Mutual interference

(Unit: mm in)

  • When installing two or more sensor heads side by side, mutual interference will not occur if the laser spots from other sensor heads do not fall within the shaded areas in the figure below. When connecting two sensor heads to one controller, the mutual interference prevention function can be used. Therefore the measures shown below are not necessary in that case.

Sensor head mounting direction

  • To obtain the greatest precision, the sensor head should be oriented facing the direction of movement of the object’s surface, as shown in the figure below.
