Subject to change without notice
Align the sensor with the object. Select positioning so that the red transmitted light
beam hits the center of the object. Make sure that the optical opening (front screen) of
the sensor is completely free
an object of low remission.

Figure 4: Alignment
Check the application conditions: Adjust the sensing range and distance to the object
or background and the remission capability of the object according to the correspond‐
ing diagram [figure 5] (x = sensing range, y = minimum distance between the object
and background in mm (object remission/background remission) (remission: 6% =
black, 90% = white) (based on standard white DIN 5033)).
The minimum distance (= y) for background suppression can be read from the diagram
[cf. figure 5 1] as follows:
Example: x = 1,000 mm, y = 25 mm. That is, the background is suppressed at a
distance of > 25 mm behind the object.
