Osram SFH309FA 900nm Phototransistor T1 3mm

The Osram SFH309FA-4 Phototransistor is designed for precise optical sensing in industrial environments. Featuring a narrow 12° viewing angle, it focuses detection on a specific direction, minimising interference from ambient light. The device operates at a 900nm wavelength, making it compatible with infrared LED sources commonly used in control systems.

Its unique construction includes a base area placed axially on the opposite side of the screen, enclosed within a bezel that effectively reduces the influence of side light. This design ensures high linearity, allowing for accurate signal transmission and reliable performance in demanding applications.
