I forgot to mention I had those AMT encoders on my RF45 cnc mill. I must say that they seemed to work very well. Most remarably once I had built some nice aluminum enclosures for the encoders and had the wires running thru surgical tubing to protect them in the full flood coolant environment. well

I'm not actually answering your question; but have you looked at the shaft encoders on Ebay recently? There were some $15 units the last time I looked. It might make sense to adapt to some of those? $43 seems like a lot of money for the modular units considering what is delivered. Dave On

hello, all, I've been selling some Automation tech brushless DC motors with encoders to go with my servo amps. Lately I've been using HEDS-5640#A06 encoders from Avnet, which are the highest resolution I can get with a 1/4 shaft. There used to be inexpensive alternates from US Digital and
