Electronic Sensors and Components

Front

What is a transistor?

Back

A semiconductor device used to amplify or switch electronic signals.

Front

What is an NPN transistor?

Back

A type of transistor where current flows from collector to emitter when the base is energized.

Front

What is a PNP transistor?

Back

A type of transistor where current flows from emitter to collector when the base is energized.

Front

What is the output of a sensor or transistor?

Back

The signal or response produced when an object is detected.

Front

What is a sensor?

Back

A device that detects physical properties (like presence, distance, or material) and converts them into an electrical signal.

Front

What is electronic circuitry in a sensor?

Back

The internal components of a sensor that process input signals to generate an output.

Front

What is a power supply?

Back

The source of electrical energy for a sensor or circuit.

Front

What is a switch?

Back

A device (mechanical or electronic) that opens or closes a circuit; sensors often act as switches electronically.

Front

What is an inductive proximity sensor?

Back

A sensor that detects metallic objects without contact by using electromagnetic induction.

Front

What is induction?

Back

The principle where a changing magnetic field generates a current in a metallic object.
