_ Supply infrared receiver infrared receiver infrared receiver on the tube _ _ Strong Optical Digital Production Co., Ltd. Prudential Merchant 

 Shenzhen Cheng infrared receiver manufacturers Coretronic Digital Co., Ltd. has been established since 1999, the company to expand and continuously improve internal mechanism, the business sector in the country authorized to obtain a business license and tax registration certificate, the production and manufacture of various types infrared receiver products have made the EU ROSH environmental certification, ISO9001: 2008 quality system certification, SGS product certification, more part of the infrared receiver was patented product ... ... a wide variety of product certification confirms our production and infrared receiver the strength and quality. Market competition in the future, we will continue to work beyond existing results, to produce more high-quality infrared receiver. 
 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, and 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 low prices, 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.
