Fixed field sensor with background suppression

November 2011 Sensors & Transducers

Banner Engineering has introduced the World-Beam Q20FF fixed field background suppression sensor to its line of compact photoelectric sensors. The Q20FF has the same high performance as other Banner sensors, but has been enhanced with visible red, fixed field background suppression and a sensing range up to 150 mm. This has increased the range of applications in industries such as materials handling, robot assembly, food and beverage and pharmaceutical goods.

The small emitter beam and well focused optics provide an increased sensing range up to 150 mm and greater immunity to objects beyond the fixed detection range. With electronic immunity to fluorescent light sources, the Q20 fixed field sensors offer more reliable and stable detection in all applications.

The Q20FF provides excellent optical performance in a standard rectangular sensor housing with 25,4 mm mounting hole spacing. Models are available with 50, 100, or 150 mm sensing ranges. It is IP67/NEMA 6 and NEMA PW12 1200 PSI washdown rated and has metallic M8 and M12 connectors on quick disconnect models with a threaded connection to the cord set. It features DC operation from 10 to 30 V DC with complementary solid state outputs (one normally open, one normally closed); sourcing (PNP); or sinking (NPN) by model. A range of mounting brackets and apertures is available.
