Descriptions
‧The IRM-8881T 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-8881T is the standard IR remote control
receiver series, supporting all major transmission codes.
Applications
1. Optical switch
2. Light detecting portion of remote control
․AV instruments such as Audio, TV, VCR, CD, MD, etc.
․Home appliances such as Air-conditioner, Fan , etc.
․The other equipments with wireless remote control.
․CATV set top boxes
․Multi-media Equipment

Test Method:
The specified electro-optical characteristics is satisfied under the following
Conditions at the controllable distance.
cMeasurement place
A place that is nothing of extreme light reflected in the room.
dExternal 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)
eStandard 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).
