Figure 9-3 Unsafe Mounting Example
Interruption is not detected because of the reflection. Reflective surface interference may also appear above and
below the sensing field.
Figure 9-4 Worst Case Alignment Example
This example shows the minimum distance from the reflective surface, d, to one side of the beam center line.
