SUMMARY

The discussion focuses on converting an NPN signal from a sensor to a PNP signal for compatibility with a gauge. The user seeks circuit diagrams and simple converter solutions to achieve this conversion. The NPN sensor has three wires, while the PNP gauge also requires three wires for proper operation. A clear circuit diagram is essential for understanding the conversion process.

PREREQUISITES
  • Understanding of NPN and PNP transistor configurations
  • Basic knowledge of electronic circuit design
  • Familiarity with wiring diagrams and signal flow
  • Experience with sensor and gauge integration
NEXT STEPS
  • Research circuit diagrams for NPN to PNP signal conversion
  • Learn about transistor switching and interfacing techniques
  • Explore the use of opto-isolators for signal conversion
  • Investigate common components used in signal conversion circuits
USEFUL FOR

Electronics enthusiasts, circuit designers, and engineers working with sensor and gauge systems requiring signal compatibility.

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 gauge 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!
