WTB16x-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
