That could be one of the serial encoders. I have several with the Kawasaki version of that (M21 encoders). They are small diameter (say about 1 1/2 inches) and only have four wires out (VCC, GND, Serial+, Serial -). Nice encoders, but the real pain in the tail is decoding the serial stream as it includes not only position (absolute position in the case of the M21), but also status and error information. Needless to say, the manufacturers usually are not too quick to release the details of the serial communications protocol.
