AI-Powered Detection
Traditional sensors fail when target colors vary slightly or positions shift. The IV4 uses AI to "Learn" multiple good images, creating a robust model that accepts natural process variations.
Auto-Learning: Just register OK and NG products.
Shape & Color: Detects presence based on multiple attributes.
Internal Light: High-intensity LED ring handles contrast.
