They feature an 18-mm stainless-steel housing with low-profile mounting that installs in spaces as small as 28 mm. Sensors offer prefixed sensing ranges, eliminating additional programming and setup. Units operate with a visible red beam simplifying sensor alignment during installation. Models are available in through-beam and polarized retroreflective as well as background suppression for applications where shiny metals or bright white backgrounds must be ignored.
