The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

Application characteristics help specifiers choose the best discrete sensor type. Industrial automation systems depend on sensors to detect what is going on with machinery and products for effective ...

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 described ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

Transistor instead of reed: As the first instrument of its kind, WIKA has launched a float switch with a PNP/NPN output signal. The model GLS-1000 detects the level of liquids with an accuracy of ≤ 1 ...
