What are those factors that can influence operating sensing distance (Sa) of inductive sensors?

·         Ambient Temperature ( Kθ ).
·         Material of object to be detected: The fixed sensing distance models for ferrous/non-ferrous (Fe/NFe) materials enable the detection of different objects at a fixed distance, regardless of the type of material. (Km).
·         Size of object to be detected:  When calculating the sensing distance for the selection of a sensor, make the assumption that ( Kd = 1 ).
·         Variation of supply voltage (Kt).
·         Sensor’s nominal sensing distance Sn.
·         Sensing Distance (Sa) for a Sensor with nominal sensing distance (Sn)

                         = Sn x Kθ x Km x Kd x Kt
