Quick Answer:
Yes. The same sensor family does edge and line/contrast guiding; order the white-light head for most line/contrast work (the light source is fixed at order).
Yes, the same sensor family does both. An infrared head handles edges and high-contrast printed lines; for most line and contrast work, order the white-light head. The light source is fixed at order. This dual capability reduces equipment cost and simplifies changeovers—operators don't need to swap sensors when switching between edge-guided and line-guided products.
