Re: Encoder details from various suppliers
|
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.

Subject: [BITX20] Encoder details from various suppliers
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 ??
