Industrial sensors are critical components in modern automation systems, providing real-time data about various parameters like temperature, pressure, flow, and proximity. Their operation generally relies on physical or chemical phenomena converting into an electrical signal. Common sensor types include resistive, capacitive, inductive, piezoelectric, and optical sensors, each utilizing different principles of measurement. Understanding PNP and NPN refers to the output configuration – essentially the type of circuit used to indicate a detected event. A PNP sensor outputs a high signal when an object is present, requiring a common positive voltage; conversely, an NPN sensor provides a high signal when an object is present, using a common negative voltage. Selection between PNP and NPN depends on the control circuitry and application requirements.
