L9437 is an infrared LED developed for optical encoders. By improving the aspherical lens used with the previous type L8506, we have achieved an even more highly collimated beam of near infrared light. The lead pin of L9437 has no step piece that is usually formed at the lead base brazed to the package, thus eliminating the restriction in printed circuit board design.

Features
● Collimated light beam
● Uniform light spot
● Narrow directivity: ±5˚
● High-speed response: 40 MHz Typ.
● High reliability

Applications
● Optical encoder
