Pnp Sensor Wikipedia

Beim pnp-Transistor ist die Reihenfolge der Schichten p-n-p, d. h., die beiden Dioden zwischen Basis und Emitter sowie zwischen Basis und Kollektor haben jeweils die entgegengesetzte Polung gegenüber dem npn-Typ. Im Schaltzeichen drückt man diesen Unterschied aus, indem man den Richtungspfeil der Basis-Emitter-Diode umdreht.

The difference between NPN and PNP transistors is in their internal structure and the direction the electrical current flows. Most of the time, either type of transistor may be used. NPN and PNP are both bipolar junction transistors, used to amplify currents. NPN stands for Negative-Positive-Negative and PNP stands for Positive-Negative-Positive.

A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity
