Banner Engineering Corp. introduces two mid-range adjustable field sensors to the WORLD BEAM® QS30 family — a foreground suppression and a background suppression model. The QS30AFF400 (foreground suppression) and the QS30AF600 (background suppression) have been designed to expand Banner's growing line of short and long-range adjustable field sensors. The sensors use advanced linear imager technology to provide a sensing solution for industrial applications such as part-in-place detection, feeder bowl control, and package detection on conveyors.

"Our goal in developing the new QS30AF/AFF models is to provide a high performance, adjustable field sensor capable of twice the detection range with less color sensitivity than Banner's previous generation of sensors," said Dennis Smith, Technical Marketing Manager at Banner Engineering. "The use of a 128 pixel camera (linear imager) makes the QS30 resistant to mechanical shock and vibration, and it enables advanced image processing to maximize the range and minimize the effects of target color. The sensor also has excellent cross talk immunity and can reject fluorescent or other spurious light signals so that multiple Banner sensors can be used in close proximity to one another."

The QS30AFF400 offers foreground suppression for reliable detection when a fixed background is present, though the object color or shape may vary. Conversely, the QS30AF600 provides reliable detection of objects when the background condition is not controlled or fixed, thus ignoring objects beyond the sensing field cutoff. The sensing range for all models is adjusted with a screwdriver potentiometer or via the remote teaches wire input and alignment of the sensor is easy thanks to a visible red LED sensing beam. Both sensors are available in three different waterproof, epoxy encapsulated IP67-rated housings allowing them to be used in even the toughest of industrial environments, while a 30 mm threaded barrel or side mount provides a variety of mounting options.
 

Additional features of the QS30AF/AFF:
* Precise and repeatable switch point performance
* Enhanced immunity to fluorescent lights and cross talk of nearby sensors
* Large, bright output and sensor status indicators
* Four turn potentiometer or remote input teach for setting the switch point distance
* Full assortment of convenient brackets and cordsets are available
* Models are available with cable or integral metal quick-disconnect or M12 pigtail connectors.
* Bipolar discrete outputs, PNP and NPN, with optional LO/DO selection in every model
