The DS35-B15821 is a block-style background suppression distance sensor with a detection range from 50 mm to 3.1 m and IO-Link communication. The background suppression means it measures distance to the target and ignores objects behind the set cutoff — useful on conveyors or packaging lines where the belt or a backstop could false-trigger a standard diffuse sensor. The 50 mm minimum detection lets it see targets close to the faceplate, so it fits in tight machine envelopes without a dead zone.
