6.3 Dual Mode Considerations for Clear and TransparentObject DetectionThe Q5X is able to detect the very small changes caused by transparent and clear objects. A transparent object can bedetected 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 darksurfaces. 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 thesensitivity and the output switches when the match percentage to the reference point crosses the switch point. Yourspecific application may require fine tuning of the switch point, but these values are the recommended starting values:Switch point (%) Typical Applications75 (default) Default, recommended for PET bottles and Trays88 Recommended for thin films50 Recommended for tinted brown, tinted green, or water-filled containersCC10° or moreUp to the maximum sensing distanceReference SurfaceSeparate as far as possibleMove as closeas possibleTilt the beamaxis downwardIt can also betilted left or rightFigure 26.
