How should a retroreflective sensor target be oriented relative to the beam?

Explanation:
Retroreflective sensors rely on light bouncing back into the sensor’s receiver. If the target faces the beam squarely (perpendicular to the beam), the light reflects straight back along the same path and the sensor gets the strongest, most reliable signal. Tilting the target—even slightly—causes the reflected light to go off-axis, so much of it is not captured by the receiver and the detect signal weakens or is lost. So, aligning the target perpendicular to the beam ensures the best possible reflection and reliable sensing.
