Balluff BKT 21M-002-P-S4 Contrast sensor, PNP, NO/NC Part number BKT000Y

The BKT 21M-002-P-S4 is a contrast sensor with a PNP output configurable for normally open or normally closed switching. It detects contrast differences on a sensing surface using a glass front element, housed in a powder-coated aluminium and zinc die-cast body rated IP67 for use in demanding industrial environments. Connection is made via an M12x1 four-pin male connector, with mounting via M4 screws, and it operates from a 10-30 VDC supply. Typical applications include automation and packaging lines where reliable detection of printed marks or edges is required.
