          *1 The above data was obtained using an iron target (S45C, SS400, t=1 mm). When measuring aluminium, copper, or stainless steel targets, refer to the linear characteristics for these materials.
          *2 When the digital filter function is used, the sampling rate is 20000 sampling/sec.
          *3 NPN output can easily be converted to PNP output by connecting the optional OP-5148 PNP output converter.
          *4 When the distance between the sensor head and the target is within 50% of the measuring range.
