The diffuse proximity model has a 10cm xed operating distance with a wide emission spectrum. Also available is a version with a 1 - 40cm adjustable operating distance. Standard retro-re ective models have an operating distance up to 4m while the polarized retro-re ective models, used for reliable detection of re ective objects, are tted with a sensitivity adjustment and have a 3.5m operating distance. The emitter and receiver models, used for longer operating distances, reach 18 meters. The S51 series sensors, with cable or M12 connector and PNP or NPN output, provide a 3-wire connec- tion con guration in compliance with the EN60947-5-2 standard. The normally open output is activated in light mode in proximity models and in dark mode in retro-re ective models. The output mode can be inverted using the dark/light selection input wire provided, making these extremely versatile sensors.
