Hello

Has anybody done it already ?
what type of encoder are in the racks ?

i am quite sure they r alps but i dont know the detailed specs
like the ppr resolutions

i am also quite sure that u can replace the EC12 (plastic tree) with the EC11 (metallic tree)

Any detailed info is appreciated
tnx Andrea

well in fact Access did replay to me very quickly and they told me that the correct part number is

ALPS EC16B 24 104 F 20

http://www.datasheetarchive.com/dl/D...ARS0024082.pdf

now i checked the web they r an old type hard to get
and also i do not want to replace them with the same cheap type
i want better ones with a metallic tree
but in fact any encoder 24 ppm should work
the only problem is that most of the new one are for panel mounting they are smaller
and they dont have the vertical mechanical fitting of the original ones

anyway the ec11 are smaller and they dont have 24 ppm

the ec12 do but they have plastic tree

i am also looking at some bourns ones but if u panel mount them then u have to
solder an extension lead from the pcb to the panel possible but bit complex to do

Another quick fix is to just spray a contact cleaner in the plastic tree wait till it goes inside and turn them many times
it helps a lot and i have done it already but i still dont like the shaking nature of the plastic tree
