An ML6 model with dual sensor redundant detection and independent outputs provides dual beams from two emitter LEDs that reflect light to two receivers, and two independent outputs indicate the state of each separate beam. This enables users to affordably align or guide translucent paper, plastic and fabric webs because it serves as two sensors in one package. When the web is properly positioned one beam detects the web while the other beam does not. This sensor can also be used to detect a gap between two objects to suppress the detection of small particles such as textile fibers. Other potential applications include semiconductor and PCB positioning for conveying and buffering.
