 Guarantee the quality, stable performance, low price, good service has always been the first customers on the use of infrared receiver product requirements, Cheng Coretronic Shenzhen Digital Co., Ltd. with unique technology, strong strength, years of experience to ensure the production of infrared receiver quality assurance, performance, stability, low price and good service, and serve customers in every industry to provide the best field of the infrared receiver. 

 The structure of the infrared receiver description: 

 Infrared receiver infrared receiver circuit is usually composed of diodes and amplifier circuit, amplifier circuit usually consists of a manifold and has a number of resistors and capacitors and other components, and needs to be encapsulated in a metal shielding box, and thus more complex circuit, the volume is very small, but also A large volume of less than 7805! 

 SFH506-38 and RPM-638 is a special kind of infrared receiver circuit, it infrared receiver and amplifier circuit integrated in one, small size (the size of a medium power transistor equivalent), good sealing, high sensitivity, and the price low, the market price is only a few dollars. It has only three pins, respectively, the power supply positive, negative power supply and signal output, and its working voltage is about 5V. As long as it is connected to the power of a complete infrared receiver amplifier, easy to use. 

 Its main features include amplification, frequency selection and demodulation of several parts, requires the input signal has been modulated to be a signal. After amplification and demodulation of the reception it will be directly output at the output the original signal. Thereby simplifying the circuit to achieve the best! Sensitivity and immunity are very good, can be a perfect device to receive infrared signals.
