Re: S4 Encoder Group Buy
 

Put 4536 down for 1 encoder and 1 cable. We'll play around with it, and if they are as magical as you make them seem, we might take a few more in the next group order. :p

Re: S4 Encoder Group Buy
 

I set up a quick vi to run and sample the output of the encoders we ended up purchasing from Sparkfun.

Adam specifically wanted to know ho well they operated in the 2000 RPM range as well as if they became warm due to the very minor resistance to rotation they have.

These encoders are rated up to 5000 RPM. We tested them at just over 2500 RPM. They ran continuously for over 20 minutes during the tests and never got warmer than room temperature.

Below is a graph of the A and B channels. The slight fluctuation is attributed to the mechanical set up used to drive the encoder. As you can see, it was a bit janky, but it worked.

Please put 3502 down for 4 encoders and 4 cables.
Thanks!

Re: S4 Encoder Group Buy
 

Please allocate 6 for Team 2135--no cables needed.

Thanks

Re: S4 Encoder Group Buy
 

3081 - 4 encoders, 4 cables.

Re: S4 Encoder Group Buy
 

We'd be interested if it's 360 count. Why the lower count?

Re: S4 Encoder Group Buy
 

Put us down for 4 encoders & 6 cables

Re: S4 Encoder Group Buy
 

They want to be consistent between what they are ordering. They also plan on running them at higher speeds so the 120 is better for that application.

Re: S4 Encoder Group Buy
 

Put 2202 down for 2 encoders and 2 cables.

Thanks.
I will need an invoice (email should be ok), and we can mail you a check.

PS: If you get another order or two, you should be at 50+ level, and can get the 100+ pricing. What would that be?

Re: S4 Encoder Group Buy
 

^^Accurate

Here is what we have for orders:
2175 - 6 encoders, 12 cables
3130 - 6 encoders, 12 cables
3883 - 6 encoders, 6 cables
4607 - 6 encoders, 10 cables
4536 - 1 encoder, 1 cables
3502 - 4 encoders, 4 cables
2135 - 6 encoders
3081 - 4 encoders, 4 cables
3847 - 4 encoders, 6 cables
4334 - 4 encoders, 6 cables
2202 - 2 encoders, 2 cables

Total Encoders: 49
Total Cables: 63

Re: S4 Encoder Group Buy
 

if you are that close to 50, we can take one more of each.

Re: S4 Encoder Group Buy
 

With that order we now are up to 50 encoders, so we qualify for the next price break!

Re: S4 Encoder Group Buy
 

If it's not too late, you can put 1736 down for 2 encoders and 2 cables.

Re: S4 Encoder Group Buy
 

How fast are you running them that you are having issues? We've run them pretty fast w/o issue.

It's a bummer because you're giving up resolution for free.

Re: S4 Encoder Group Buy
 

Out of curiosity, how fast have you run the 360 click encoder before?
