I've looked at encoders which I believe are used in the uBITX .? Perhaps you need one, they can be blown up with incorrect hookups, or physically just bad. Or perhaps your doing a special project and need one.?
Of course, the encoder supplied with a uBITX is kind of a special animal.?
It has the following specs. or close to it. There are a couple of important details, one the Number of Detent, and the Important spec is "without" and? , a few do not have switches and a few details like that. The link for a table showing these specs is here.?
And here is the encoder I believe to be almost exactly what we use in the Raduino .?
Now, if you try to get encoders, its really tough on ebay. Most of the details are left out. And, my experience with some listings is that if they give the details, it will be a very expensive item.? Here for example.?
From England,? GPB 8.99 $12.67 US Dollars for ONE !?
Most of the ebay listings are like this one. Cheap, but no details.
And, you will be very disappointed because one of the most important details is the encoder is the "number of detents" which should say "without". Detents are the physical click you feel when you turn it, uBITX encoders are smooth, no detents, and Alps says "without" to describe this feature. Encoders with Detents are terrible for the uBITX.? And most likely the ones supplied by Ebay will have detents.?
?And Amazon doesn't give any details either.?
I am told these would be like the ones the uBITX uses.?
But, I'm not sure how the person who referred this to me knew that. Definitely not from the listing. Was he just? lucky ??

Of all of those links, only the last one is any good. All of the others do not have a threaded shaft, which most people will want. I've probably purchased 50 KY-40 encoders and all have worked well. I haven't used them all, so there may be a bad one lurking in the pile, but so far, so good. These do have a detent, but another post here showed how to make it "detentless". Personally I like the detent as it stops on a dime and there is no coasting.

Humm, cool, one detail I hadn't looked at. Narrows the choices a little more. And also is one more detail the Chinese don't offer.

Don't forget most of the Chinese KY-040 encoders do not include a nut to mount them.? M7x0.75 nuts are like unicorns around here.? I ended up ordering some from Jameco.

Well, it seems my esteemed buddy, Don, might have a good recommendation from Amazon after all. And does seem to include a nut and washer for each . A good deal. Worth checking out.?

And don’t depend on the picture to represent whether the mounting shaft is threaded or not.? Best to ask first but probably still no guarantee.? Ebay guarantee seems to work if parts are not as shown. Mike K5ESS ?

I wish they (Chinese ebay sellers) were a little easier to communicate with. The generally send this pre-packaged reply which says " We do not care about that detail" ! There is one, called Alice with some numbers, that may communicate a little easier.?
