Datalogic S50 series offers all optical functions within a M18 housing. With the universal sensing functions of proximity, polarised retroreflex and through beam, which are also available with class 1 laser emission, as well as the more advanced functions of background suppression, background/foreground suppression, analogue displacement, contrast and luminescence, the S50 really is one housing for all applications. The S50 setting is carried out-by either by potentiometer, which is sealed to IP67, or using the patented EASYtouch push-button teach system, which gives rapid and precise automatic setting of the switching points.
