Baumer OADR 20I6 Series User Manual
What can you do if you have transparent, semi-transparent and highly reflective objects?
The measuring principle desires an object that reflects the light diffusely. Semi-transparent, transparent and
highly reflective objects do not have this feature.
 When measuring on semi-transparent objects, the light enters the object and so the measured distance is
larger than the actual distance is.
 Light will pass through a transparent object so a measuring signal is not available.
 A highly reflective object only has a direct reflection and it is not possible to work with it. For such an
application, ask the Baumer electric sales staff.
 measuring against such objects is only possible by placing a diffusely reflecting surface on the object
(sticker, etc.)
Semi transparent objects:
The light enters the object.
 The measured distance is
larger than the real distance
