M18 photoelectric sensor series
November 2003
Sensors & Transducers
The S51 series offers a very cost-effective solution for object detection in all industrial automation applications. The standard M18x1 tubular plastic housing is 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.
There are two models of the diffuse proximity function: one with 10 to 100 mm fixed operating distance and the other with 10-300 mm adjustable operating distance. Standard retroreflective models have an operating distance up to 3 m whilst the polarised retroreflective models used for reliable detection of reflective objects are fitted with sensitivity adjustment and have a 2 m maximum operating distance. The emitter and receiver models, used for longer operating distances, reach 12 m.
The sensors of the S51 series, with cable or M12 connector, provide a 3-wire connection configuration in compliance with the EN60947-5-2 standard, having the normally open output present on pin 4, regardless of optic function. The output mode can be inverted using the dark/light selection input wire provided.
