Sensors: Photoelectric sensor has adjustable field, foreground suppression
Foreground suppression sensors enable detection regardless of target 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. 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
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
