I recently got a nice office chair for Christmas with heated massage functionality and it uses a barrel plug to power it but I have to be super careful to not pull it or damage the barrel connector in any way. I wish there was a magnet conector for these things in case of a yank pull and was wondering if anyone had heard of some adapter like the one I pictured above.
Are electric barrel connectors ever used for data transfer? I've only seen them used for power, but I'm curious if it's possible.
No. They are indeed used for power only.
But technically you could use them for data or small signal.
If you consider analog audio as data, then yeah all the time
Hah, OK, got me there 🤣
