Reflex Sensor with Background Suppression
YN44PA3
- High Precision Background Suppression up to 400 mm
- Stainless Steel Plug (V2A)
- Switching Frequency: 600 Hz
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.
