Infrared LED

L9337 series

High power LED for optical switches

www.hamamatsu.com

The L9337 series is an infrared LED developed for optical switches. Because a high-power LED chip is mounted, the L9337

series provides higher radiant output power than previous devices, moreover it is available at a low cost due to the improved

manufacturing process. The L9337-01/-02 use a high reliability package making them suitable for automobile applications.
