2" ≈ 5.1 centimetres

Yes, if the box is specially designed for that. --------> certain junction boxes will accept an insulated plastic partition between the low voltage stuff and the regular 120v. It basically turns one box into two.

Do an amazon search: here's the first one that pops up: "Southwire MSBMMT2G Two Device Adjustable Depth, Heavy Duty 42lb Screws Included 2-Gang Multi-Mount Electrical Box, Gray"

You need a dual voltage box.

The National Electric Code should have your answer
USSBigBooty
Yep. Definitely. Done it many times before.

No. Just do 2 boxes. They're pretty cheap.

This guy is right. Boxes are cheap and easy to put in.

My understanding is that both low- and high-voltage lines should not intersect in the same junction box because there's the possibility that the latter will touch the former. But then again, I'm not an electrician.

Live wires produce magnetic fields, the fields can cause small fluctuations in other nearby wires fields, with more power meaning a stronger field. Low voltage is generally some sort of signal wire and high voltage is power.
The high voltage field can sort of overwrite the low voltage and when you need a precise signal that can be an issue. You can see it by running a power cable pass a speaker wire or a screen cable if you want. (It's not permanent just have to separate the fields)

Sorry pal. You can't run low and high-voltage in the same box and be up to code. If you don't care about code, then please make sure your low-voltage cable and it's terminations are shielded, at least.

I keep reading the opposite as long as they aren't ran together in the same conduit and/or remain 2 inches apart. Just found a pdf from Lutron saying the same thing

In the plants I run signal and power in the same cable tray all the time, just has to have a divider. Though we do prefer separate trays. So I can't imagine a gang box being a big issue but yes check the NEC. You can download it. It's a bit wonky at first but a little effort and you can find what you need

While you may be technically correct, that code amendment is really meant for certain cabinets like elevator controls, security control panels, and the like. Good luck ever getting any inspector to approve what you have in mind.
LitterBoxKing
Yes, but they cannot be guaranteed to be 2" apart inside the junction box.

You can if there is a barrier in the box, basically separating it into 2. At least in Canada.
