Keyence IV4 AI Vision Sensor | 1280x960 Wide FOV OK/NG Check

The Keyence IV Series (IV4, IV3, and IV2) redefines industrial inspection by integrating a high-speed camera, powerful lighting, and an AI-driven controller into a single compact housing. Designed for the 2026 smart manufacturing era, the IV4 series features advanced AI that automatically optimizes imaging parameters, ensuring stable OK/NG Inspection even with targets that have significant position shifts or surface variations.

Whether you are performing high-speed counting in electronics or presence detection in automotive assembly, the Wide Field of View (FOV) and self-learning algorithms eliminate the need for expert vision knowledge. With a 15-second setup time, the Keyence IV series is the ultimate "plug-and-play" solution for reducing defects and labor costs.

1. AI Auto-Recognition: No more manual threshold setting. Simply register 1-2 OK/NG samples, and the built-in AI handles the rest.
2. All-in-One Design: Integrated lens, lighting, and CPU. No separate PC or external illumination is required for most industrial scenarios.
3. Position-Free Detection: The Wide FOV allows for stable detection even when workpieces arrive at different angles or positions on the conveyor.
4. High-Speed Processing: The IV4 series supports up to 250 pieces per second, matching the speed of the fastest automated production lines.
5. Industrial Connectivity: Seamlessly connects via EtherNet/IP, PROFINET, or standard I/O to Siemens S7-1200 or Omron PLCs.

• Electronics & Semi: Detecting PCB component presence, polarity marking, and pin defects with sub-millimeter precision.
• Automotive Assembly: Verifying the presence of clips, O-rings, and screws, ensuring 100% assembly integrity.
• Food & Pharmaceuticals: Checking bottle cap tightness, label presence, and expiry date (OCR) legibility.
• Logistics & Packaging: Detecting box sealing status and sorting items based on shape or barcode patterns.

Q: What is the main difference between Keyence IV3 and IV4?

A: The IV4 series is the latest generation focusing on higher speed (250 fps) and more advanced AI learning tools, whereas the IV3 is renowned for its ultra-wide field of view at longer distances.

Q: Can I operate the IV4 sensor without a separate PC?

A: Yes. By using the IV4-H30 touchscreen controller, you can perform all setups, tool registrations, and monitoring directly on the line.

Q: How does the AI handle environmental light interference?

A: The built-in AI optimizes the integrated white LED pulse and exposure time to suppress ambient light, ensuring the Image Recognition remains stable even in varying factory lighting.

Q: Does it support barcode or OCR (Text) reading?

A: Yes. The IV3 and IV4 series have dedicated tools for 1D/2D code reading and alphanumeric OCR, making them ideal for packaging verification.

Q: Can I use one IV4 sensor to check multiple points at once?

A: Absolutely. You can set up to 128 different detection tools (Multi-Tool) within a single FOV to check multiple features on one workpiece.

Q: What is "Learning Mode" in the IV4-G series?

A: Learning Mode allows the sensor to "study" multiple OK samples to understand acceptable variations (e.g., slight reflections), significantly reducing "False NG" errors.

Q: Is the sensor rugged enough for oily or dusty environments?

A: The sensor heads are typically rated IP67, meaning they are dust-tight and can withstand immersion in water, suitable for most industrial floor conditions.

Q: How do I backup my IV series settings?

A: Settings can be saved to a standard SD card in the controller or uploaded to a PC via the free IV configuration software for easy line duplication.

Q: Does the IV4 support color-based inspection?

A: Yes, models with the "CA" suffix (e.g., IV4-500CA) feature high-resolution color CMOS sensors for color-sorting and defect detection.

Q: Can the IV series be integrated with a Siemens S7-1200 G2 PLC?

A: Yes. It supports PROFINET and EtherNet/IP for direct data exchange, allowing the PLC to trigger the camera and receive OK/NG results instantly.
