Power
Ground OR Signal Power Signal Output Depends what they are using for the sensor. But as Mr Gaza says the wires have got to work as wires so they need testing no matter what the sensor is doing. I know that your gagging to know the difference between two and three wire sensors like this so ... 2-wire sensors are operated in series to the connected load. There are no separate connections for the load circuit and the voltage supply of a 2-wire sensor. So it is acting like a switch. ON OFF ON OFF 3-wire sensors are sourcing, type "PNP", or sinking, type "NPN", with separate connections for the power supply and for the output. So it has a seperate supply on the load wire. A bit like a transistor but still works like a switch. ON OFF ON OFF Knowing isn't often a great help LOL
