LITEON LTE-R3838 Infrared Emitters
LITEON LTE-R3838 Infrared Emitters are compact, high-efficiency IR components designed for a wide range of signal transmission applications. Operating typically at a wavelength of 940nm, these emitters are optimized for compatibility with standard infrared receivers. A small footprint and high radiant intensity make these emitters ideal for use in remote control systems, IR data communication, security/surveillance equipment, and industrial automation. The LITEON LTE-R3838 series supports fast switching speeds and narrow viewing angles, enhancing precision in object detection, gesture recognition, and touchless interface systems. These features, combined with low power consumption and high reliability, make the LTE-R3838 devices well-suited for integration into consumer electronics, smart home devices, and medical monitoring equipment.Features
