Freaks,

I have been searching for an SMD Potentiometer with a control shaft, and so far this is the best option I have come up with:

 

http://www.bourns.com/docs/Produ...

 

4.7k ohms resistance is ideal.  Very low voltage in the application.

 

Thing is that it is 7mm from the solder legs to the top of the case, which is really not that bad, but I would like to see if there is something similar out there, but with a smaller case.

 

Hence I am asking here if anyone has some suggestions.

 

Thanks,

Jim

Could it be an option to route a rectangular hole in the pcb and mount it from the bottom up?

That would make it the thickness of the PCB ( + thickness of the legs) lower.

You could even put 1 or 2 layers castellated pcb's in between as "filler" to get it real flat.

 

Just screwing it in a round hole in the pcb probably is no option (not smd).

 

Small tip:

putting a via through the solder pad makes them a lot stronger.

Nice for connectors and potmeters and such which are susceptible to mechanical load.

(But "oversize" the solder stencill or you will have not enough solder).

 

Anyway, fun to see a datasheet of a pot which can have 17 different "tapers" (From a1 through c6)

THought about that, but it does not save me any depth, which is what I am trying to reduce the enclosure of.

Just throwing in an idea, use a digital pot with either two push buttons or touch slider for setting value.

No can do.  MUST be a shaft mount...I should have thought about the digital approach before I had membrane overlays made up.

 

Ok  Time to keep looking

What about a digipot connected to a rotary encoder? Would that be compatible with your design?

@Kibok

THat first one is 2mm smaller than the one I was thinking of using...Great find!

 

THe second one would also work, but the overlay is already made so I am kinda stuck.

 

@El Tangas

I could certainly explore this if you have a rotary encoder you could suggest.

I was thinking something like:
