Sensor Instruments SI-COLO2-LWL Color Sensor Module

The SI-COLO2-LWL color sensor module from Sensor Instruments is a fiber-coupled color inspection device designed for inline quality control and color recognition in automated production lines. In the SI-COLO2-LWL-SP configuration, it uses a reflex optical fiber together with a mounted KL-3 optical unit to project a color-detection spot with a diameter of less than 1 mm at roughly 15 mm from the front-end, enabling precise, small-area color checks. The coaxial arrangement of transmitter and receiver fibers tolerates distance fluctuations of several millimeters and remains largely insensitive to angular changes of the object being measured. A color memory capable of storing up to 15 colors supports repeatable teach-in and quick color identification across repeated cycles. Typical applications cited for this family include verifying the color sequence of cables at connectors, detecting color marks on rotated cosmetics pencils, and checking color consistency on differently printed packings in packaging or assembly contexts. The SI-COLO2-LWL line is documented by Sensor Instruments GmbH in Thurmansbang, Germany, reflecting its role as a dedicated color-inspection sensor tailored for industrial use.
