The S90 series, in a compact 41x49x15 mm metal housing, offers all the application and universal optic functions also with safety class 1 laser emission. The series includes polarized retro-reflective models with coaxial optics for the detection of reflective and transparent objects, background and foreground suppression versions, contrast sensor with white light emission for color mark detection, ultraviolet sensor for luminescent object detection. Basic models are available with class 1 laser emission for high-resolution detection.

The S90 models with universal proximity, retro-reflective and through beam optic functions have trimmer sensitivity adjustment. More sophisticated models are microprocessor controlled and offer the patent-covered EASYtouchTM setting procedure for rapid and precise automatic setting of the switching threshold, with remote control, keyboard lock and output delay activation functions.
