ITR9908规格书 ， ITR9908是一款光电开关
The ITR9908 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 receives
radiation from the IRED only. This is the normal situation. But when
an object is in between, phototransistor could not receives the
radiation. For additional component information, please refer to
IR204/L10 and PT204-6B
