Recommanded Asolute Encoder Brand.

[dani90]

Any of you would recommend a brand for absolute encoder on a drive shaft.

Peter Natchwey is the one.

We, our customers, have had good luck with Sick. We mostly use the SSI versions as the parallel wiring is too expensive.

used to be photocraft encoders
used this alot in mhe areas

these i have used on a lot of servos.

I've used profinet/profibus versions from this company for years. Reliable and not too pricey.

If the encoder is being used to calculate a speed as well as position, the update rate should be synchronous to what ever is calculating the speed. Profibus is pretty fast but it isn't normally synchronous. However, sometimes it doesn't affect the application much.

I've used Sick encoders and Allen-Bradley Ethernet/IP encoders with good results. Hard to wrong with either brand really.

I've used Balluff SSI and they were pretty good.

Having worked mostly with AB systems, I've used AB and AMCI Ethernet/IP encoders. Both have done well in basic applications.

We've had good luck with Encoder Products Company. Lots of styles and mounting options.

This is a pretty ambiguous request.

First, do you mean single turn absolute or multiturn absolute? These are different beasts.

What will you be connecting the encoder to? What types of signals does it accept? SSI is mentioned a lot in this thread so far. Also Bus networks are possibilities as well as BiSS and EnDAt. Here's an article comparing some of these:
https://www.motioncontroltips.com/a...differences-between-ssi-biss-hiperface-endat/

Do you need to reach a certain resolution counts / revolution?

What is the environment like where the encoder will be installed?

What is the form factor required for the encoder; shaft output? hollow shaft, cable out the back, cable out the side, etc...

Norm!!!

Sick has plenty of options. So does Danaher.
Dynapar is OK too.
I just said Sick as my first choice because I/we have been working with them the longest. Back in the late 1990s a person from Stegmann posted on sci.engr.control about the new Stegmann SSI encoders. I was interested because for that there was only resolvers. I didn't like resolvers because every company had their own standards and the resolvers didn't respond well to fast accelerations. I/we jumped on the Stegmann resolvers. The SSI standard is now fairly standard. There are still some companies that mess things up by adding extra bits at the end. Sick ended up acquiring Stegmann.

What is the environment like where the encoder will be installed? wet and dust environment

hollow shaft
