■ Performance
Using the transmitter shown in Fig. 1, the output signal of the light detecting unit is good enough to meet the following items in the
standard optical system in Fig. 2.
1. Linear reception distance characteristics
When L=0.2 to 8.5(7.0)*6m, *7EV＜10 lx and φ=0°in Fig.2, the output signal shall meet the electrical characteristics in the attached list.
2.Sensitivity angle reception distance characteristics
When L=0.2 to 6.0(4.5)*6m, *7EV＜10 lx and φ≦30°in Fig.2, the output signal shall meet the electrical characteristics in the attached list.
3.Anti outer peripheral light reception distance characteristics
When L=0.2 to 4.0(3.0)*6m, *7*8EV≦300 lx and φ=0°in Fig.2, the output signal shall meet the electrical characteristics in the attached list.
*6 In case of B.P.F. center frequency f0 :56.8kHz model
*7 It refers to detector face illuminance
*8 Outer peripheral light source: CIE standard light source A shall be used and placed at 45°from perpendicular axis at the detector face center

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.
(EV is an illuminance by CIE standard light source A (tungsten lamp).)

■ Precautions for Operation
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.)
n
・Total duty ratio Dt (Emitting time t
Σ N / Transmitting time for 1 block T) : 40% or less.
N=1
・ON signal time TON：200μs or more.
Transmitting time for 1 block:T
TON
t1
t2
t3
tn
n
Dt =(Σ tN /T)×100 (%)
N=1
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.
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.
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.
4. The shield case should be grounded on PCB pattern.
(The area across the shield case and the GND terminal is internally non-conductive.)
5. Do not apply unnecessary force to the terminal and the case.
6. Do not push the light detector surface (photodiode) from outside.
7. To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc.
8. Do not use hole and groove set in the case of the light detecting unit for other purposes, since they are required to maintain the
specified performance.
9. External Circuit Examples (Mount the outer parts as near the unit as possible).

(Circuit parameters)
R1=47Ω±5%
C1=47μF
In setting R1 and C1, use suitable values after considering under the real condition
The circuit constant is a example. It is difference from mounting equipment. Please select it by your mounting equipment.
This device has a transistor as protection element between VCC and GND to improve anti-static electricity proof.
Please be carefully not to apply exceeding the absolute maximum ratings of applying voltage and continuous high voltage spike
noise because there is cases that transistor will be short by secondary breakdown generally. In order to do difficultly, Please add CR
filter(47Ω(1/10W), 10μF or more)such as external circuit example above near VCC.

10. 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.
11. 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.
12. 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.
13. This product dose`t correspond to soldering by reflow.
14. Please use this device away from the dew drop.
Be aware that the dew drop rusts shield case and others, may affect the electric characteristics.
