How large is the differential distance for Photomicro Sensors?
The distance depends on the model, but use the following values as a guide.
Slot-type Photomicro Sensors: Approx. 0.025 to 0.05 mm
(If the sensing object travels across the shorter side of the light emitting/receiving window.)
Reflective Photomicro Sensors: Approx. 0.2 to 0.5 mm
(If the sensing object travels parallel to the sensing surface.)
