Banner Engineering has introduced the World-Beam QS18 adjustable field foreground suppression sensors, designed to detect objects reliably regardless of colour, 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 sealed housing, the QS18 sensors deliver a sensing solution for small or difficult-to-reach areas.
The 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 polarised retro-reflective sensor; if the sensor cannot see the background (reflector), the output switches on – indicating that the target object is present. “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.
Available in two adjustable cut off ranges: 15-40 and 30-200 mm. The short-range models are ideal for detecting thinner objects closer to the background. The QS18 sensors are particularly useful if the following application conditions are present:
* Target object is reflective.
* Reflective background.
* Detecting dark objects on light backgrounds.
* Sensors are aimed toward factory lights.
The following features are advantageous in challenging material handling and packaging applications:
* Adjustable range.
* Reliable detection when a fixed background is present and the object colour or shape varies.
* Objects detected up to the face of the sensor (no dead zone).
* Simple multiturn screw adjustment.
* Crosstalk immunity algorithm allows two sensors to be used in close proximity.
* Visible red emitter for simple sensor alignment.
