Measuring distance
LK-031/036/081/086/501/503
To measure the thickness of a moving object, place the target close to
the reference position where the spot diameter is smallest. This assures
the most stable detection.
Target shape and recommended setting
The LK series is less affected by the sensor head orientation by
employing the CCD as the light-receiving element. For the following
applications, however, mount the sensor head with the recommended
orientation, if possible.
