GP1U10X

Compact, Surface Mount and Reflow Soldering Type IR Detecting Unit for Remote Control

Sharp Electronics 

GP1U10X Series

s 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 m, Ee*5 < 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 m, Ee*5 < 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 m, Ee*6 <= 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 perpendicular axis at the detector face center.

Fig. 1 Transmitter

In the above figure, the transmitter should be set so that the output Vout can be 52mVP - P.

However, the PD49PI to be used here should be of the short-circuit current ISC =2.6µ A at EV =100 lx.

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