Object to be measured 

6.4.1 

Object size 

The following requirements must be met so that the sensor can evaluate the object to be detected: 
The width of the object to be measured must not be smaller than the "smallest detectable object", and its 
height (step) must not be smaller than the "smallest detectable step".
