          *1 F.S. (= 30 mm 1.18") indicates the range resulting from 2.5 mm 0.10" subtraction from each end of the 35 mm 1.38" measuring range.
          *2 Typical data obtained when the T-to-R distance was 100 mm 3.94", the receiver-to-target distance was 50 mm 1.97" and a knife edge was used to
          interrupt the laser beam.
          *3 Typical data obtained when the T-to-R distance was 100 mm 3.94" and the receiver-to-target distance was 50 mm 1.97".
          *4 When the number of averaging measurements is 16
          *5 This is a typical example when the distance between the transmitter and receiver has been set to 100 mm and a knife edge has been used to block light at a position that is 50 mm from the receiver. F.S. = 30 mm displays the measurement accuracy range.
          *6 NPN output can easily be converted into PNP output by connecting the optional OP-5148 PNP output converter.
          *7 Typical data obtained when the T-to-R distance was 100 mm 3.94", the receiver-to-target distance was 50 mm 1.97" and a knife edge was used to interrupt the laser beam.
