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.
The QS18 Foreground Suppression Sensors are particularly useful if the following application conditions are present:
The following features make the QS18 Foreground Suppression Sensors advantageous in challenging material handling and packaging applications:
“These photoelectric sensors are an ideal solution for material handling or packaging applications where irregularly sized/positioned or shiny objects are present against a fixed background,” said Mike Turner, Material Handling Business Development Manager at Banner Engineering.
