Unformatted text preview: switching distance is generally specified by 0.9 sr < su < 1.1 sr,
or partly as above by 0.81 sn < su < 1.21 sn, which is the same. 206 © Festo Didactic GmbH & Co. KG • FP 1110 13. Technical terms relating to proximity sensors Switching hysteresis
The difference between the switch-on point and switch-off point during the axial or
radial approach of the calibrating plate to the active surface of a proximity sensor.
Useful switching distance
The switching distance of an inductive proximity sensor within the full rated supply
voltage and temperature ranges. Maximum deviation from the real switching
distance is ±10 %.
Working switching distance
Switching distance of an inductive proximity sensor within which reliable operation
is guaranteed, independent of manufacturing tolerances or environmental factors.
The values are between 0 and the lowest value of the useful switching distance. 13.3
