Multiturn Wirewound Potentiometer with Dial

I've never seen this type of dial, so I thought this might be very useful when one needs to return a potentiometer back to an exact value.
I got it from eBay, from a seller called: delhanway2009
Product links change all the time, so if you want one, just search with these keywords: Scientific 10K Ohm 3590S-2-103L Count Rotary Wirewound Potentiometer Pot 10 Turn

I’m adding these to my laser! I needed to understand better what they are. Thank you!

This would be amazing for adjusting the negative feedback on a tube guitar amp. And a high school locker knob to boot!

Just what I needed - thank you for sharing this.

I have an old Beckman "Helipot" from the 50's with this kind of dial. It has 15 turns, but it's otherwise a lot similar. A bit bigger and more solid though.

I just got an analog oscilloscope that has one of these. Pretty nifty.

Hi
Thanks for the useful video👌
I want to use the micrometer limit switch that is applicable to the hydraulic hose crimping machine, and it uses Vishay Turn Dial
Please help if it is possible for you

Bagus potensinya 👍

How does it mount

[@michaelbooth4289]

What is the black tab for? Locking tab? Thanks

[@pavanindustries9861]

That's for locking the spindle for accidental change in setting.

How does the multi turn work differently compared to a single turn potentiometer. How does it keep changing the resistance for multiple turns?

[@pompeymonkey3271]

It has a spiral track! :)

[@theofficialjizzy]

Thats actually ingenious

Hi, I just bought two bourns one.When I measured ohm via multimeter it works perfect. Then I added with my arduino board but it did not work. Then I again tested via multimeter but it is not showing any resistance. Do you have any idea why??

[@pavanindustries9861]

Is it genuine Bourns? market is flooded with counterfeit products manufactured in China. People loose money and waste precious technical man hour due to this.

[@tbiowa9977]

Why not show how to wire it for those that do not know?

[@Fluvance]

Potentiometers are very basic. If you need a tutorial, there are thousands of videos and guides online.

Show us how to lock
