Dual trimmer/preset pots?

Tue Mar 30, 2010 10:25 am   

Do they exist? I don't think I ever saw one, and can't find one so far on
Digikey. I'm trying to avoid using a dual pot IC to solve this. An off-board
dual pot is practical, but not as small and neat as I want.

We do have trimmer. By the way, can you tell us detail of the Dual
trimmer/preset pots request ?

Multi-section Bourns 81/2 5/8" pots with PCB pins and slotted shaft?

Eg. http://www.bourns.com/data/global/PDFs/8182.pdf

But cost will be maybe +10 dB over that of a couple of decent cermet
trimmers.

Thankyou. I like those, I might go for them or the tagged version. It's for a
laser driver board where taking the business out to a chassis mounted pot
might be better than using a preset as the dual control will set a threshold
for lasing but can also be used as a manual fader in absence of modulation
input. If the thing really has to be small and hidden away I will probably
settle for fixed resistors to set divider ratios, as they have to be equal.
