Q
Can detection take place when the object
is closer than the rated detection dis-
tance?
Yes.
The sensor emits an infrared beam, measures the distance to the person
(object) by means of the light reflected back, and determines whether or not
the object is within the detection distance.
However, with the exception of the non-sensitive zone in the immediate
proximity of the sensor where light reflected off the object cannot return to
the receiver lens, the sensor detects objects anywhere within the rated
detection distance.
