*1. It specifies the maxmum distance between emitter and detector that the output wave form satisfies the standard under the conditions
below against the standard transmitter.
1) Measuring place
: Indoor without extreme reflection of light
2) Ambient light source
: Detecting surface illumination shall be irradiate 200±50lx under ordinary white fluorescence lamp without
high frequency lightning
3) Standard transmitter
: Burst wave of standard transmitter shall be arranged to 400mVP-P under the measuring circuit

1) Transmitter(IRED) drive current
: IFP = 300mAP-P ~ 600mAP-P
2) R-C Decoupling Filter with Lower Cut-off Frequency
: R=100Ω~470Ω , C=47uF ~ 100uF
⇒ fc = 1/2πRC = 33.9~3.4Hz
3) optional
: External pull-up resistor =10kΩ over , But recommand null
: Cp2 recommand null
