*1 F.S. (= 30 mm) indicates the range resulting from 2.5 mm subtraction from each end of the 35 mm measuring range.
*2 Typical data obtained when the T-to-R distance was 100 mm, the receiver-to-target distance was 50 mm and a knife edge was used to interrupt the laser beam.
*3 Typical data obtained when the T-to-R distance was 100 mm and the receiver-to-target distance was 50 mm .
*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, the receiver-to-target distance was 50 mm and a knife edge was used to interrupt the
laser beam.
*8 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.
