Sensing object
Ferrous metals approximately the same size as the proximity sensing face for shielded models and twice the size of
the sensing face for unshielded models. The specified sensing distances above are based upon tests with mild steel
standard targets. Other materials will reduce the sensing range (Sn) as follows: Stainless Steel Sn x 0.85, Brass Sn x
0.5, Copper Sn x 0.46 Aluminum Sn x 0.40
