Optic receiver module

[Ta=25?é]

[Ta=25?é, Vcc=5.0V]

*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 50mVP-P under the measuring circuit
