Alignment with background suppression
Align the sensor with the 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 5: Sensor on object
Alignment with foreground suppression
Align the sensor with the background. You must ensure that the optical opening (front
screen) of the sensor is completely clear
Figure 6: Alignment on background
WTM12L are photoelectric proximity sensors with background and foreground suppres‐
sion. Depending on the remission factor of the object to be detected, and perhaps the
background behind it, a minimum distance (y) between the set sensing range (x) and
the background is to be maintained.
WTM12L-xxxxx8xxxxx:
Check the application conditions:
Background suppression: MultiMode 1, 3, 4, 5, 6
Adjust the sensing range and distance to the object and background as well as the
remission capability of the object according to the corresponding diagram (x = sensing
range, y = minimum distance between set sensing range and background (white, 90%))
figure 5].
[see figure 6].
