7.1 Alignment
Sensor with red light:
Align sensor on object. Select the position so that the red emitted light beam hits the
center of the object. You must ensure that the optical opening (front screen) of the
sensor is completely clear [see
figure 2 ].

7.2 Check the application conditions
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 correspond‐
ing diagram [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/background 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.
