In the above figure, the transmitter should be set so that the output VOUT (P-P) can be 40mV.
However, the PD49PI to be used here should be of the short-circuit current ISC=2.6μA at EV =100 lx.

The circuit constant is a example. It is difference from mounting equipment. Please select it by your mounting equipment.
Please be carefully not to apply exceeding the absolute maximum ratings of applying voltage and continuous high voltage spike
3. Pay attention to a malfunction of the light detecting unit when the surface is stained with dust and refuse.
Care must be taken not to touch the light detector surface.
4. Unnecessary force shoud not be applied to terminal.
5. Do not push the light detector surface (photodiode) from outside.
■Precautions for Operation

Transmitting time for 1 block:T
1. When this infrared remote control detecting unit shall be adopted for wireless remote control, please use the following signal format .
(NEC code,RC-6code etc.)
・Total duty ratio Dt (Emitting time tN / Transmitting time for 1 block T) : 40% or less.
Σ
n
N=1
・ON signal time TON：200μs or more.
In case the signal format of total duty and/or ON/OFF signal time dosen`t meet the conditions noted above, there is a
case that reception distance much reduces or output dose not appear.

2. Use the light emitting unit (remote control transmitter), in consideration of performance, characteristics, operating conditions of
light emitting device and the characteristics of the light detecting unit.
If it should be dirty, wipe off such dust and refuse with soft cloth so as to prevent scratch. In case some solvents are required, use
methyl alcohol, ethyl alcohol or isopropyl alcohol only.
Also, protect the light detecting unit against flux and others, since their deposition on the unit inside causes reduction of the
function, fading of markings such as the part number.
6. To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc.
7. Since conductive thermo plasticity is used in 2nd mold regin,please be careful not to come in contact with PCB land
pattern.

9. There is a possibility that noise on output may be caused by environmental condition (Disturbing light noise, Electromagnetic
noise, Power supply line noise, etc.) even if there is no input transmission signal.
10. Please shall confirm operation or your actual machine. Because the output pulse width of this product is fluctuated by
environmental conditions such as signal format, temperature, distance from transmitter, and so on.
11. In case that this product is kept in high humidity condition, it may be hard to solder, please be careful enough about storage
method.
Depend on the flux you select, there are different solderabilities, so please select a suitable flux and use it.
12. This product dose`t correspond to soldering by reflow.
13. Please make sure in case pf hand soldering that yue the solder iron with less than 45W power and solder iron point(edge)
temperature is less than 320℃ within 3 seconds,and also don't add any force to lead frame directly.And please make sure never
to touch 2nd mold resin by a solding.

14. When using this device,please be careful not to cause dew drop.
Be aware that the dew drop rusts lead pins portion and others, may affect the electric characteristics.
15. The lead flame may be deformed since the device is packed in vinyl bag.
