The SICK WTB27-3R2611 is a diffuse photoelectric sensor in a block housing, with a detection range spanning 30 mm to 1.6 m. That range covers short- to medium-distance presence detection — think package presence on a conveyor or part-in-place on a palletizer — without needing a separate reflector or receiver. The diffuse mode means the sensor sees the target's own reflected light, so mounting is single-ended: one device, one cable run.
