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
