I have an Inductive sensor model: BALLUFF. (BCC M323-0000-10-001-PX0334-020). i need to connect this to an external power supply with the DIY cable (red+ and black- ).
I found that Inductive sensor wire cable with 3-Pin (blue, brown and black) (showed in image). My question, i want to knew which colour of the wire is positive+ and negative (ground)- ?
