Molded Through-Hole Infrared Receiver Module A 3-pin through-hole (DIP) infrared remote-control receiver with a 38kHz carrier frequency, an integrated PIN photodiode and a preamplifier/demodulator IC. It offers strong interference resistance and directly outputs active-low TTL-level signals. Operating voltage is 2.7~5.5V, quiescent current 0.4~1.5mA, reception distance 10~15m and reception angle ±45°. It is a general-purpose standard component for remote reception in TVs, air conditioners, audio systems, set-top boxes and other appliances. Supplied directly by Dongguan Hongcheng Optoelectronics Co., Ltd. (an international member of Guangyu Group, with over 20 years of LED packaging experience). Uses A-grade chips and 99.99% pure gold wire bonding, with RoHS certification. Datasheets are available for both the standard version and the version that passed a 96H salt-spray test. Free samples and custom lead lengths, reception angles and carrier frequencies are available. Download the datasheet PDF on this page for complete electrical specifications.
Q: What is the difference between an infrared receiver module and an infrared receiving diode/transistor?
A: The receiver module contains an amplifier/demodulator IC and directly outputs digital signals demodulated from 38kHz, ready for remote-control reception once connected. A photodetector (photodiode) outputs only a weak photocurrent and requires an external amplification/demodulation circuit, mainly for through-beam or reflective sensing.
📄 Datasheet Version: Two versions are available: the standard 'Molded Infrared Receiver Module Product Datasheet' and the 'Molded Infrared Receiver Module, 96H Salt Spray Test Version.' The salt-spray version suits outdoor equipment and bathroom sensing products in coastal environments with high humidity and heavy salt spray. Both can be downloaded free from the datasheet download center.
Q: Which emitter should be paired with a 38kHz infrared receiver?
A: Use a matching 940nm infrared emitter (IR LED), driven with 38kHz carrier modulation at the transmitter. The receiver module includes amplification and demodulation and can output digital signals directly to the main controller. We can also provide matching 940nm emitter models and reference driver circuits.
