WTS26x-xxxxxx2xAxx with Teach-Turn adjustment:
The sensing range is adjusted by pressing the teach-in button (approx. 1-3 seconds).
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 object within the sensing range, e.g.
sensing range has been adjusted, the object is removed from the path of the beam,
which causes the background to be suppressed. The digital output changes
