Frequently Asked Questions
What are the limitations of conventional color mark sensors?
They can struggle with highly reflective glossy packaging or low-reflection packaging due to saturation, resulting in false detections.
How do the E3S-DC/E3NX-CA series address detection issues?
It provides high dynamic range and smart noise reduction, enabling stable detection of both glossy and colorful packaging without manual intensity adjustments.
Is this sensor suitable for diverse materials like aluminum or thin paper?
Yes, it can handle glossy aluminum vapor deposition material and is designed to facilitate the stable detection even with tilted workpieces.
