Im looking for an encoder disc 50mm OD, 12mm ID,
need about 50 slots, im tempted to make my own,
I need to arrange the two quadrature detectors to be on oposite
sides of the disc ~180' apart to offset bearing play.
at the moment I have one of the heds6100/9100 sets,
but they dont go down to 50cpr,
I need a lowish cpr in order for the quadrature signals to stay in a
quadrature fashion without needing super critical alignemt.
slots would only be 3mm pitch, so im contemplating makign my own as
ive not been able to find one.
anyone got any suggestions of sources or best way to make one?
im thinking maybe a reflective type opto and just a printed pattern on white
hmm and need something for the shaft mount ...
I posted a fine pitch model in abse the other day. All you would need
to do is use some opaque paint to blot out a few, and skip one, then a
few more, all the way around to make a low cpr version.
