Reflex Sensor with Background Suppression
HK12NA
- Electronic Background Suppression
- Miniature Design
- Red Light
- Switching Distance Adjuster
These sensors are particularly well suited for recognizing objects in front of any type of background. The color, shape and surface characteristics of the object have practically no influence on sensor switching performance.
