3 WIRE CONNECTION DIAGRAM BANNER PNP NPN
What is the difference between PNP and NPN when describing
Two specific types of 3 wire sensors are available; PNP and NPN. The difference is a result of the internal circuit design and type of transistors used. A key point to observe is that PNP and NPN has nothing to do with whether the sensor is normally open (N/O) or normally closed (N/C), i.e. a PNP sensor may be either N/O or N/C as can an NPN be either N/O or N/C.
An Easy Way to Remember PNP and NPN Sensor Wiring
Here’s a simple way remember how to wire up a 3-wire DC PNP or NPN sensor: PNP = Switched Positive NPN = Switched Negative “Switched” refers to which side of the controlled load (relay, small indicator, PLC input) is being switched electrically. Either the load is connected to Negative and the Positive is switched (PNP), Continue reading "An Easy Way to Remember PNP and NPN Sensor
Industrial Sensing Fundamentals – Back to the Basics: NPN
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.

DIFFERENCES BETWEEN PNP AND NPN
PDF fileDIFFERENCES BETWEEN PNP AND NPN The concept PNP and NPN is something that we will find throughout our professional life in many occa-sions, when we have to select a detector or three-wire photocell, when selecting a PLC, and especially at the time of design schemes and wiring.

Two Wire Inductive Proximity Sensors: The Universal Donor
In figure 2, we see the circuit diagram for the 2-wire variation. The output operation is along the two power wires in the form of a voltage drop, thus making the sensor free to work with either polarity on the common. Replace NPN and PNP 3-wire models. Because of this, you can use the 2-wire sensor to replace both the NPN and PNP 3-wire models
Control Wiring - Sinking and Sourcing, NPN-PNP Devices and
In the video to the right we explain what a Sinking and Sourcing PLC input is, the fact that manufacturers are not consistent with the use of these terms, how they equate to NPN and PNP sensors, and most importantly how to look in the PLC user manual and determine how to wire your control circuit based off of the manufacturer's wiring diagram.
