Dual Mode Reference Surface Considerations

Optimize reliable detection by applying these principles when selecting your reference surface, positioning your sensor
relative to the reference surface, and presenting your target.
The robust detection capabilities of the Q5X allows successful detection even under non-ideal conditions in many cases.
Typical reference surfaces are metal machine frames, conveyor side rails, or mounted plastic targets. Contact Banner
Engineering if you require assistance setting up a stable reference surface in your application.
Select a reference surface with these characteristics where possible:
1.
◦
◦
◦
Position the reference surface between 200 mm (20 cm) and the maximum sensing range.
2.
3. Position the target to be detected as close to the sensor as possible, and as far away from the reference surface as
possible.
Angle the sensing beam relative to the target and relative to the reference surface 10 degrees or more.

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:
Match percentage to taught reference point
Switch point (%)
50 (default)
88
50
46
Matte or diffuse surface finish
Fixed surface with no vibration
Dry surface with no build-up of oil, water, or dust
Default, recommended for PET bottles and Trays
Recommended for thin films
Recommended for tinted brown, tinted green, or water-filled containers
