Product Benefits
- Perfect optical coupling
- Fast switching times
- Wavelengths: 850 & 940 nm
- With / without daylight filter
Perfect Match Efficiency
The maximum sensitivity of the photodetectors perfectly matches the emitter spectrum.
Perfect match of IR LEDs and Photodetectors:
100 % @ 940 nm with filter
95 % @ 850 nm without filter
Switching Time up to 100 MHz
The extremely fast switching time of a few nanoseconds ensures high data transfer rates.
