Hi guys,

I'm afraid PEC12 would be too small (12mm diameter, while we need
16mm). I used Bourns PEC164220FN0024. It has longer shaft, but it
doesn't matter a lot. If you want, you can see the photos here:

On the Bourns page there is an explanation of those numbers - you need
something that says "PEC1642XXFN0024", where:
 - PEC16 stands for model, 16 being the diameter;
 - 4 stands for horizontal terminal configuration (on EPR site they
say it should be vertical, which corresponds to value 2, but
surprisingly 4 works OK as well);
 - 2 stands for 24 detents (0 - no detents, 1 - 12 detents);
 - XX is the size of the shaft;
 - F is the shaft style, no options to chose from;
 - N stands for "no switch" (yes, you guessed, S stands for "switch");
 - last four digits determine the resolution - 0024 is the right one.

As I said, I used the 20mm one, but there are be 15mm available as
well, and the should fit better. I used the longer one, because I had
not enough time - only one week to find it, order it, have it
delivered and changed, as I asked my friend to do this, warned by the
message on the EPR Electronics site: "Please be advised that
replacement of this part requires a skilled technician with the
appropriate desoldering/soldering tools to safely remove the old part
(without damaging the pcb), and install the new part." In fact, you
only need some patience while disassembling the front panel, a
soldering gun with a fine tip and a tool to absorb the molten tin. I
saw it being changed and the whole operation took 30 minutes,
including jokes and word games.

Hope this helps all the owners of broken data dials, so crossposting
it to the P2K list as well, please don't beat me up!
