1 Alignment
Sensor with red light:
Align sensor on object. Select the position so that the red emitted light beam hits the cen‐
ter of the object. You must ensure that the optical opening (front screen) of the sensor is
completely clear [see figure
Figure 2: Alignment
2 Sensing range
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 corresponding dia‐
gram [see figure 3] (x = sensing range, y = transition range between the set sensing range
and suppression of the background as a % of the sensing range (object remission/back‐
ground remission)). Remission: 6% = black 1, 18% = gray 2, 90% = white 3 (referring to
standard white as per DIN 5033). We recommend making the adjustments using an object
with a low remission.
The minimum distance (= y) for background suppression can be determined from diagram
[ figure 3 1] as follows:
Example: x = 100 mm, y = 10 => 10% of 100 mm = 10 mm. That is, the background is
suppressed at a distance of > mm from the sensor.
