Photoelectronic Sensors in R Design

The R de­si­gn in­cludes pho­toe­lec­tro­nic sen­sors such as retro-​reflex sen­sors and re­flex sen­sors. The P1R sen­sors are par­ti­cu­lar­ly easy to in­te­grate due to their com­pact for­mat, low ins­tal­la­tion depth and the pos­si­bi­li­ty of moun­ting with an M18 thread. They are used in va­rious ap­pli­ca­tions, for example in ven­ding ma­chine construc­tion.

P1RH Re­flex Sen­sor with Back­ground Sup­pres­sion

  • Ac­cu­rate ob­ject de­tec­tion against any back­ground

  • In­sen­si­tive to shape, color and sur­face fi­nish

  • Easy hand­ling thanks to vi­sible red light


P1RL Uni­ver­sal Retro-​Reflex Sen­sor

  • No mi­ni­mum dis­tance bet­ween sen­sor and re­flec­tor re­qui­red due to single-​lens op­tics

  • Large range and sa­fe­ty thanks to laser class 1 for ver­sa­tile ap­pli­ca­tions


 
Retro-reflex sensor checks the presence of glass bottles

P1RK Retro-​Reflex Sen­sors for Trans­pa­rent Ob­jects

  • Dy­na­mic read­just­ment of the swit­ching thre­shold for re­liable ob­ject de­tec­tion, even for trans­pa­rent ob­jects

  • No mi­ni­mum dis­tance bet­ween sen­sor and re­flec­tor re­qui­red

  • Vi­sible red light and easy in­te­gra­tion with single-​lens op­tics

Ap­pli­ca­tion Va­rie­ty

Fill-​Level Mo­ni­to­ring of Pa­cka­ged Food Pro­ducts in Contai­ners with Retro-​Reflex Sen­sors for Trans­pa­rent Ob­jects

In the food in­dus­try, goods that do not meet qua­li­ty stan­dards are sor­ted into che­ck­wei­ghers and pla­ced in contai­ners after the wei­ghing pro­cess. In order to check their fill level, a retro-​reflex sen­sor for trans­pa­rent ob­jects is ins­tal­led. 

Hand De­tec­tion on Taps with Re­flex Sen­sors with Back­ground Sup­pres­sion

Au­to­ma­tic hand wash ba­sins, soap dis­pen­sers and hand dryers are used in the food in­dus­try, but also in high­ly fre­quen­ted pu­blic areas. A re­flex sen­sor with back­ground sup­pres­sion is moun­ted under the res­pec­tive mixer tap, which trig­gers the water jet, soap dis­pen­ser and hand dryer when hands are de­tec­ted.

Other Usage Options

Transparent Objects
Medical ampoules in a pharmaceutical factory

Reverse Vending Machines (RVM)
In ad­di­tion to the op­ti­cal ope­ra­ting prin­ciples, ul­tra­so­nic sen­sors in R de­si­gn are also avai­lable. By using sound waves, they pro­vide a re­liable so­lu­tion for de­man­ding ap­pli­ca­tions where pre­cise de­tec­tion is es­sen­tial. Thanks to their com­pact de­si­gn and flexible moun­ting op­tions, they are as easy to in­te­grate as their op­ti­cal coun­ter­parts.
