I'm kind of new to this, so I'm not sure exactly what you're looking for.

What is a "classic quadrature incremental, 50 ppr, volume control encoder"? Is this a "rotary encoder" type of switch as can be found at www.Digikey.com ? Does it have pulsed, Gray or BCD coded output?

It might help you to find what you're looking for if people understand what exactly it is. ( Or I might be the only one that doesn't understand. But I would still like to learn what it is. )

Regards,

Tom

yes, rotary, with pulse output, 3 wire plus 2 for supply, 50cpr means 50 pulses per revolution(at least), something like this...

Those look expensive!

Have you considered using relatively inexpensive, encoders that are intended for commercial audio use, such as the Grayhill Series 62P or the mechanical Series 25L which can be seen at

http://dkc3.digikey.com/PDF/T062/1515.pdf

and are less than $6 USD? Or is there something you specifically are looking for?

yes, the cheapest are 6$...but if you want something that will give you a good smooth sensation when you turn it, you need something more solid, metal casing first...in my head there's something used in cnc industrial machines, heavy and...expensive!!
