Sensor Alignment
Position the 45BPD sensor so that the distance from the object to the sensor will be within the sensing range of
the sensor.
The sensor should be mounted at an angle of approximately 5° for very reflective targets as shown in Figure 1.
Figure 1
The sensor should be mounted perpendicular to the direction of travel for targets which have steps, border lines,
and round targets (see Figure 2).
Figure 2
The sensor will provide more precision when the spot size is not larger than the feature that is being measured
(see Figure 3).
