Pepperl+Fuchs Subminiature photoelectric sensors
ML6 series subminiature photoelectric sensors come with dual-sensor redundant detection and independent outputs. These models provide dual beams from two emitter LEDs that reflect light to two receivers, while two independent outputs indicate the state of each separate beam. Because these models act as two sensors in one housing, users can align or guide translucent paper, plastic and fabric webs and detect a gap between two objects to suppress the detection of small particles such as textile fibers. The sensors also are available in long-range background suppression sensing models and retroreflective models with no sensing deadband.
