I got an infrared led emitter, with model ""L1I0-0850060000000" and the datasheet is plenty of technical data but I can`t find why it has three terminals - 2 anodes and 1 catode. Usually it's used for data transmittion.
Here is the datasheet showing the three terminals:
I don't have many experience with light data links, but I know that some common leds have three terminals to allow switching the color. As far as I understand, this model is made for one specific infrared radiation - I could be wrong.
Has someone any idea on how to figure out this? I tried looking on google but cound't find a solid answer. I plan to use this for digital transmission.
