Below you can see the standard wiring diagram of a 3-wire PNP sensor. For a quick test, I set up a breadboard mock-up and powered it from a regulated 5VDC breadboard power supply module. My first ...

Matching a sensor interface with a programmable logic converter or controller hardware that can accept only one type of input—npn or pnp—can be difficult. The last-stage modification circuit ...

Figure 13: In this image we have an LTC2991 and two 2N3906 PNP temperature sensors. ... To get a sense of magnitude, a simulation of the above circuit with an input of 5V to represent a gate drive ...

Sourcing power means the sensor output supplies a positive voltage when the sensor turns on. This is called a pnp output. The name comes from the pnp output transistors used to control the power.
