When L=0.2 to 8 m, Ee < 10 lx and
=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 m, Ee < 10 lx and
<= 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 m, Ee <= 300 lx and
=0 in Fig. 2, the output signal shall meet the electrical characteristics in the attached list.

The carrier frequency of the transmitter, however, shall be same as *4, and measurement shall be taken of the 100th and subsequent pulses after start of transmission.
*5 It refers to detector face illuminance.
*6 Outer peripheral light source: CIE standard light source A shall be used and placed at 45 from perpendicular axis at the detector face center.
Transmitter (GL521 used)
In the above figure, the transmitter should be set so that the output V can be 40mV .
However, the
PD49PI
to be used here should be of the short-circuit current I =2.6
A at E =100 lx.
(E is an illuminance by CIE standard light source A (tungsten lamp).)

Precautions for Operation
1) In case of adopting the infrared light detecting unit for the wireless remote control, use it in accordance
with the transmission scheme and the signal format recommended in "Countermeasures for malfunction prevention of
home appliances with remote control" issued from Japan Association of Electrical Home Appliances (AEHA) in July, 1987.
Use of a transmission scheme and a signal format different from those recommended may cause malfunction of home appliances.
(Example : signal format without leader signal, bit structure of small duty ratio (T /(T +T )))
2) Use the light emitting unit (remote control transmitter), in consideration of performance, characteristics,
operating conditions of light 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 PWB pattern.
(The area across the shield case and the GND terminal is internally conductive in some cases and non-conductive in some other cases.)
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.
