No worries. The important thing here is that this module is simply reading a voltage from the sensor with reference to the ground of that sensor. This means that this module is always going to be a sinking device, and will be always be sinking small amounts of current from that sensor. This means, that your sensor is going to be powered externally and we will simply be reading the output voltage from it. Here is a link to a knowledgebase article about sinking and sourcing current. I hope this helps to clarify.
NPN and PNP transistors function in essentially the same way. The power supply polarities are simply reversed for each type. The only major difference between the two types is that the NPN transistor has a higher frequency response than the PNP-because electron flow is faster than hole flow. Therefore high frequency applications will utilize NPN transistors.

pnp answer
PNP and NPN. The NPN is easiest to manufacture and implement. Not really a third type is the Darlington Pair, but students tend to blush when they talk about it. It has a higher gain and is contructed from two NPN's.
The NPN transistor has its conduction curve where the base is more positive than the emitter, while the collector is also more positive than the emitter. The PNP transistor is exactly opposite, with its conduction curve where the base is less positive than the emitter, while the collector is also less positive than the emitter.
NPN and PNP are transistor types. The difference in the way the layers of semiconductor material are doped with impurities.
There is no difference they perform the same functions.

Mainly there are two types of transistors. They are BJT (Bipolar Junction Transistors) and FET(Field Effect Transisters). In BJT, there are two types called PNP and NPN. Actually NPN means a BJT transister.
Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.
npn is preferred to pnp since n-doping can be pushed to higher values without damaging silicon lattice. due to this fact, doped regions can be less resistive. difference between npn and pnp is becoming smaller and smaller, tho.
diff. between npn and pnp transristor
Basically the power supply is reversed. The NPN can be used for higher frequencies since electrons can move faster than holes.
Application is asking for an NPN#
The is in refrence to a NPN Prox Switch. These types of electrical sensors are widely used in various types of Manufacturing Facilities. Many of these types of manufactures are well known to the manufacturing community such as diect automation, rockwell automation, keyennce and omron to name a few. NPN prox switches are known for there Neutral to positive sensing characteristics, thus having the output back to the controller a neutral based signal.
