IFMELECTRONIC electrical components are conductive devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to another. An electronic connector is an electromechanical system that provides a separable interface for connecting two subsystems. Simply put, components used to complete electrical connections between circuits or electronic devices are called connectors, serving as a bridge between them. Electronic connectors are also commonly referred to as circuit connectors or electrical connectors, bridging two conductors in a circuit to allow current or signals to flow from one conductor to another. They are widely used in various electrical circuits to connect or disconnect current or signals. This connection may be temporary and convenient for plugging and unplugging, or it may be a permanent joint between electrical equipment or wires. Electronic connectors are devices for transmitting electronic signals (analog or digital), providing a separable interface to connect two subsystems, and are components used to complete electrical connections between circuits or electronic machines. Examples include power plugs/sockets, IC sockets, and telephone line plugs. They are widely used in the electronics industry. An electronic connector is an electromechanical system that provides a separable interface for connecting two subsystems. Simply put, components used to complete electrical connections between circuits or electronic devices are called connectors, serving as a bridge between them. Electronics can serve as electrical/electronic transmission and connection components between circuits, components, and systems, enabling stable and reliable flow of power, signals, and current, while facilitating product assembly, maintenance, and replacement.

IFMELECTRONIC electrical component classification

1. By application: pressure-sensitive and force-sensitive sensors, position sensors, level sensors, energy consumption sensors, speed sensors, acceleration sensors, radiation sensors, thermal sensors. 2. By principle: vibration sensors, humidity-sensitive sensors, magnetic-sensitive sensors, gas-sensitive sensors, vacuum degree sensors, biosensors, etc. 3. By output signal: (1) Analog sensors convert the measured non-electrical quantity into an analog electrical signal. (2) Digital sensors: convert the measured non-electrical quantity into a digital output signal (including direct and indirect conversion). (3) Pseudo-digital sensors: convert the measured signal quantity into a frequency signal or short-period signal output (including direct or indirect conversion). (4) Switch sensors: when a measured signal reaches a specific threshold, the sensor outputs a set low-level or high-level signal accordingly. 4. By manufacturing process: Integrated sensors are manufactured using standard production processes for silicon-based semiconductor integrated circuits. Usually, part of the circuit for initial processing of the measured signal is also integrated on the same chip. Thin-film sensors are formed by depositing thin films of corresponding sensitive materials on a dielectric substrate (base plate). When using hybrid processes, part of the circuit can also be fabricated on this substrate. Thick-film sensors are made by coating ceramic substrates, usually made of alumina, with slurries of corresponding materials, followed by heat treatment to form the thick film. Ceramic sensors are produced using standard ceramic processes or their variants (sol-gel, etc.). After appropriate preparatory operations, the formed elements are sintered at high temperatures. There are many common characteristics between thick-film and ceramic sensor processes; in some respects, thick-film technology can be considered a variant of ceramic technology. Each process technology has its own advantages and disadvantages. Due to lower capital investment required for research, development, and production, as well as the high stability of sensor parameters, it is more reasonable to use ceramic and thick-film sensors. 5. By measurement purpose: Physical sensors are made using characteristics where certain physical properties of the measured substance undergo significant changes. Chemical sensors are made using sensitive elements that can convert chemical quantities such as composition and concentration of chemical substances into electrical quantities. Biological sensors are made using various biological or biomaterial characteristics to detect and identify chemical components in living organisms. 6. By structure: (1) Basic sensors are the most fundamental single transduction devices. (2) Combined sensors are sensors composed of different single transduction devices. (3) Application-specific sensors are sensors composed of basic or combined sensors combined with other mechanisms. 10. By mode of action: Sensors can be divided into active and passive types based on their mode of action. Active sensors include acting-type and reaction-type. Such sensors can emit a certain detection signal to the measured object, detect changes produced by the detection signal in the measured object, or form a signal by producing a certain effect in the measured object. Those detecting changes in the detection signal are called acting-type, while those detecting responses to form signals are called reaction-type. Radar and radio frequency detectors are examples of acting-type, while photoacoustic effect analysis devices and laser analyzers are examples of reaction-type. Passive sensors only receive signals generated by the measured object itself, such as infrared radiation thermometers and infrared imaging devices.

IFMELECTRONIC electrical component principles

A photodiode is a semiconductor device that converts light signals into electrical signals. Its core part is also a PN junction. Compared with ordinary diodes, the structural difference is that to facilitate the reception of incident light, the PN junction area is made as large as possible, the electrode area is made as small as possible, and the junction depth of the PN junction is very shallow, generally less than 1 micrometers. Photodiodes operate under reverse bias. Without illumination, the reverse current is very small, known as dark current. When illuminated, photons carrying energy enter the PN junction, transferring energy to bound electrons in covalent bonds, causing some electrons to break free from covalent bonds, thereby generating electron-hole pairs, known as photogenerated carriers. Under the influence of reverse voltage, they participate in drift motion, significantly increasing the reverse current; the greater the light intensity, the larger the reverse current. This characteristic is called "photoconductivity." The current generated by a photodiode under normal illumination is called photocurrent. If a load is connected in the external circuit, the load receives an electrical signal, which changes correspondingly with changes in light. Photodiodes are widely used photosensitive devices in electronic circuits. Like ordinary diodes, photodiodes have a PN junction. The difference is that the photodiode housing has a transparent window to receive light irradiation, achieving photoelectric conversion. In circuit diagrams, the text symbol is generally VD.
