*2 We ship the device after the following adjustment : Output switching distance L=24cm±3cm 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
