| *1 The above data was obtained using an aluminium target (A5052 t=1 mm). When measuring steel or stainless steel targets, refer to the characteristics of linearity for these materials. *2 NPN output can easily be converted to PNP output by connecting the optional OP-5148 PNP Output Converter. *3 When the distance between the sensor head and the target is 50 % of the measuring range and the operating temperature is 10 to +40 °C (EX-008) or 0 to +50 °C (EX-016 and EX-022). *4 The above data was obtained using an aluminum target (A5052 t = 1 mm). When measuring steel or stainless steel targets, refer to the characteristics of linearity for these materials. |
