Features

/K6C High radiant output power: 1.5 times higher than previous device (L2656) /K6C High reliability /K6C Low price

Applications

/K6C Optical switches LED High power LED for optical switches L9337 Infrared LED 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.
