Descriptions
The IRM-26xx 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-26xx SERIES is the standard IR
remote control receiver series, supporting all major transmission
codes.

IRM-26xx SERIES
The Notice of Application:
Transmission o remote control signal consist of four parts: Encode Part, IR Transmitter Source,
IRM device, Decode Part
1. When IRM-26xx code select frequency, it need to well understand the center system of
encode part.
2. Strong or weak light of IR Transmitter can affect distance of transmission.
3. Minimum Burst Length Tburst (number of pulses per burst) : 10 cycles
4. It needs to ensure the translation range of decode part if it is applied to the pulse-width range.
If the above items hardly assure of its application, it’ll cause NG(no good) message from the edge
of signal.
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).
Measuring system
According to the measuring system shown in Fig.-3
