(1) noise width is measured in a waveform after the four times average with an oscilloscope. (2) ripple noise in the power supply voltage (vcc): 10 mvp-p max. (3) distance from mounting reference plane to target: 6.5 mm (4) resolution is measured by the voltage of response delay time (t r2 ). *4. this is the peak-to-peak value of the deviation of the signal output from a straight line. a linearity of 2% f.s. indicates the following value: (1) distance full-scale converted value: 2 mm 0.02 = 0.04 mm (40 ? m) (2) output voltage converted value: 1.4 mv/ ? m 40 ? m = 56 mv (for a sensor with a sensitivity of 1.4 mv/ ? m) exterior specification electrical and optical characteristics (ta = -10c to 65c) *1. load impedance (between out-gnd) is set at more than 10 k ? . *2. t r1 : rise time of output voltage from 10% to 90%. *3. t r2 : setup time from pls rising edge to measured output value rising edge. be sure to read safety precautions on page 3. appearance sensing method connecting method sensing distance output type model triangulation connector 6.5 1 mm analog output ; % $ 15 35.5 16 item symbol rated value unit remarks supply voltage v cc 7 v --- led pulse light emission control signal pls 7 v led led light emission pulse t fp 100 ms please refer pulsed forward current rated curve operating temperature t opr -10 to +65 c no freezing or condensation storage temperature t stg -25 to +80 c --- item value operating area * 1 6.5 1 mm sensitivity variation * 2 -1.4 mv/ ? m 10% max. resolution * 3 10 ? m max. linearity * 4 2% f.s.
