Triangulation sensor (BGS) OBT20-R2-E0

OBT20-R2-E0
  • High-performance miniature photoelectric sensors
  • 45° cable outlet for maximum mounting freedom under extremely tight space constraints
  • Improvement in machine availability with abrasion-resistant, antistatic glass front
  • Extremely small light spot for very high switching point accuracy
  • Highly visible light spot, even on dark materials
  • Precision detection of objects within the defined sensing range, almost irrespective of the color

Function: OBT20-R2-E0

The nano sensor has been developed for a broad range of applications. It offers excellent durability and is exceptionally easy to install. The housing is compact and, with its 45° cable outlet, can be installed in the smallest spaces. New functional principles and functionality open up a range of new options. The abrasion-resistant lens allows long operating times close to the moving object.
