Yup. I thought that was the model but it's been nearly five years since I worked with them and I didn't want to provide false information.

One issue that was encountered was sensor alignment... it should be a no-brainer but one ought to make sure all the sensors are aligned the same (same 0/360 position)... on can calibrate in code and account for the 0/360 transition, sure, but it is a pain and can slow the processing down if not written well.

What makes this issue common is that the input shafts of the encoders, back then at least, had no reference mark and being continuous, there is no stop to reference to. In retrospect, the fix for this is to use a DMM to find the 0/360 point, and make a mark with a scribe on the end of the shaft and on the encoder body (or reference the first mark to a known spot on the body).
