Si1102
For applications where R1 resistance values are small, the proximity range can vary as a function of the ambient IR
condition. A product cover, which limits the visible light intensity, is helpful in reducing this range variation. It is
recommended that the Si1102 be evaluated and tested in-product under the various light conditions it will
encounter under normal product usage. Setting the potentiometer R1 = 0 is not recommended unless the ambient
light condition is known and relatively constant.
At any given R1 threshold setting, there are many factors that determine the precise distance that the Si1102
reports. These factors include object reflectivity, object size, ambient light type and ambient light intensity. When
used in applications where the ambient light is variable, it is recommended the Si1102 optical window be IR
transmissive but visible light opaque.
