Sensing Distance Correction Factors
In practice, most targets are generally made of steel and are of a size, equal to or
greater than the sensing face of the sensor. Where this is the case, use the sensing
distance values given in the characteristics for the particular sensor. To calculate the precise
sensing distance for specific applications, the following parameters, which affect the sensing
distance, must be taken into account.
