Re: AMT103 encoder ground *WARNING*

A pair of plastic components isolates the shaft from the main body of the encoder, and I think the part they interface with is also plastic. I do not believe there is any risk of an accidental electrical connection that way.

I've just discovered you can order replacements backs and sleeves for the encoders separately, which will hopefully help.
We're using the "snow" (white) one for 1/4" (6.35 mm) shafts. Red sleeves are only 6 mm.

We determined almost immediately that the encoder bases are too fragile to reuse. Of the ten we started with, only two survived having the encoder removed without at least one of the three clips breaking. CUI pointed us to the "naked" encoder base in the Digi-Key catalog:

http://www.digikey.com/product-detai...322-ND/4835233

From that starting point, we found many individual parts that might come in handy. Digi-Key search URLs are not persistent, so I can't copy and paste here, but you should be able to navigate to Product Index > Sensors, Transducers > Accessories and choose CUI Inc from the Manufacturer list.
