighting and contrast directly affect the quality of the inspection
system integrators who need a flexible, scalable, and industrial-grade platform
