High Precision Polarized Retro Reflective Sensor PTL-PM12DNR-D with long detection range 12m

Regular retroreflective sensors can detect almost all objects. But they have trouble detecting shiny objects like polished surfaces or mirrors. A standard retro-reflective sensor cannot detect such objects as they can be ‘fooled’ by the shiny object by reflecting the emitted beam back to the sensor. But a polarized retro-reflective sensor can realize normal detection about transparent objects, shiny or highly reflective objects accurately.  i.e., clear glass, PET and transparent films.
