Hi,
Is there a way to increase the physical turn resistance in a rotary encoder? The ones I have from ebay turn too easily, I want to get a more robust click feeling, as an old amp volume pot. Either that or maybe anyone can recommend me one rotary that is "solid" and I can get from Mouser.
Thank you

I can't see that being easy to add to a potentiometer or encoder shaft.
I've just searched on e-bay and you can buy encoders with detent springs. rotary encoder with detent | eBay

Hey, thank you both, and sorry for now having been clear, I don't know how to explain it better, excuse my english. My encoders already have detents, they do click while turning. The problem is they turn too easy, as if the detents were too short and make very few (physical) resistance.
The usual way is for the factory to use heavy grease in the bushing.
You could experiment with stiff grease cut with a solvent so it will seep into the bushing then dry and go stiff. I would expect trouble with grease in bad places or solvent eating plastic.
For add-on damping there is the FDT-47 series.

Often helps to use a HEAVY knob. Radios used to mount a flywheel, a few-inch lead disk. Fancy hi-fi uses BIG volume knobs for similar effect.
A felt disk behind the knob adds drag but very variable.

The grease used on tape deck doors clutches that open slowly would be a good candidate, and that type would be ???
One time I cleaned the grease on my Pioneer record player and it wouldn't descend the arm slowly, so I went to a bearings shop and asked for a stiff grease. I tested it on my fingers and seemed to work well. Applied it on the shaft and it worked. You can also try a RC car shop, as they usually have silicones and greases of different grades for the shock absorbers. Believe me I've tried vaselines, araldite (only 1 tube content at a time), greases with baby powder mixtures for stiffening etc and all of them were too splippery)

Bourns EM14 Optical Rotary encoders have a very nice feel to them and the ones with detent have a nice 'click'. They are pretty expensive though.
hey I'd missed this one, thank you!
Also seen some encoders have "High Torque Version to Emphasize Rotational Feel" as a feature, for instance Grayhill SERIES 62A,V,D. A pity this is not a feature I can filter products by, at least at Mouser.
