4 / 6 page 4 Sheet No.: OP06008 Fig.2 Standard Optical System Transmitter Reception distance:L Light detector face illuminance:EV VOUT Fig.1 Transmitter 20cm 10kΩ 5V VOUT Oscilloscope Transmitter (GL521 used) f0 (*5) Duty 50% (EV is an illuminance by CIE standard light source A (tungsten lamp).) Using the transmitter shown in Fig. 1, the output signal of the light detecting unit is good enough to meet the following items in the ■ Performance standard optical system in Fig. 2. 1. Linear reception distance characteristics *6 In case of B.P.F. center frequency f0 :56.8kHz model When L=0.2 to 10.5(9.0)*6m, *7EV<10 lx and φ=0°in Fig.2, the output signal shall meet the electrical characteristics in the attached list. 2.Sensitivity angle reception distance characteristics When L=0.2 to 7.5(6.0)*6m, *7EV<10 lx and φ≦30°in Fig.2, the output signal shall meet the electrical characteristics in the attached list. 3.Anti outer peripheral light reception distance characteristics When L=0.2 to 5.0(4.0)*6m, *7*8EV≦300 lx and φ=0°in Fig.2, the output signal shall meet the electrical characteristics in the attached list. *7 It refers to detector face illuminance In the above figure, the transmitter should be set so that the output VOUT (P-P) can be 40mV. However, the PD49PI to be used here should be of the short-circuit current ISC=2.6μA at EV =100 lx. ( φindicates horizontal and vertical directions.) GP1UM26XK0VF/GP1UM27XK0VF Series GP1UM28XK0VF/GP1UM28YK0VF Series *8 Outer peripheral light source: CIE standard light source A shall be used and placed at 45°from perpendicular axis at the detector face center |
