YES! Turned off the light and I got 4.7v (no reflekt) and .71v (reflekt).
No I am going to mont it to my mill. It will be enclosed so no or little light vill be around.
Let you know how I am getting on.
For now, thanks again a lott. Without yours help I wouldn't have managed!

OK Thanks.
I tried it connected up, it is working!!!,- but I am getting the following readings: .71v and 1.26v.
What to do? Lover the 10K ohm resistor or the 150 ohm?
Well, I know, I could have tried different resistors but it is easier to ask

Yes you were right, my wiring was wrong. I have made a new wiring diagram witch I think is correct. Please comment. I have attached the diagram, but have not tried it jet.

I have now received some OPB607A sensors and have wired one as the diagram using R1 = 150 ohm and R2 = 10K ohm. I supply 5v and measured the voltage between earth and "signal out" to 1,3v with no reflector. The sensor do not react to a reflector at all,- no change on the reading.
Have I used wrong resistors, or have I blown the sensor?

Thanks OK. Mine goes to max 3500 rpm.

Thanks MN300.
I have 5v easy available at the mill, can this be used instead of the12v? Vil it cause problems?
The datasheet says that it operates over a broad range of supply voltages (4.5 V to 25V).

I have ordered both "hall effect sensor" and the OPB607A sensor but it will take some time before I get it, I will keep you informed.
In the meantime how is the wiring for the "hall sensor" and can I use the same resistors (150 ohm and 10 Kohm) for the optical solution using the OPB607A ?

AHA, that may be the problem. I have tested the OPB606A on the bench and get the reading 4,56 and 0,15 volt witch should be ok, but when installed in the machine the numbers in the RPM display in the Mach run page flickers. Also the green index button behaves unstable.
Will try to get a OPB607A. Or do you recommend a different solution?

TPS
Thanks a lott. Here is a lot of information, lucky I may find find a solution.
THANKS

The sensor is OPB606A and data is on the net. I have newly installed a new BOB from CNC4PC: C11GR9-S3578-46. I do not need information on how to mount the sensor, only the wiring.
