Two mid-range adjustable-field sensors have been added to the company’s WORLD-BEAM® QS30 family, expanding the company''s line of short and long-range adjustable-field sensors. The QS30AFF400 foreground suppression sensor and the QS30AF600 background suppression sensor use advanced linear imager technology to provide a superior sensing solution for myriad industrial applications, including part-in-place detection, feeder bowl control and package detection on conveyors. The QS30AFF400 sensor offers foreground suppression to deliver reliable detection of target objects varying in color or shape when a fixed background is present. Conversely, the QS30AF600 sensor provides reliable detection of objects when the background condition is neither controlled nor fixed, and it ignores objects located beyond the sensing field cutoff. The sensing range for all models can be adjusted with a screwdriver potentiometer or via the remote teach wire input. Additionally, the sensors’ visible red LED sensing beam ensures easy sensor alignment.
