ADDITIONAL INFORMATION
6.3. Dual Mode Considerations for Clear and Transparent
Object Detection
The Q5X is able to detect the very small changes caused by transparent and clear objects. A transparent object can be detected either by a
change in intensity, distance, or by a double-peak reflection.
The Q5X sensor can be taught non-ideal reference surfaces, such as surfaces outside of the sensor range or very dark surfaces. Teaching
non-ideal reference surfaces may enable applications other than transparent or clear object detection, but best results for transparent or clear
object detection require a stable reference surface.
The display shows the match percentage to the taught reference point. The user adjustable switch point defines the sensitivity and the output
switches when the match percentage to the reference point crosses the switch point. Your specific application may require fine tuning of the
switch point, but these values are the recommended starting values:
Table 1:Match percentage to taught reference point
Switch point (%) Typical Applications
50 (default) Default, recommended for PET bottles and Trays
88 Recommended for thin films
50 Recommended for tinted brown, tinted green, or water-filled containers
