L: Distance to a reflective object
*1 Type of reflective object: White paper (Gray chart R-27 made by Kodak, white surface, reflectance: 90%)
*2 Output switching distance is set at L = 80cm±10cm by a sensor.
*3 Range of measurable distances (Range of measurable distances of the optical system sensor)
*4 The output switching has a maximum hysteresis error. The distance characteristics specified by Vo should be
the distance at which the device switches from non-detecting area (output L) to detecting area (output H).
