The transmitter and receiver in these sensors are located in a single housing. The sensor evaluates transmitted light reflected back from the object. The output is switched as soon as an object passes the selected range. Bright objects reflect more light than dark objects, and can thus be recognized from greater distances.

Technology that moves in over three decades of wenglor sensoric. On this interactive journey through time, we researched deep into wenglor’s archives and have tracked the history of the company since the eighties – starting in an attic and growing into a global corporation.
Disinfection stations for hands are provided in public areas such as shops, schools, train stations, airports, football stadiums, gyms and many more to meet hygiene standards. The automated disinfectant dispensers have one inlet for each hand. Compact reflex sensors are installed in narrow areas for contactless detection of the hands. The disinfection cycle starts as soon as the sensor has detected that both hands are present. This hygiene measure can combat the spread of germs quickly, effectively and fully automatically.
