Industrial Sensing Fundamentals – Back to the Basics: NPN vs PNP

What’s the difference and why should anyone care? If you’re confused by the terms PNP and NPN, then hopefully this post will shed some light on the differences between the two.  In the context of this post, they refer to the construction of a sensor’s transistor and whether it has a p-type or n-type semiconductor. … Continue reading Industrial Sensing Fundamentals – Back to the Basics: NPN vs PNP
