if you are using them to as input to a PLC then I would look at these

i have used similar on a project that I needed the reference to reset to a known value for startup but they wanted the pot type controls
it worked great you just need to program an up down counter

Does it need to be with 22mm axle. Couple pop rivets and sheet metal for new hole?

GE had a 22mm panel mount pot operator in their C2000 series.
This came WITHOUT the pot and allowed you to select the pot resistance you required. It should work with a multi-turn pot.

Part number was P9CZ.
Since this product line has now been bought out by ABB you might try seeing if it is still available.

Are you using these with 5V input cards or are you building a small circuit to be able to use them with 24V?

I like the encoder Idear. No stops to hit. Thanks
The idear of a 22 or 30 mm was to have a factory built unit thinking it would hold up better then a standard pot and vernier dial.

If you look them up they are rated for 30VDC they are just a switch so you an use them on either voltage
I used them because I needed to be able to reset the speed when the motion stopped
On that project they were the speed reference of 2 VFD's to provide steering on a gantry
when the motion was stopped the differential speed was reset to 0
