Energetic Reflex Sensors

Re­flex sen­sors check ob­jects for pre­sence, check stack heights or per­form coun­ting tasks. They are used when ob­jects need to be de­tec­ted wit­hout a de­fi­ned back­ground. For this pur­po­se, they use red light or in­fra­red light ac­cor­ding to the en­er­gy prin­ciple.
