World-Beam QS18 background suppression sensor

The World-Beam QS18 background suppression sensor ignores everything beyond a set distance of up to 300 mm, permitting operation in areas where the background cannot be controlled. Its companion foreground suppression sensor detects objects of any shape or color that come between it and an unchanging background, up to 200 mm away, without a blind zone. These sensors are suitable for use in packaging machinery, solar panel production, material handling, food processing, and pharmaceutical applications. They do not react to fluorescent light, which allows them to be placed below conveyors, facing overhead lighting. A multi-turn screw adjustment allows the user to set the cutoff distance, and the sensors’ built-in crosstalk immunity allows multiple sensors to be used in close proximity. The sensing beam is a visible red light emitting diode (LED), and output options include negative-positive-negative (NPN), positive-negative-positive (PNP) and bipolar (1 NPN, 1 PNP). The sensors have a wide range of mounting and durability options, including IP67 and National Electrical Manufacturers Association (NEMA) 6-rated models that can withstand harsh environments.
