These sensors detect distance by measuring angles. They are particularly good at recognizing objects in front of any background. The color, shape and surface characteristics of the object have practically no influence on sensor switching performance.

  • Stainless steel housing
  • Adjustable switching distance
  • Electronic background suppression
  • Red light
