Sensing range setting

Subject to change without notice
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 table
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 [table 12 1] as follows:
Example: x = 200 mm, y = 15 mm. That is, the background (white, 90%) is suppressed
at a distance of > 15 mm of the configured sensing range.

WTL16, WTS16x-xxxxxx2xAxx with Teach-Turn adjustment:
The sensing range is adjusted by pressing the teach-in button (approx. 1-3 sec.).
Depending on the requirements, the potentiometer can be used for fine-tuning (without
pressing the teach-in button).
Clockwise rotation: Sensing range increased.
Counterclockwise rotation: Sensing range reduced.
The sensing range can also be adjusted using just the potentiometer. We recommend
placing the sensing range in the object, e.g.
range has been adjusted, the object is removed from the path of the beam, which
causes the background to be suppressed and the switching output to change
