"On the left is a replacement encoder which I obtained from Alesis for $4.00 USD. You'll have to email their support, who after several days will forward your email to someone who can help you, who will then ask that you send your credit card details via unencrypted emails. I suggest inquiring about paying with a money order.On the right is an encoder I obtained from Newark for $1.09 USD. (I ordered ten, so I got the price break.) Newark will request unnecessary personal information and send you several pieces of spam even before your parts arrive. I suggest that you use a disposable email address.
In the center is one U.S. penny, for size comparison."

ReplyDeletethat is art
ReplyDeletei need to know what exactly this thing is. my knob broke.
ReplyDeleteThe actual part from Alesis appears to be BI Technologies EN11-HSM1AF15.

ReplyDeleteI tried using the stated part.. The only problem with it is that the side lugs are too large to drop into the holes in the board, and the other issue is that the grey code is reversed from what the original Alesis encoder uses. This makes the knob run "backwards" during use. i.e., to turn something down you have to rotate the knob clockwise.
Looking through the Bi Tech site and reading the PDFs, it looks like the EN12-HS22AF20 is a better match. It has the 24 detents like the original, has a plastic shaft like the original, has slightly smaller lugs to fit in the holes on the board, and also has the proper grey code (reversed from the one you posted up) On the other hand, it is plastic, and my friend doesn't seem to mind the backwards directionals if he gets to keep a metal shaft, as he's a bit rough on his equipment.
The parts can be found at Mouser.com for about $1.50 apiece.
