Many people are concerned about the relationship between infrared emission tubes andInfrared receiver tubeEasy to mix up, sounds similar, but in practice, there are still significant differences in both appearance and internal structure.

Firstly, in terms of appearance, the biggest difference between them is that the infrared receiver tube has three legs, while the infrared transmitter tube has two legs. This is a well-known method that non industry professionals can distinguish at a glance.

So what are the differences in internal structure? You can continue to look below:

Infrared receiver tube (also known as infrared receiver module, IRM) is an IC module that integrates infrared receiver PD diode, amplifier, filter, and comparator output; The infrared receiver tube is an infrared detection diode that can only detect infrared signals and cannot amplify signals and subsequent processing. When using it, it is necessary to design an amplification circuit, which is also its weakness and can be said to be an advantage. That is, it can design exclusive circuits according to one's own needs.

Overall, apart from the obvious differences in appearance, the biggest difference between infrared receiving tubes and infrared transmitting tubes lies in whether they are integrated circuits or separately designed amplification circuits as needed
