What's the rotation encoder in the AX12

I saw it somewhere on the inet awhile back, but my google-fu is weak this evening.

For some reason I think it might be this..

That looks right from the servos we've taken apart. It's definitely a potentiometer and does have some jitter on it that we smooth in software.

I placed my digikey order today for a similar part. I guess I'll see.

I'm going to give a go at building a simple 3-axis CNC router ( for PCB's ) out of three AX12's in continuous mode driving some threaded rod. I'm going to add another encoder so I can get get a full 360degree of range. Fingers crossed that I can actually read back the angles when in continuous mode otherwise I'll have to double up the sensors.

I was worried that they'd not be continuous rotation, but they are!
