SIR-320ST3F
The SIR-320ST3F is a GaAs infrared light emitting diode housed in clear plastic. This device has a high luminous efficien-
cy and a 940 nm spectrum suitable for silicon detectors. It is small and at the same time has a wide radiation angle,
making it ideal for compact optical control equipment.
