The Keyence CV-3501 is a powerful digital image sensor/controller designed to deliver precision inspection, measurement, and monitoring capabilities across diverse industrial applications. With support for both color and monochrome cameras, the controller offers resolutions up to 1600 √ó 1200 pixels (2 megapixel mode), ensuring sharp, accurate image processing for critical quality control. When expanded with the CV-E300 unit, the system can connect up to four cameras, making it highly adaptable for multi-point inspection systems in fast-paced production lines.

At its core, the CV-3501 provides a comprehensive set of measurement and analysis tools. These include position detection via pattern search and ShapeTrax, high-accuracy edge measurement and pitch analysis, blob detection for feature extraction, intensity inspection, stain analysis, and advanced geometric calculations. The system also supports OCR for character recognition and color processing functions (RGB and HSV) when connected to color cameras, allowing manufacturers to address both dimensional and appearance-based inspection requirements.

Memory and data handling capabilities are a defining feature of this model. The CV-3501 can register up to 1000 programs and 1000 screens per program, with a total internal memory capacity of around 60 MB. For long-term data storage and portability, it is compatible with memory cards up to 1 GB, capable of storing images, measurement results, statistical analysis, and communication logs. This scalability ensures users can manage both short-term and large-scale inspection projects efficiently.

The system offers excellent connectivity and integration options, supporting RS-232C, Ethernet, and USB2.0 Hi-Speed communication for numerical and image data transfer. Its PLC link function ensures smooth integration with major PLC systems, while SVGA monitor output provides clear real-time visualization. The ability to simultaneously manage communication ports makes it a flexible tool for connected, automated environments.

Durability is another advantage, with operational reliability ensured across temperatures of 0 to +50 °C (adjusted slightly when megapixel or four-camera configurations are used) and humidity levels of 35 to 85% RH without condensation. At only 950 g, the CV-3501 balances robust performance with a compact form factor.

In summary, the Keyence CV-3501 is a feature-rich image processing controller that combines high-resolution imaging, multi-camera adaptability, advanced inspection tools, and broad connectivity. This makes it an ideal choice for manufacturers looking to enhance accuracy, efficiency, and flexibility in visual inspection systems.
