Compact Foreground Suppression Sensors Enable Consistent Detection Regardless Of Target's Color, Reflectivity Or Background
Banner Engineering introduces the World-Beam QS18 Adjustable-Field Foreground Suppression Sensors, designed to reliably detect objects regardless of color, reflectivity, surface irregularities or background conditions. The sensor’s universal mounting design makes installation quick and easy, while a simple screwdriver adjustment allows for precise setup of sensing range. With a compact and IP67-rated sealed housing, the QS18 adjustable-field sensors deliver an exceptional sensing solution for small or difficult-to-reach areas. The QS18 Adjustable-Field Foreground Suppression Sensors operate in diffuse mode, detecting light returned by the background, but ignoring light returned by the object. The concept is similar to that of a polarized retroreflective sensor; if the sensor cannot see the background (reflector), the output switches on—indicating that the target object is present. These compact sensors are available in two adjustable cutoff ranges: 15-40 mm and 30-200 mm. The short-range models are ideal for detecting thinner objects that are closer to the background.
