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 Terms of electrical characteristic values Nominal voltage Vn A value within the operating voltage rang...
