In the same way as for Diffusereflective Sensors, Limitedreflective Sensors receive light reflected from the sensing object to detect it. The optical system restricts the light emission and reception area, so only objects that are a specific distance (area where light emission and reception overlap) from the Sensor can be detected. In the figure on the right, the sensing object at (A) can be detected while the …
