NPN TO PNP Circuit

  1. May 20, 2012 #1
    Hello All,

    I have a sensor which outputs an NPN signal, however, the gauge it connects to only inputs PNP signals, how can i convert the NPN to PNP?

    I have tried looking for circuit diagrams and simple converters but I have found nothing, all help appreciate.

    Thanks

    Very nebulously phrased question. Got a diagram of the two circuits?

    Basically, the NPN sensor has three wires coming out of it and the guage had an input of three wires, however, the gauge requires PNP not NPN, so i need to convet the NPN to output PNP

    It's a case of really truly needing to see the circuit!!
