Proximity sensors with constant switching distances, irrespective of material, have
the advantage that in the case of changing material no re-adjustment is required,
and a single switching distance is continually maintained, as in the case of standard
proximity sensors with the standard steel plate in steel S 235 JR. Example Inductive proximity sensors with switching distances of 5 mm, 10 mm and 15 mm,
each independent of type of metal. 100
