The setting of the switching threshold is carried-out automatically by simply pressing a push-button or dynamically during label (or other reference) movement. The SR21-IR model with infrared emission is ideal for label or hole detection on continuous surfaces, while the SR21-RG model with double red or green emission suits colour print register mark detection on transparent films for automatic packaging.
