HK12NA Reflex Sensor with Background Suppression
Available from stock
Added to Your Cart:
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.
This product has been discontinued, but is still available as a spare part.
