Reflex Sensor with Background Suppression
HK12PCT7
  • Electronic Background Suppression
  • Miniature Design
  • Red Light
  • Teach-In, external Teach-In, RS-232 Interface
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.
