The difference between the “operate” and “release” points is called
hysteresis or differential travel (See shaded area in drawing).
It is factory set at less than 15% of the effective operating
distance. Differential travel is needed to keep proximity sensors
from “chattering” when subjected to shock and vibration, slow moving
targets, or minor disturbances such as electrical noise and
temperature drift. Inductive sensors can be actuated in an axial or lateral
