I am expanding my phi-panel keypad options and purchased a bunch of rotary encoders. They look like this:
My question is: since it has pcb pins on the bottom, why does it also have screw too? I can't think of a clear advantage of using them both? Will that be a small PCB the encoder is soldered to and then the encoder is mounted behind a panel with the screw. Then the wires from the small PCB can go to a main PCB?

Yes, just allows the designer more choices for where to mount the encoder Vs where the main logic board is placed.
Thanks for the quick answer. I think I might just pursue that route. My drilling skill with a dremel is pretty basic without a Dremel drill press stand. So if I drill a hole on the top cover of a project box, then do the panel mounting with a small PCB, I could then wire wrap the small PCB to my main logic board. Easy enough. If I did 3 buttons layout (up/down/enter) instead, I bet I'll mess up the last hole LOL

Heck if working with plastic project boxes I just plunge my hot soldering iron into it to make a small hole and then use a small hand reamer tool to make the hole the required size. If it's a metal case I of course first drill a small hole and then use the reamer tool. My projects lean towards the functional side rather then the nice cosmetic side.
Thanks Lefty! I'll get myself one of those. The dremel is a really dangerous piece of rotary tool. I might have to get a drill press stand for it. Drill small holes with it and open them up with a reamer.

Don't forget the hole for the little metal tab on the front. That's to stop it from turning when the user twists the knob.
That's right. I forgot to mention that. So easy to just draw it on a computer for laser cutting. I'll have to tape a 1:1 printout of the layout before I drill

I got one of those last Xmas* ... the problem is you can't really get any decent size drill bits for it. The biggest bit I could find that fits in a Dremel chuck was 6mm. I might have to get one of those reamers...
My girlfriend bought it for me, this year she's getting a bandsaw in return (but don't tell her!)

Are you using the keyless chuck for Dremel? I didn't test but the keyless chuck can adapt to some slightly largish drill bits. Maybe 6mm is its maximum. I'll get a reamer too. Glad to know both you and your girlfriend like machine tools.
