Acorn Spindle Encoder Basics

Yes exactly where I read that. Thanks for posting link.

Anybody have clear written instructions on installing encoder to SEM servo motor. Any warning out there on what I should not do or be careful of ? I have a 1991 Bridgeport V2XT. I've seen the tutorial, but I am sure a pic means one thing to one person and something else to another.

Ummm . . . I think I bought the wrong encoder - will this one work on an Acorn board?
Thanks very much for your help,

No
Go to Automationtechnologies.com, look for line driver differential encoder....
2000 line or better....

Im finding it hard to pin down the right encoder that isnt a chinese clone.

Could someone tell me if this is would be suitable

data sheet

I looks like it could be, but the signal voltages look low, after reading a post a couple of pages back.
any info would be helpful thanks.

No, that is a push/pull.
You want a Line Driver/Differential Encoder A, /A, B, /B, Z, /Z, COM, +5VDC

The URL is actually https://www.automationtechnologiesinc.com/

Automation Direct has a lot of choices and in my experience they are good quality encoders:

Thanks Marty its confused me as it says I can be wired for Push-Pull, RS422 or open collector. but i see no Z now. only 2 channelin differential mode.

I think europe uses different naming, for example, search "Line driver" in RS, or farnell and it comes up with a semi conductior rather than any kind of rotary encoder.

Anyway Ive found Koyo TRDA-2E2500VD in Europe. so that will do

for anyone else this side that might need one.

Line Driver = RS422
