Note) L:Distance to reflective object
*2 Using reflective object:White paper (Made by Kodak Co. Ltd. gray cards R-27 ⋅ white face, reflective ratio;90%)
*3 We ship the device after the following adjustment:Output switching distance L=15cm±2.5cm must be measured by the sensor
*4 Distance measuring range of the optical sensor system
*5 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
