Potentiometer Identification

[Peter9DO]

So, I have this Potentiometer (which I think is a digital Pot) that I took off of a broken factory car radio. I though it would be nice and easy to find a data sheet on it and be able to use it on a project I'm working on. Needless to say I can't find it anywhere. Can anyone help, I added a couple of pictures I don't know how much they will help. There were some ID marks on it as followed:

Side: 15740
Side: 21-34
Bottom: JPN
Bottom: It almost looks like a "M" that has that curls or the sigma symbol, turned to look like it's an "M" and it's in a box. Along with an "F" on the other side

Well, any help you can provide, I would be most grateful!

Thanks guys,
Peter

I've seen pots with a two-digit code instead of a three-digit code for resistance.
For example, a code of "24" is 2 with four zeros, which is equivalent to 20K.

I forgot to say, some "pots" may be shaft encoders.
A shaft encoder can do a full 360 degree turn (and beyond) without any stops; potentiometers can go around 270 degrees from start to finish.

Nice! Thank you for the information! I took a look at that data sheet, I wish it was more in detail as to what the leads are. Other than the COM, I pretty confused as to how to hook it up properly.
