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 181483.
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 50 mm and the maximum sensing range for threaded barrel models or between 60
mm and the maximum sensing range for flush mount models.
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.
