5mm Round-Head Infrared Receiver An infrared receiving device used with a 940nm infrared emitter for remote-control reception and photoelectric sensing. 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 customization of carrier frequency, package and leads are available. Download the datasheet PDF on this page for complete electrical specifications and mounting dimensions.
Q: Should I choose an 850nm or 940nm detector?
A: Pair the receiver and emitter by peak wavelength. 940nm is the mainstream choice for remote controls and sensing (strong rejection of visible-light interference); 850nm suits applications that also require camera-based visual monitoring. Wavelength-bin matching is available for volume supply.
