RGB color sensor

S9702

S9702 is a color sensor molded into a plastic package having a 3-channel (RGB) photodiode sensitive to the blue (

λp=460 nm), green

(

λp=540 nm) and red (λp=620 nm) regions of the spectrum. S9702 has a 3-segment (RGB) active area of o1 mm. When compared to the

previous model (S9032-02), S9702 is significantly miniaturized (package size 55 % less in cubic volume, PC board mount space 43 % less

in area).
