Used to judge the presence/absence of a workpiece using the pre-determined background

(reference surface) as the reference. Unlike 1-point tuning, this method focuses on the detection

of the absence of workpiece. Insufficient light level or outside-range errors caused by

complicated workpiece appearance are judged as "the presence of the workpiece".

writing life when performing measurement-by-measurement tuning.

Fine Adjustment of Hysteresis Width

2-5

●

Hysteresis Width Setting

A minute step can be judged by adjusting the hysteresis width according to the

workpiece. However, note that the judgment output varies if lowering the hysteresis

width while the displacement value is varying due to moving workpiece or low

reection light intensity.

●

What is Hysteresis Width?

A point in which a judgment output turns from OFF to ON is called an operating

point, and a point in which a judgment output turns from ON to OFF is called a return

point. On this sensor, threshold means operating point, and a distance to the return

point can be set based on the hysteresis width.

Note that the direction where the hysteresis width is set for the threshold differs

depending on ON/OFF of the area output.
