The Keyence CV-3501P is a powerful digital image sensor/controller designed to deliver advanced image processing and inspection in demanding industrial environments. With support for up to four cameras using the CV-E300 expansion unit, the controller accommodates both color and monochrome cameras, enabling flexible configurations. Its 2-megapixel resolution (1600 √ó 1200 pixels) ensures detailed image capture for high-accuracy inspection tasks, while 1-megapixel and normal modes provide optimized performance for less demanding applications.

One of the standout advantages of the CV-3501P is its extensive suite of inspection tools. Operators can deploy features such as pattern search, ShapeTrax, blob detection, stain analysis, edge position measurement, OCR (character recognition), and intensity or color inspection. With support for a wide range of geometric and statistical functions, the unit enables precise measurement and classification of parts, ensuring consistent quality across production lines. The ability to configure up to 128 measurement windows per program and apply multiple mask areas makes the system adaptable to complex inspection scenarios.

The controller also excels in program management and memory capacity. It can store up to 1000 registered programs and 1000 screens per program, with approximately 60 MB of internal memory for settings and image data. For larger-scale requirements, it supports external memory cards (up to 1 GB), allowing storage of compressed images, statistical data, and test logs. The screen save and hold image functions enhance traceability, while advanced statistical tools enable operators to analyze up to 20,000 data points for trends and deviations.

Connectivity is another core strength of the CV-3501P. The unit is equipped with 27 PNP control outputs, a PNP comparator output, and communication ports including RS-232C, Ethernet (100BASE-TX/10BASE-T), and USB 2.0 high-speed. It also supports PLC link functions with major brands such as Keyence, Mitsubishi, and Omron, ensuring seamless integration into existing control systems. A monitor output (SVGA 800 √ó 600) provides clear real-time display, while the dual-language interface enhances usability in international applications.

The CV-3501P is designed for reliable industrial use. It operates with 24 VDC ±10% power supply and consumes up to 2.8 A when four cameras are connected. Its rugged design withstands environmental conditions such as 0 to +50 °C operating temperature, 35–85% RH humidity, and vibration resistance across three axes. At 950 g, the controller is compact enough for easy installation without compromising durability.

In summary, the Keyence CV-3501P combines multi-camera adaptability, powerful image processing tools, high storage capacity, and versatile connectivity. It is an ideal solution for manufacturers seeking to enhance accuracy, traceability, and efficiency in automated visual inspection systems.
