Seeking info on FANUC A860-0309-T302 spindle encoder

[RTech]

Continuing work on my lathe conversion, I would like to reuse the FANUC spindle encoder. Its part# is A860-0309-T302 and it looks like it has the correct number of wires, but I have yet to find information to verify this.

Any help is appreciated.

Unless you can get specs, have a wiring diagram showing connections, I would not bank on reusing the encoder.
Get a line driver/differential encoder from automationdirect.com or directly from Centroid(along with their encoder cable) and put the correct encoder on. You would need a Medium or better a heavy duty encoder to replace it, since the pulley is mounted to the shaft.

I found the info on the encoder after doing a lot of digging on Google.

It's a 1024 PPR encoder rated for 10k rpm with the following pin-outs:

A = A (PA)
B = Z (PZ)
C = B (PB)
H = +5VDC
K = 0VDC
N = /A (/PA)
P = /Z (/PZ)
R = /B (/PB)

Thought I'd record it here in case someone else needs the info in the future.

Looks right. Are you going to give it a go?

That should be an excellent encoder. Tough to find ones rated above 5Krpm. The mating Cannon connector should be easy to get from Digikey, Mouser, Newark/Element14.
