Thanks for sending the link. As I am in  mechanical engineering, I am not sure about some concepts. In page 41 / 484 of this catalogue, the followings are defined:

RED:   +   Excitation

BLACK:  - Excitation

GREEN:  -  Output

WHITE:   +   Output

For my case, red and white are connected together. So I am three wires other side: 1) White and Red, 2) Black, 3) Green.

Now, which of them is defined as ground, and which one is Negative? I think the white and red is positive.

For connecting it to the DAQ board, I need to know which one is positive, ground and negative.

Thank you in advance.

Do you have ant more information about the full model number?

Hi Michael,

Thank you for your support. I found the following info on the sensor:

SENSOTEC

FPG

Order No.: FPG1DN,2D5D6A

Part No.: 060-C798-03

Supply: 9-28 VDC

Output: 0-5 VDC

Two pictures are attached. Hope to be helpful to you.

Thanks again

There is something odd about this. Maybe the connector at the top was custom wired. Unscrew the black cap and take a photo of the cable connector (looking at the pins) and the transducer connector side by side. The red and white, since they are wired together, would seem to be the negative references (ground), but that contradicts the datasheet.

There are 6 wires on the transducer side. but only 4 wires (i.e. black, green, white, red) are in other side !!!!. Please see the following photos. Thanks for your time.

According to the datasheet:

A is the +Supply

B is the -Supply

C is the -Output 0 Vdc to 5 Vdc

D is the +Output

So Black is the positive supply,

White is the negative supply (ground),

Red is the negative output (ground),

and Green is the positive output.

This explains why the red and white are tied together, since they are both intended to be the common or ground. In the end, red and white are ground, black is the input voltage, and green is the output voltage. Here is the table from the datasheet:

You should double check this information before hooking it up, this only represents my opinion and I won't be liable if it gets wired wrong (I had to throw this in here to cover my butt).

Thank you so much. Really appreciate.

Your welcome. Label those wires for the next guy .

Sure. You are right.
