High power LED for optical switches
L9337 is an infrared LED developed for optical switches. Because a high-power LED chip is mounted, L9337 provides higher radiant output
power than previous devices, yet is available at a low cost due to the improved manufacturing process. L9337 also achieves a directivity that
matches applications using a light-transmitting lens.
