Photoelectric - Tubular -S51
Photo-Electric Sensors, Retroreflex Polarized
The S51 series offers the most costeffective solution in M18 photoelectric sensors which is today improved thanks to the increase of the operating distances. The range includes the tubular metal housing as well as a brand news flat plastic housing which make installation. The tubular plastic
and metal models are both available with either axial or radial optics; in both cases the optic head and lenses do not protrude beyond the external 18 mm diameter of the sensor housing. The
diffuse proximity model presents a 10 cm fixed operating distance with wide emission spectrum and the another model with 1 - 40 cm trimmer-adjustable operating distance. Standard
retroreflective models have an operating distance up to 4 m whilst the polarised retroreflective models used for reliable detection of reflective objects are fitted with sensitivity adjustment and have a 3.5 m operating distance. The emitter and receiver models, used for longer operating distances, reach 18 meters.
The sensors of the S51 series, with cable or M12 connector and PNP or NPN output, provide a 3 wire
connection configuration in compliance with the EN 60947-5-2 standard.
