Banner Engineering Corp. introduces the World-Beam QS30 Clear Object Sensor, providing reliable clear object detection to solve challenging applications. The Clear Object Sensor utilizes an advanced optical design to allow the sensor to see translucent materials, ensuring dependable detection of clear targets including PET bottles and glass containers. Additionally, the optical design prevents the sensor from being tricked by specular reflections, allowing the sensor to detect optically engineered surfaces such as mirrors, LCD glass with polarizing films, and semiconductor wafers.

The Clear Object Sensor is easily configurable using either the push button on the sensor or via a remote input line. The user can select from one of three switching thresholds—light, medium or dark, depending on the target’s transparency level—to optimize detection and maximize sensing stability. The sensor also features an automatic compensation algorithm, which adapts the switching threshold to the sensor’s environment in real time. Small changes due to dust or contamination on the sensor and reflector or small changes caused by ambient temperature shifts are filtered out by the microcontroller. These features ensure long and trouble-free sensor operation.

The World-Beam QS30 Clear Object Sensor delivers high-accuracy clear object detection in a wide range of applications, including:

  • Bottle jam detection, bottle counting, and bottle down detection
  • Food processing and packaging machines
  • Plate glass or clear web detection
  • Semiconductor wafer detection
These features of the Clear Object Sensor make it particularly useful in the above applications:
  • Reliable detection of clear, translucent, or opaque targets—including reflective surfaces
  • Rugged housing for harsh environments; rated IP67 (NEMA 6), 1200 psi washdown per NEMA PW12
  • Automatic compensation algorithm compensates for dust or contamination on the sensor or reflector and for ambient temperature changes
  • Range of 100 mm to 2 m, with a fast 0.5 millisecond response rate
  • Easy-to-read bar graph display for easy configuration and status monitoring during operation
  • Three selectable thresholds based on type of target being detected
  • Visible red emitter beam for simple alignment
  • Easy configuration via push buttons or remote wire
  • Compact worldwide standard housing, mounting versatility—30 mm threaded barrel or side-mount
  • Bright LED indicators for power and output status
  • 10 to 30V dc operation
