NTE3104
Opto Interrupter Module
Photo Reflector, NPN Transistor Output
Description:
The NTE3104 is a subminiature photo reflector whose GaAs infrared emitting diode and silicon tran-
sistor 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鈥搃n 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.
