These sensors detect the human body via the area reflection system.
The triple-angle distance measurement configuration makes it difficult
to be affected by the color (reflection ratio) of the detection object.
This is the high-precision distance measurement method used in the
auto-focus systems in cameras.
The system is configured so that the received light spot comes almost the center
of the photo detectors when if a human body is located at the detection distance L.
The system determines whether the body is farther (L+
the position of the received light spot.
The sensor sends out a ray of light toward the human body, then uses the reflect-
ed light to measure the distance and determine whether there is a person within
a given distance of the sensor. If the sensor decides that there is a person within
the given distance, it sets an output non-contact switch to ON.
