Infrared light (850-950 nm) provides higher efficiency in photodetector response, better isolation from ambient visible light interference, and allows compact design with minimal light leakage in industrial environments.
The LED's rise/fall time (typically 10-100 ns) directly determines optocoupler switching speed. Faster LEDs enable high-speed data transmission (up to 10 Mbps) in industrial communication interfaces.
