Descriptions
‧The
IRM-36xxAF4 SERIES are miniaturized receivers for
infrared remote control systems. PIN diode and preamplifier are
assembled on lead frame, the epoxy package is designed as IR
filter. The demodulated output signal can directly be decoded
by a microprocessor. IRM-36xxAF4 SERIES is the standard IR
remote control receiver series, supporting all major transmission
codes.

Test Method：
The specified electro-optical characteristics is satisfied under the following
Conditions at the controllable distance.
Measurement place
A place that is nothing of extreme light reflected in the room.
External light
Project the light of ordinary white fluorescent lamps which are not high
Frequency lamps and must be less then 10 Lux at the module surface.
(Ee≦10Lux)
Standard transmitter
A transmitter whose output is so adjusted as to
Vo=400mVp-p
and the output
Wave form shown in Fig.-1.According to the measurement method shown in
Fig.-2 the standard transmitter is specified.
However , the infrared photodiode to be used for the transmitter should be
λp=940nm,∆λ=50nm.
Also, photodiode is used of PD438B(Vr=5V).
