SICK W12L photoelectric retro-reflective sensor

SICK W12L photoelectric retro-reflective sensor

The W12L product family comprises photoelectric retro-reflective sensors with a sensing range up to 12 m, and photoelectric proximity sensors with sensing distances up to 1.2 m. Reliable detection over large distances can just as easily be master as detection tasks in the near range. The extremely precise light spot produced by the class 1 laser light spot of the sensors also allows even filigree objects and features to be detected – even through very small holes or cutouts, depending on the mounting situation. In applications where objects with perforated, structured or uneven surfaces need to be detected, the LineSpot technology with its line-shaped light spot ensures an optimal detection reliability.
