Industrial QLA-074050-66 Machine Vision Ring Light

Omron Automation and Safety CCS-QLA-074050-66 is a low-angle machine vision ring light designed to deliver oblique illumination around a camera lens. The unit features a red LED emission with a 74 mm outer diameter and a 50 mm inner diameter, configured for 24 V DC operation, and is RoHS compliant. As part of Omron’s vision-lighting lineup, this ring light provides consistent illumination for close-range inspection tasks, helping to reveal fine details on small, reflective surfaces without requiring a bulky lighting setup. Its 74 mm footprint suits compact vision systems and tight automation cells, making it a practical addition for applications such as PCB and connector inspection, small-part feature imaging, and other tasks where red illumination enhances contrast in grayscale or color imaging. By surrounding the lens with light, the QLA-074050-66 aims to produce uniform brightness across the field of view, improving edge detection and texture cues in challenging lighting conditions on dark or textured materials. This specific model is widely cited in machine-vision lighting inventories as a dedicated 74 mm red low-angle ring light, reinforcing Omron’s role in providing reliable, purpose-built illumination for imaging systems.
