That's what I was not sure about them. And I can't find the manuals of these series so I can't check wheter I can wire them directly as TTL or if I need that interpolator box to make them work. There's another link with a gorgeous Allen Bradley encoder but they only have one. http://www.ebay.com/itm/ALLEN-BRADLEY-845H-SJDZ14DRY2C-Optical-Incremental-Encoder-5000-PPR-Type-4-13-/281274676932?hash=item417d46f6c4:g:w0gAAOxy0bRTDnbv Anyway my only doubt now is how much better are differential encoders compared to normal ones. I always used normal encoders with no signs of noise but since this is for a lathe with 0.01 mm increments I would like to go with the safest option.
