2-2-4 Mounting Orientation
Mounting Near Walls
Errors will occur if light reflected off a wall surface is received by the Sensor.
If it is not possible to mount the Sensor away from the wall, mount in the way
shown below, i.e., so that the plane containing the emission axis and the
reception axis is parallel to the wall surface.
Also, applying matt black coating to the wall surface will help to reduce the
amount of light reflected.
Narrow Grooves or Indentations
If measurement is performed in an indentation between two walls, or in a
groove, mount the Sensor in the way shown below, i.e., so that the path along
the emission and reception axes is not interrupted by a wall.
