Exor electrical components German Exor models Exor prices

Exor electrical components are constituent parts of electronic components and small electrical machines and instruments. They often consist of several parts and are interchangeable within similar products. The term commonly refers to certain parts in the electrical appliance, radio, and instrumentation industries. In practice, electronic components is a collective term for both components and devices.

Types of Exor electrical components

(1) Electron tubes can be classified into voltage amplifier tubes, power amplifier tubes, gas-filled tubes, thyratrons, ignitrons, frequency converter tubes, rectifier tubes, detector tubes, tuning indicator tubes (magic eye), voltage regulator tubes, etc., according to their different applications. (2) Electron tubes can be classified into voltage amplifier tubes, triodes, tetrodes, pentodes, hexodes, heptodes, octodes, nonodes, and compound tubes, etc., according to the different number of electrodes. Electron tubes with more than three electrodes are also called multi-electrode tubes or multi-grid tubes. (3) Electron tubes can be classified into various types according to their shape and envelope material, such as bottle-shaped glass tubes (ST tubes), "acorn" tubes, cylindrical glass tubes (GT tubes), large glass tubes (G type tubes), metal-ceramic tubes, miniature tubes (also called peanut tubes or finger-shaped tubes, MT tubes), lighthouse tubes (beacon tubes), and subminiature tubes (pencil tubes). (4) According to internal structure, electron tubes can be classified into single diodes, diodes, double-diode triodes, double diodes, single triodes, power pentodes, beam tetrodes, beam pentodes, dual diodes, diode-pentode compound tubes, beam tetrodes, triode-pentode compound tubes, triode-hexode compound tubes, triode-heptode compound tubes, and beam power tubes, among other types. (5) Electron tubes can be classified into directly heated cathode electron tubes (current passes directly through the cathode to bring it to thermionic emission state) and indirectly heated cathode electron tubes (the cathode is heated by a filament adjacent to the cathode), according to the cathode heating method. (6) Electron tubes can be classified into sharp-cutoff shielded electron tubes and remote-cutoff shielded electron tubes, according to the shielding method. (7) Electron tubes can be classified into water-cooled electron tubes, air-cooled electron tubes, and natural convection-cooled electron tubes, according to the cooling method.

Exor electrical component performance

The main performance indicators of loudspeakers include sensitivity, frequency response, rated power, rated impedance, directivity, and distortion. (1) Rated power: Loudspeaker power is categorized into nominal power and maximum power. Nominal power, also called rated power or non-distortion power, refers to the maximum input power allowed within the rated non-distortion range. The power value marked on the loudspeaker's label or technical manual is this rated power. Maximum power refers to the peak power the loudspeaker can withstand for an instant. (2) Rated impedance: Loudspeaker impedance is generally frequency-dependent. (3) Frequency response: When audio signals of the same voltage but different frequencies are applied to a loudspeaker, the resulting sound pressure varies. Typically, sound pressure is higher at mid-frequencies and lower at low and high frequencies. The frequency range of high and low tones where the sound pressure drops to a specific value relative to the mid-frequency level is called the loudspeaker's frequency response characteristic. (4) Distortion: Distortion is the phenomenon where a loudspeaker fails to accurately reproduce the original sound. There are two types: frequency distortion and nonlinear distortion. Frequency distortion occurs when some frequency signals are amplified more strongly than others, disrupting the original balance of loudness across frequencies and altering the timbre. Nonlinear distortion arises because the vibration of the loudspeaker's moving system does not fully match the signal fluctuations, introducing new frequency components into the output sound. (5) Directivity characteristic: This characterizes the distribution of sound pressure radiated by the loudspeaker in various spatial directions. Higher frequencies result in narrower directivity, and larger cones result in stronger directivity.

Exor electrical component applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. Based on the nature of the output quantity, photoelectric sensors can be divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously varying photocurrent. These can measure physical quantities such as light intensity, object temperature, light transmittance, displacement, and surface condition. Examples include illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters, turbidimeters, photoelectric fire alarms, and automatic inspection devices and instruments for checking the diameter, length, ovality, and surface roughness of machined parts, all of which use photoelectric elements as sensitive components. Semiconductor photoelectric elements are widely used not only in civil industrial fields but also hold significant importance in military applications. For example, lead sulfide photoresistors can be used to make infrared night vision devices, infrared cameras, and infrared navigation systems; (3) Devices that convert the measured quantity into a continuously varying photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "present" or "absent" electrical signals when exposed to light or no light. Photoelectric elements serve as switching photoelectric conversion components. Examples include photoelectric inputs for computers, switching temperature control devices, and digital photoelectric tachometers for speed measurement.
