Smartly Com­bi­ned: 2 in 1 – Dis­tan­ce and In­ten­sity De­tec­ti­on

The PNG//smart se­ri­es 1P for­mat reflex light bar­ri­ers are imp­res­si­vely ver­sa­ti­le thanks to their re­li­ab­le de­tec­ti­on met­hod, which com­bi­nes dis­tan­ce and in­ten­sity de­tec­ti­on. By com­bi­ning both prin­cip­les, the sen­sors de­tect ob­jects re­gard­less of color, shape and sur­fa­ce. The reflex light bar­ri­ers de­tect ob­jects up to a dis­tan­ce of 1 m using red LED light. All they need for their func­ti­on is a de­fi­ned backg­ro­und, which re­mo­ves the need for ad­di­ti­onal mo­un­ting of a ref­lec­tor. The dy­na­mic re­ad­just­ment of the switching th­res­hold auto­ma­ti­cally com­pen­sa­tes for gra­du­al con­ta­mi­na­ti­on, which en­su­res a high level of ope­ra­ti­onal re­li­abi­lity.
