Sensor with potentiometer:
The sensing range is adjusted with the potentiometer (type: 270°). Clockwise rotation:
sensing range increased; counterclockwise rotation: sensing range reduced. We recom‐
mend placing the switching range in the object, e.g., see Graphic F. Once the sensing
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 (see
Graphic C).
The sensor is adjusted and ready for operation. Refer to Graphics C and G to check the
function. If the switching output fails to behave in accordance with Graphic C, check the
application conditions. See section Error analysis.
