Balluff BOS 18K-1-A2-20-02 Photoelectric Sensor is a cylindrical Balluff sensor in the BOS 18K family, engineered for non-contact object detection in industrial automation. The 18K family uses an 18 mm diameter housing, and the -1-A2-20-02 suffix identifies this specific model within the BOS 18K lineup. Depending on the exact sub‑variant, BOS 18K devices support common photoelectric configurations such as diffuse-reflective, retro-reflective, and through-beam operation, with standard connection options including cable or M12 connectors and electrical characteristics defined by the particular variant.
