FEATURES

  1. 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,
  2. The phototransistor receives radiation from the IR LED only. This is the normal situation.
  3. When an object is in between, phototransistor could not receives the radiation.
  4. For additional component information, please refer to IR908-7C and PT908-7C
