Banner Engineering Corp.: Clear object sensor
The World-Beam® QS30 Clear Object Sensor from Banner Engineering uses an advanced optical design to allow the sensor to see translucent materials, including PET bottles and glass containers.
The optical design prevents the sensor from being tricked by specular reflections, allowing it to detect optically engineered surfaces such as mirrors, LCD glass with polarizing films, and semiconductor wafers. Easily configurable using either the push button on the sensor or via a remote input line, three switching thresholds—light, medium or dark, depending on the target's transparency level—can be selected to optimize detection and maximize sensing stability. Small changes in environment are filtered out by the microcontroller.
