ams OSRAM SFH 4049B/BR Chip LED Lens 940nm Infrared Emitters
ams OSRAM SFH 4049B/BR Chip LED Lens 940nm Infrared Emitters are engineered to deliver high optical output in space-constrained sensing and illumination applications. Housed in an ultra-small SMT package with a black epoxy lens, these emitters provide efficient infrared performance for access control systems, factory automation equipment, appliances, tools, and eye/face/hand-tracking technologies. The SFH 4049B features a standard top-emitting configuration. At the same time, the SFH 4049BR offers a reverse-mount design with identical optical performance, giving designers greater flexibility in PCB layouts and system integration.
Designed for reliable, high-speed operation, the ams OSRAM SFH 4049B/BR emitters feature a 940nm centroid wavelength, 950nm peak wavelength, and a narrow 8° half-angle for highly focused infrared illumination. The devices deliver up to 205mW/sr radiant intensity at 70mA and 285mW/sr at 100mA, while fast 12ns rise/fall times enable use in advanced sensing and communication systems. With ESD protection up to 2kV, support for pulsed currents up to 0.7A, and an operating temperature range of -40°C to +85°C, the SFH 4049B/BR emitters combine high optical power, durability, and efficiency for demanding industrial, security, and tracking applications.
