Ametek 600oz/in 965922 motor encoder??

Greetings,

I recently ordered some Ametek servo motors. These are the
green 600oz/in variety. They are models:

965922-101 (1 5/16 shaft)

965922-102 ( 1 7/8 shaft)

Both motors have a 3/16 diameter by 3/8 long encoder mounting
shaft. I purchased then at www.candhsales.com, stock number
DCM9951 and DCM9951A.

If anyone has these motors, I would appreciate a part number
and source for the encoders you are using. I am looking to
get the encoders at www.usdigital.com.

Thanks,

Eric
