Hall sensors

[kal.a]

Hello everyone, I'm back with more questions and this time about hall sensors. I salvaged a magnetic/ hall **broken link removed**which basically **broken link removed** and a board, a housing and a disc containing the magnet/magnets. I could not find the datasheet as usual and have a few pictures of it.
**broken link removed** are connected to the two sensors and I figured them like as follows and hope for to confirm or reject my conclusion.

1-Brown is ground/common
2-Blue is V+ ( whatever that turns out to be)
3-White i signal
4-Green is signal.

Your help is as always much appreciated.

The normal connections for proximity etc, is Blue=common, Brown= +ve, Black= out1, White=out2.

You are absolutely right. My mistake. I reversed the blue and brown.

Thanks

what about black vs green?

Well, the way I figured it is that the white and green are on leads by themselves so they got to be the out signal and the brown and blue are each wired to a lead on each of the sensors so I figured the Brown and Blue are V+ and V- .
