Overview
The Sick WL260-S230 is a compact photoelectric retro-reflective sensor engineered for industrial automation and motion control systems. Featuring a dual-lens design with visible red LED light source, this sensor combines versatile AC/DC supply compatibility (12–240V) with dependable switching performance. The retro-reflective principle enables accurate object detection without requiring separate receiver optics, making it ideal for straightforward installation in conveyor systems, packaging lines, and gate detection applications.
