Universal Retro-Reflex Sensors

Uni­ver­sal retro-​reflex sen­sors are sui­ta­ble for the de­tec­tion of glossy, chrome-​plated or re­flec­ti­ve sur­fa­ces thanks to the po­la­ri­za­tion fil­ter. They work with red light or laser light. Ob­jects are de­tec­ted by in­te­rrup­ting the light beam bet­ween the sen­sor and the re­flec­tor.
