for clarity, 2 pins are 5v and ground. The 2 outputs output

Don't even know what these are called, and haven't found
anything similar so far.

Shaft encoders.

If you rotate the shaft at a constant rate, I think you get 2 triangle or sine waves out, 90 degrees apart.
(Haven't studied it very closely)

Since the device is being powered up and outputs a sine wave doesn't
that mean it must be powered with AC? If that's the case it sounds
like it may be a resolver.
