Infrared light emitting diode, top view type
SIR-341ST3F
The SIR-341ST3F is a GaAs infrared light emitting diode housed in clear plastic. This device has a high luminous efficiency and
a 940nm peak wavelength suitable for silicon detectors. It is small and at the same time has a wide radiation angle, marking it
ideal for compact optical control equipment.
