The infrared receiving tube is a device that directly converts electrical energy into near-infrared light and belongs to the diode category. Its structure and principle are similar to those of general light-emitting diodes, except that the semiconductor materials are different. The infrared receiving head is a receiving, amplifying, and demodulating device. The internal integrated circuit has completed the demodulation and the output is a digital signal. The infrared receiving head consists of two parts: IC and PD. IC is the processing element of the receiving head, mainly composed of silicon crystals and circuits. It is a highly integrated device. PD is a photodiode, and its main function is to receive light signals. Infrared reception needs to be demodulated first, and the demodulation process is received through the infrared receiving tube. Its basic working process is: when the infrared receiving module receives the modulated signal, it outputs a high level, otherwise it outputs a low level, which is the reverse process of modulation. The original data signal output by the infrared receiving head is exactly the opposite of the transmitting end. That is, if the original signal of the transmitting end was at a high level before, then the output of the receiving head is a low level. On the contrary, the signal sent by the infrared remote control is a series of binary pulse codes. In order to prevent it from being interfered with by other infrared signals during wireless transmission, it is usually modulated on a specific carrier frequency - 38kHZ and then transmitted through an infrared emitting diode. The infrared sensor integrates receiving and modulating infrared rays. The infrared receiving device must filter out other clutter, receive the signal of the specific frequency and restore it to a binary pulse code, which is demodulation.

Faster shipping times to Western and Eastern Europe apply only to products marked as "Product Inventory Location: Germany" on the product page. If the product is not labeled with this location, it will ship from our Chinese warehouse following the corresponding shipping schedule above.
Whether shipped from Germany or China, we cover all import duties and taxes, ensuring that you receive your package without any additional costs or hassles with customs.
Please verify the inventory location on the product page before placing your order to confirm delivery timeframes. For any questions or further assistance, feel free to contact us!
Our products are stored in both our Shenzhen and German warehouses to provide more flexible logistics solutions tailored to different regions and customer needs. On each product's description page, we indicate the specific warehouse location to help you better plan your purchase and delivery schedule.
For products stored in our warehouse in Germany, we use either Deutsche Post or DHL for shipping, depending on the size of the package. Logistics within Germany are very efficient, with an estimated delivery time of 2-4 business days, ensuring you receive your order quickly and conveniently.
Products shipped from our Chinese warehouse are handled by YunExpress. Given the complexities of international shipping, the estimated delivery time for these packages is around 10 business days, though this may vary slightly due to customs processes or other uncontrollable factors.
To ensure that your order is delivered within your desired timeframe, we recommend reviewing the warehouse information provided on the product pages before placing your order and selecting the appropriate shipping option. If you have any questions or need further assistance, please don't hesitate to contact our customer support team—we are here to help you!
Please note that it may take 1-2 working days for Deutsche Post, DHL, YunExpress, and 4PX services to update the status from 'Shipped' to 'Traceable'.
