  • Keyence LR-ZH490CB Wiring

    Hey everyone,

    I've got a Click C0-00DR-D and I want to use a LR-ZH490CB Keyence Laser sensor as an input. I've got the wiring for the m12 connector as follows Blue to a separate terminal block supplied by the negative side of the 24vdc power supply for 0vdc. Brown to a separate terminal block supplied by 24Vdc positive again from the power supply. and the black to X1, but I m not sure where to put the white wire below are the diagrams. Do I nee the white wire and am I correct in how I have this?

      Depending on how the sensor is configured (assuming you do have it set for PNP output using the black wire for output), it seems the white can be either a remote setting input or "laser emission stop"
      There is a pretty good chance that you don't need to connect the white wire at all, but that will depend on how you configure the sensor
