The light output of the LED transmission unit is adjusted so that the transmission output (V out) of the standard
reception unit will be 55 mV when the transmission waveform (duty = 50%) is output from the LED transmission unit. Here, infrared sensitivity (SIR) of PNZ323B is 0.53 µA when emission illuminance (H) is 12.45 µW/
cm2.
The maximum reception distance under these specifications is an assurance that TWH and TWL values will be
within the tolerance ranges when 16 consecutive pulses of an optical output equivalent to the maximum reception distance are transmitted by the above transmission unit (The maximum reception distance is measured in
the dark without external disturbance noise.)
