SICK CS81-P3612 Photoelectric Color Sensor Module

The SICK CS81-P3612 Color Sensor Module is a compact, diffuse-reflective photoelectric color sensor that uses RGB LED illumination to detect color on reflective surfaces up to 60 mm away. It emits RGB light at 640 nm, 525 nm and 470 nm, producing a 13 × 13 mm light spot, and fits in a metal housing measuring about 30.4 mm wide by 80 mm high by 53 mm deep; teach-in via a dedicated button enables static 1-point teaching for reliable color reference. The device provides a PNP switching output and draws roughly 100 mA at a supply range of 10–30 V DC, wired through a 5‑pole M12 connector; the official part number is 1028225. Common applications include color sorting, presence/verification checks on color-coded parts, and color-matching tasks on automated production lines that require a robust, RGB-based color sensor in a compact form factor.
