HuiYuan 3004K3T-CA is an infrared diode designed for efficient emission of infrared light at a wavelength of 940 nm, with a viewing angle of 30 degrees, housed in a compact 3 mm radial lead package. This IR emitter's specifications make it suitable for applications in remote control systems, proximity sensors, and security systems where precise infrared emission and narrow beam width are required. The device is part of the broader category of IR thermal sensors and operates at a wavelength well beyond the visible spectrum, offering reliable performance in environments where ambient lighting conditions may interfere with other types of detectors. Crafted for durability and precision, it supports engineers in developing advanced optical systems that require consistent and stable infrared output.
