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=40cm±5cm 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
