Clear Container Detection

Plastic container detection is challenging because containers are clear and can have ridges, which may attenuate light differently and can be difficult to detect accurately.

In order to count these containers as they move down the conveyor, it is important to have a dynamic sensor that can sense clear or transparent items and do so quickly and accurately.

YOUR BENEFITS

  • Simple and reliable solution to a difficult problem.
  • Sensor designed specifically for this problem where standard sensors will fail.

  • Clear Container Detection

Banner Engineering's QS30ELVC retroreflective sensor is the ideal solution for detection of clear targets because it has an 8% threshold for unambiguous object detection, which allows a transparent object to be detected as long as it attenuates at least 8% of the light passing through it. The sensor has a minimum range of 100 mm, which is excellent for small conveyors and limited spaces, with a maximum range of 2 m.

The configuration and setup of Banner’s QS30ELVC are quick and easy with a TEACH mode that learns the amount of light reflected back as the clear condition with just a simple touch of a button. The sensor has an automatic compensation algorithm that compensates for dust and contamination on the sensor/reflector for consistent and reliable detection that reduces downtime. The QS30ELVC also compensates for ambient temperature changes.

The QS30ELVC has a 500 microsecond response time to detect clear containers in high speed counting applications accurately, and the reflector is available in a square or smaller rectangular shape to meet various user needs.
