Note) L : Distance to reflective object. *1 Using reflective object : White paper (Made by Kodak Co. Ltd. gray cards R-27 white face, reflective ratio ; 90%). *2 We ship the device after the following adjustment : Output switching distance L=24cm3cm must be measured by the sensor. *3 Distance measuring range of the optical sensor system. *4 Output switching has a hysteresis width. The distance specified by Vo should be the one with which the output L switches to the output H.
