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 Q4X 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 190074.
1. Select a reference surface with these characteristics where possible:
• Matte or diffuse surface finish
• Fixed surface with no vibration
