euchner encoder type

[gttool]

Have an existing spindle encoder off the the back of my Harrison (fanuc) lathe
It is a Euchner brand but have not been able to find any info on it
Part number is P58HSLDB1 1024-533-05R3
10 wires connected to the plug ?
Googling does not give any usable results
Does anyone know if it is reusable or have pinouts ( oak )

If the 10-pin connector is an 18-1 pattern military-style connector, then there is a reasonably consistent standard for those.

For example, see: https://www.usdigital.com/products/enco ... haft/hd25/
or: https://www.automationdirect.com/adc/sh ... n1024vwdms
... and look up the pin-out for the 10-pin connector.

Encoder has a flying lead with a multipin fanuc scuzi type connector 10 pins populated
I have the machine wiring diagram but it's completely different to what's there

Encoder

With some effort, you may be able to puzzle out the connections.

Is the cable integral to the encoder? I.e. on the side we cannot see in your picture, does it enter through a strain relief, vs. having a plug?

If you cut the wires off the old plug, remove the strain-relief clamp, and strip the jacket back a short distance, you can tell whether the wires are twisted together in pairs? If so, and if it is a differential quadrature encoder, then you can reasonably assume that four of the pairs are (+5V, 0V), (A, /A), (B, /B), and (Z, /Z). If there is a pair that has WHT and BRN, or BRN and BLU, or RED and BLK, those would be likely choices for the 5V power pair.

If you apply 5VDC to what you think is the 5V power pair, then measure voltage across the other pairs, you can see whether they look like line-driver outputs: one wire of each pair between 0.3 and 0.7V above common; the other wire of each pair between 3V and 4V above common; so plus or minus around 3V across each pair.

You do risk damaging the encoder doing that type of experiment, but if your only alternative is to buy a new encoder with a known interface, then there is little to lose.

Thanks for the advice
enters through a strain relief ,
Probably dont have anything to loose if I try that approach
there is a what looks like 5 pairs of wires ( never considered that yes the wire should be twisted pair )
will see what i measure across the pairs - i didnt know what voltage I should see ,so thanks

Maybe they kept the same color coding for their manual pulse generators:

Cable was not twisted pair
Unriveted the case and pics below
Did put power on it but didn't seem usable

It might be dead. If it were in working order, it would probably be usable.

The DS8830 / SN75183N chip is a two-channel differential line driver. Three channels are needed for the encoder. Maybe the chip hidden behind the wires in your top view picture is a second two-channel chip.

If you can follow the traces, you could identify the Vcc (+5V) and "GND" (0V) wires, because Vcc should go to pin 14 of the chip(s), and GND should go to pin 7 of the chip(s).

The line driver outputs would come from pins 5 and 6, and from pins 8 and 9.
