LEDs offer superior reliability with 50,000+ hour lifespan, faster response times (<100 ns vs milliseconds), lower power consumption, better temperature stability, and resistance to vibration/shock in industrial environments.
Infrared (850-950 nm) provides best signal-to-noise ratio and immunity to ambient light interference, while visible red (630-660 nm) allows visual alignment during installation and maintenance.
