■ 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 8m, *5 Ee< 10 lx and φ = 0˚ in Fig. 2, the output signal shall meet the electrical
characteristcs in the attached list.
( 2 ) Sensitivity angle reception distance characteristics
When L= 0.2 to 6m, *5 Ee< 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 4m, *6 Ee<= 300 lx and φ = 0˚ in Fig. 2, the output signal shall meet the electrical
characteristics in the attached list.
*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 the perpendicular axis
at the detector face center.

In the above figure, the transmitter should be set so that the output Vout can be 40mVPP .
However, the PD49PI to be used here should be of the short-circuit current I SC = 2.6µ A at E V =
100 lx.

■ Precautions for Use
( 1 ) Use the light emitting unit ( remote control transmitter ) , in consideration of performance,
characteristics and operating condition of light emitting device and the characteristics of
the light detecting unit.
( 2 ) 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 with soft cloth so as to prevent scratch In case some solvents
.
are required,
use metyl alcohol ethyl, alcohol or isoprophyl alcohol. Also, protect the light detecting unit
against flux and others.
( 3 ) The shield case shall be grounded on PWB pattern.
( 4 ) Do not apply unnecessary force to the terminals and case form outside.
( 5 ) Do not push the light detector surface ( photodiode ) from outside.
( 6 ) To avoid the electorstatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc.
( 7 ) 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 infrared remote control ”
issued form Japan Association of Electrical Home Appliances ( AEHA ) in July 1987.
( 8 ) As for other general cautions, refer to the chapter “ Precautions for Use” ( page 78 to 93 ) .
