FEATURES
-
The BL-GD-ITR8102 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 IR LED only. This is the normal situation.
-
When an object is in between, phototransistor could not receives the radiation.
-
For additional component information, please refer to IR908-7C and PT908-7C
