Flush Mounting: Fixing of switches in the metal up to their sensing face. Non-Flush Mounting: These switches are to be mounted keeping metal free zone around its sensing face. SENSING DISTANCE Sensing Distance of inductive Proximity Switch depends on, Size of the Proximity Switch/ Sensing Face and Material to be sensed. OBJECT The sensing distance specified here is for object made of mild steel, having thickness of 1 mm. Size of the object should be at least equal to the diameter of switch / sensing face. For object other than M.S. apply suitable correction factor CORRECTION FACTOR : Apply following correction factor (%) when object is other than Mild Steel.
