WTB16P: Align the sensor with the object. Select the position so that the red emitted
light beam hits the center of the object. It is important to ensure that the optical
opening (front screen) of the sensor is completely clear
WTB16I: Align the sensor with the object. Select the position so that the infrared light
(not visible) hits the center of the object. The correct alignment can only be detected via
the LED indicators. see figure
that the optical opening (front screen) of the sensor is completely clear.

WTB16 are photoelectric proximity sensors with background suppression. Depending
on the remission 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.
Check the application conditions: Adjust the sensing range and distance to the object
or background as well as the remission capability of the object according to the corre‐
sponding diagram [see figures 5 and 7] (x = sensing range, y = minimum distance
between set sensing range and background (white, 90%)) Remission: 6% = black 1,
18% = gray 2, 90% = white 3 (referring to standard white as per DIN 5033). We
recommend that the adjustment be performed with an object of low remission.
The minimum distance (= y) for the background suppression can be determined from
the diagram [figure 3 1] as follows:
Example: x = 400 mm, y = 25 mm. That is, the background (white, 90%) is suppressed
at a distance of > 25 mm of the configured sensing range.
