RE: Re: Jog Dial - where can I buy ?

Dave,

I was just browsing and found the same part  :-)  Looking at the datasheet
I'm now unsure as to whether I'll get it to work with my limited
electronics knowledge. I was hoping to add each direction
"contact" and the push-button directly to a VIOM module. Is this
still possible as the datasheet starts talking about debounce circuits ?

I'm also unclear on is what's meant by the terms "detent" and
"quadrature" ?

I was after an "endless" rotary action. Now I know what I'm
looking for (i.e. encoders, thanks Patrick) CPC do sell plain encoders
(part of Farnell I guess).


Thanks,

Tim H.
(P.S. how expensive is "expensive" ?)
