Performance
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
standard optical system in Fig. 2.
1. Linear reception distance characteristics
When L=0.2 to 10.5(9.0)^*6m, ^*7EV 10 lx and 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 30in 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 in Fig.2, the output signal shall meet the electrical characteristics in the attached list.
*6 In case of B.P.F. center frequency f0 :56.8kHz model
*7 It refers to detector face illuminance
*8 Outer peripheral light source: CIE standard light source A shall be used and placed at 45from perpendicular axis at the detector face center

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=2.6A at E V =100 lx.
(E_V is an illuminance by CIE standard light source A (tungsten lamp).)
