Dual Mode Reference Surface Considerations

Optimize reliable detection by applying these principals 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. For
detailed instructions for detecting clear or transparent objects, refer to the Instruction Manual, p/n 208794.
1. Select a reference surface with these characteristics where possible:
• Matte or diffuse surface finish
• Fixed surface with no vibration
• Dry surface with no build-up of oil, water, or dust
2. Position the reference surface between 200 mm (20 cm) and the maximum sensing range.
3. Position the target to be detected as close to the sensor as possible, and as far away from the reference surface as
possible.
4. Angle the sensing beam relative to the target and relative to the reference surface 10 degrees or more.
