7.3.3 Response delay
The response delay is equivalent to the time elapsed between the triggering of the measure-
ment (internal signal) and the change in the measured value at the output.
The duration of the response delay depends on the exposure time. The sensor automatically
adjusts its exposure time to the object to be measured in order to always receive an optimum
light quantity and thus achieve a sufficient exposure reserve. The exposure time depends on
the properties of the measured surface (color/structure, etc.) and the alignment of the sensor to
the object to be measured. Dark objects to be measured reflect less light and thus need longer
exposure times than light-colored objects; the response delay increases.
