Automation Electronics Control Engineering: 3-wire proximity switch PNP, NPN's the difference? 1, PNP and NPN sensors generally have three pin-out, that is power line VCC, GND, OUT signal output line 1, NPN type NPN is triggered when a signal, the signal output line OUT and GND connections, equivalent to the output OUT low. 2, PNP type PNP is ...
difference between NPN/PNP Sensors - Control.com - Forum for Automation Professionals An NPN or sinking output accepts voltage and sinks it to ground to complete the circuit. A PNP or sourcing output sources voltage and the external circuit sinks it to ground to complete the circuit. A sourcing circuit would be drawn as voltage->switch->lo
Pnp Vs. Npn Transistor | eHow - eHow | How to - Discover the expert in you! Transistors are semiconductor devices that have at least three terminals. A small current or voltage through the middle terminal is used to control the current flow through the others. They function as electronic valves. Their primary uses are as switches
NPN vs. PNP Transistors - YouTube Comparison between the two most common types of transistors, and when to use which.
The Difference Between NPN & PNP Transistors | eHow Bipolar junction transistors are among the most commonly used components found in electronic circuits. Bipolar junction transistors -- or BJTs for short -- come in two varieties: the PNP transistor and the NPN transistor. These transistors operate similar

Bipolar junction transistor - Wikipedia, the free encyclopedia A BJT consists of three differently doped semiconductor regions, the emitter region, the base region and the collector region. These regions are, respectively, p type, n type and p type in a PNP transistor, and n type, p type and n type in an NPN transist
