█Descriptions
The
ITR8402-F-A
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 IR908-7C-F and PT908-7C-F
