Switching Output
The switching behavior (NPN, PNP, push-pull, push-pull negated) of the switching output depends on the programming.
With the digital switching output, objects to be measured can be monitored for thresholds being exceeded. A measure-
ment window must be parameterized for this. The parameters for the upper and lower switching threshold and for the
switching hysteresis can be freely selected,

The switching output is activated when there is no target, when the target is too close/far or when no valid measurement
value can be determined.
