Description:
The NTE3104 is a subminiature photo reflector whose GaAs infrared emitting diode and silicon transistor are assembled in the same package allowing for easy installation and handling.
The NTE3104 has an excellent S/N ratio (more than 40dB) and contains a built–in filter for cutting visible light.
Typical applications for the NTE3104 include strobe detection in audio turntables, tape end detection, automatic vending machines, and various other automatic control units.
