Sensors: Photoelectric sensor has adjustable field, foreground suppression

Foreground suppression sensors enable detection regardless of target color, reflectivity or background.

Banner QS18 foreground suppression sensor
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. Universal mounting design makes installation quick and easy, while a simple screwdriver adjustment allows for precise setup of sensing range.

These photoelectric sensors are a 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 .

With a compact and IP67-rated sealed housing, the QS18 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.

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, said Turner. QS18 foreground suppression sensors are particularly useful if the following application conditions are present:

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
