need help for SAGEM optical encoder

[emilcnc]

Hello,
Can anybody help me to identify this encoder - how to wire and use it ?
Here is all info and pics that i collected for it.

If someone have the manual for it ... ...

If needed i will make better fotos .. excuse me for the low quality of the pics.

Text on PCB:
Down side:
23107544-2C/1
398007

4 opto diodes
LM339AN + LM348N - IC on PCB

15 pins to connect signals + 2 for light diodes

58 mm diameter of case

Text on PCB:
Up side:
C.I.E
23108315-5
23107543-9C

Thanks in advance !

Hello There,
I would be getting a datasheet for the two chips LM... and from there you can trace the power supply as stated by the data sheet back to the main conector of the PCB to show you where to connect the supply. Once you have supply on the board you should be able to find the pulsed outputs by moving the encoder while measuring the pins on the connector with a meter or even better a cro.

I hope this helps

Hello:
SAGEM is a french mark, try to search, but in possible that the wirig would be like a Baumer encoder, and manufactured by Baumer.

As suggested, You should be able to trace the supply wires fairly easily, the fact you have 15 connections and the amount of tracks it appears to have, indicates an encoder and with BLDC commutation tracks.
You can use the encoder independently, if you want to use the commutation you would need to decipher the pole count it is built for.

Hello,
I tryed to found informarion but with no success
Also the chips are powered from 2 ( 10 ) to 36 Volts ... maybe it is possible to increase the voltage and monitor the output pins but this is again problematic.
Maybe it will be a good idea to try to capture the schematics and diskuss the pins with expirienced electronics man ...
If someone find any info .... please share with me ..

Thanks

Hi there
I have a few of these devices, before I pulled them out I checked the power for them and to the best of my memory they require +/- 15 volt to operate. This is a bit of a pain so my plan was to take the photo diodes output into my own electronics board. There is no easy solution, It may be easer to get a known Encoder.,
