Rolling buffer (5 measurements)
After an object has entirely left the light beam of the trigger zone, the distance that was
recorded during detection, is stored in a register as the measured distance to object. The
sensor has the capacity to store 5 measurements at the same time. Every new
measurement will erase the oldest (5
th
) value from the device. This functionality allows to
obtain accurate distance-to-target feedback as an added layer of intelligence, in addition to
the NO/NC switching output. Please refer to
