SIR-34ST3F
The SIR-34ST3F is a GaAs infrared light emitting diode housed in clear plastic. This device has a high luminous
efficiency and a 950nm spectrum 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.
