Sensor type and detection range
The SICK WTB16P-24161120A00 is a block-style background suppression photoelectric sensor with a detection range from 10 mm to 1 m. Background suppression means it measures the angle of reflected light to discriminate the target from the background at a set cutoff distance, so it ignores objects beyond that threshold. For a conveyor or pick-and-place station, that 1 m maximum gives you a working window for parts up to about that distance, with the suppression cutoff set within the first 10 mm to 1 m span.
