Adjustable-field sensors

Banner Engineering introduces two mid-range adjustable-field sensors to the WORLD-BEAM QS30 family, expanding the 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 a myriad of industrial applications, including part-in-place detection, feeder bowl control and package detection on conveyors. The use of a 128 pixel camera (linear imager) makes the sensors resistant to mechanical shock and vibration, enabling advanced image processing to maximize the range and minimize the effects of target color. The sensors also have high crosstalk immunity and can reject fluorescent or other spurious light signals, allowing multiple sensors to be used in close proximity to one another. 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. The QS30AF/AFF models are available in a waterproof, epoxy encapsulated IP67-rated housing, making them suitable for use in even the harshest of industrial environments. Providing a variety of mounting options, including a 30 mm threaded barrel or side mount, the sensors deliver increased flexibility to meet diverse applications. Three connection options: 2m, 9m quick-disconnect and 150mm pigtail quick-disconnect, are also available. The QS40AFF400 model offers an adjustable cutoff range of 50-400mm, with a maximum sensing range of 400mm for all sensor colors. The QS30AF600 model delivers an adjustable cutoff range of 50-600mm, with a maximum sensing range of 400mm for the 6% black card sensor and 600mm for the 90% white card sensor. The 6% black card sensor also offers a minimum sensing range—also known as the dead zone—of 30mm. Edited by Constanze Schmitz
