That should have the big black plastic, analog encoder. I have seen the little digital encoder on these when we pick up new jobs. I think they are 500 cpr, DMC won't save a travel that high. I have also got way high travel #s replacing the analog encoder switches with Sees parts, I know it doesn't make sense but it worked fine with TK parts. If anyone else has seen that or can explain it I would appreciate hearing about it.
