S51 - M18 Photoelectric Sensor Basic Line - Datasensor

The S51 series offers the most cost-effective 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 EN60947-5-2 standard, having the normally open output which is activated in the light mode in the proximity models and in the dark mode in the retroreflex models. The output mode can be inverted using the dark/light selection input wire provided.
