5mm Round-Top Infrared Emitter An 850nm/940nm infrared emitter with a GaAs chip and a forward voltage of 1.2~1.6V, used for infrared remote-control transmission, security illumination and through-beam sensing. Supports 38kHz carrier modulation. Supplied directly by Dongguan Hongcheng Optoelectronics Co., Ltd. (an international member of Guangyu Group with over 20 years of LED packaging experience), it features Grade A chips and 99.99% pure gold wire bonding, and is RoHS certified. Free samples and custom wavelength, angle and power binning are available. Download the datasheet PDF on this page for complete electrical specifications and mounting dimensions.
Q: How should I choose between 850nm and 940nm infrared LEDs?
A: Choose 850nm for camera illumination (high sensitivity and long range), or 940nm for covert surveillance and sensing (no visible red glow). Radiant-power binning and pairing are available.
