ITR9909
█ Descriptions
The ITR9909 consist of an infrared emitting diode and an NPN silicon phototransistor,
encased side-by-side on converging optical axis in a black thermoplastic housing .
The phototransistor does not receive radiation from IR LED in normal situation, but when an
object comes closer, the radiation is reflected by the object and phototransistor receives the
more radiation as closer the object comes.
For additional component information, please refer to IR and PT.
