Adjustable-Field Sensing—Theory of Operaon
The A60AFV compares the reecons of its emied light beam (E) from an object back to the sensor’s two dierently-aimed detectors
R1 and R2 (see Figure 1 on page 2). If the near detector (R1) light signal is stronger than the far detector (R2) light signal (see object
A, closer than the
cuto distance), the sensor responds to the object. If the far detector (R2) light signal is stronger than the near
detector (R1) light signal (see object B, object beyond the cuto distance), the sensor ignores the object.
The cuto distance for these sensors is adjustable. Objects lying beyond the cuto distance are ignored, even if they are highly
reecve. However, it is possible to falsely detect a background object, under certain condions (see Background Reecvity and
Placement on page 4).

In the drawings and informaon provided in this document, the leers E, R1, and R2 idenfy how the sensor’s three
opcal elements
(Emier “E”, Near Detector “R1”, and Far Detector “R2”) line up across the face of the sensor. The locaon of these elements denes
the sensing axis (see Figure 2 on page 2). The sensing axis becomes important in certain situaons, such as those illustrated in Figure 7
on page 4 and Figure 8 on page 4.
