Subject: US Digital E5 Differential Encoder
I'm looking at buying the US Digital E5 differential encoders.

Does anyone have anything good or bad to say about these concerning their performance and reliability?

Does anyone have a better recommendation (differential)?

I have the Kflop and Snapamp.

I was looking at the 500cpr units which would give me 30,000 counts per inch on my x and y, and 37,500 on my z. That is more than adequate for resolution.....but, is there any reason I might look for more or less counts based on anything else?

Does anyone know if the E5 enclosures are reasonably moisture proof?

This is for a mill that will be running flood, although the motors and encoders would not have any coolant allowed directly on them due to deflectors.

Thanks

I have used several of their encoders over the last few years, and have had no problems at all.
I have two E6's, used for steering feedback, in my radio-controlled vehicle crashing system. So far, each one has survived 6 crashes.
I've always found them great to deal with. Excellent tech support, too.
I wouldn't hesitate to recommend them.
They are not sealed, however. I would call them dust-tight. Check with their tech support, but I don't see any reason you couldn't seal the cover with some sealant. The cover also forms the shell for the connector, and that would be tricker to seal.

Thanks for the reply.....It looked like the plug area could be a problem. I may have to make supplementary covers, I guess.
