SENSORS: Pepperl+Fuchs introduced RLG28 Retro-Reflective Area Sensors. RLG28 retro-reflective area sensors feature six light beams that generate a constant 60 mm detection field to consistently detect objects as small as 12mm in diameter over the entire 0-4m sensing range. They are a perfect sensing solution in material handling and other applications where single beam retro-reflective sensors have reached their functional limitations, or in applications that would otherwise require costly light grids. RLG28 sensors are cULus listed.
With some retro-reflective sensors, shiny objects such as foils, Mylar and certain plastics can be erroneously “seen” as the sensor’s reflector. RLG28 sensors, however, have a polarizing filter that eliminates the potential for such false readings. These retro-reflective area sensors automatically adjust excess gain based on ambient conditions such as lens contamination or temperature changes, enabling constant operation without requiring readjustment. They also offer enhanced status LED indication, better shock and vibration immunity per the international standard EN 60947-5-2, and better low-end temperature rating (to -30C) for freezer/cooler environments.
RLG28 sensors also feature a standard photoelectric sensor housing that is mechanically and electrically compatible with today’s most commonly available photoelectric sensors. As a result, they facilitate fast and easy replacement of single-beam photoelectric sensors.
