exide electrical components, German exide models, exide prices

exide electrical components refer to electronic components that can open a circuit, interrupt current flow, or direct it to other circuits. The most common switches are manually operated electromechanical devices with one or more electrical contacts. "Closed" contacts indicate conduction, allowing current to flow; "open" switches indicate non-conduction, forming an open circuit and preventing current flow. The simplest switch consists of two metal pieces called "contacts"; when they touch, current forms a loop, and when they do not, the circuit is open. When selecting contact metals, their resistance to corrosion must be considered, as most metals form insulating oxides after oxidation, preventing normal contact operation. Selection also requires considering factors such as electrical conductivity, hardness, mechanical strength, cost, and toxicity. Contacts are sometimes plated with corrosion-resistant metals, typically on the contact surface, to avoid performance degradation due to oxides. Non-metallic conductive materials, such as conductive plastics, are sometimes used for contact surfaces. In addition to contacts, switches contain movable parts that make or break the connection. Based on the movable part, switches are classified as toggle switches, push-button switches, rocker switches, etc., and the movable part can also be other types of mechanical linkages.

exide electrical component characteristics

The static characteristics of a sensor refer to the relationship between its output and input for static input signals. Since input and output are independent of time in this state, their relationship—the sensor's static characteristics—can be described by an algebraic equation without time variables, or by a characteristic curve plotting input on the horizontal axis and corresponding output on the vertical axis. Key parameters characterizing static characteristics include: linearity, sensitivity, hysteresis, repeatability, and drift. (1) Linearity: Refers to the degree to which the actual relationship curve between sensor output and input deviates from the fitted straight line. It is defined as the ratio of the maximum deviation between the actual characteristic curve and the fitted line over the full scale range to the full-scale output value. (2) Sensitivity: Sensitivity is an important indicator of a sensor's static characteristics. It is defined as the ratio of the increment in output to the corresponding increment in input that causes it. S is used to denote sensitivity. (3) Hysteresis: Hysteresis is the phenomenon where the input-output characteristic curves do not coincide when the input changes from small to large (forward stroke) and from large to small (reverse stroke). For the same input signal magnitude, the output signals for forward and reverse strokes differ; this difference is called the hysteresis error. (4) Repeatability: Repeatability refers to the degree of inconsistency in characteristic curves obtained when the sensor input undergoes multiple consecutive full-scale changes in the same direction. (5) Drift: Sensor drift refers to the change in sensor output over time while the input remains constant. Drift arises from two main sources: the sensor's own structural parameters and the surrounding environment (e.g., temperature, humidity). (6) Resolution: When the sensor input increases slowly from a non-zero value, the minimum input increment required to produce an observable change in output is called the sensor's resolution. (7) Threshold: When the sensor input increases slowly from zero, the input value at which an observable change in output occurs is called the sensor's threshold voltage.

exide electrical component types

There are many types of loudspeakers. Based on transduction principles, they are classified as electrodynamic (moving-coil), electrostatic (capacitive), electromagnetic (reed), piezoelectric (crystal), etc.; the latter two are mostly used in rural wired broadcasting networks. By frequency range, they are classified as low-frequency, mid-frequency, and high-frequency speakers, often used as composite speakers in speaker cabinets. By transduction mechanism and structure, they include moving-coil (electrodynamic), capacitive (electrostatic), piezoelectric (crystal or ceramic), electromagnetic (spring-loaded), ionophone, and pneumatic speakers. Electrodynamic speakers are widely used due to advantages such as good electro-acoustic performance, robust structure, and low cost. By sound radiation material, they are classified as cone, horn, and diaphragm types. By cone shape, they are circular, oval, dual-cone, and rubber surround. By operating frequency, they are bass, midrange, and treble; some are further specialized for recorders, televisions, general use, and hi-fi. By voice coil impedance, they are low-impedance and high-impedance. By effect, they are direct-radiating and ambient sound types. Speakers are divided into built-in and external speakers; external speakers are generally referred to as speaker boxes. Built-in speakers mean that the MP4 player has integrated speakers, allowing users to listen to sound from the MP4 player not only through the headphone jack but also through the built-in speakers. MP11 players with built-in speakers can operate without external speakers and avoid the inconvenience of wearing headphones for extended periods.

Sensitivity refers to the ratio of the change in output to the change in input of a sensor under steady-state operating conditions. It is the slope of the output-input characteristic curve. If the sensor exhibits a linear relationship between output and input, then sensitivity S is a constant. Otherwise, it varies with changes in input. The dimension of sensitivity is the ratio of the dimensions of output to input. When the dimensions of output and input are the same, sensitivity can be understood as the amplification factor. Higher sensitivity yields higher measurement precision. However, the higher the sensitivity, the narrower the measurement range and often the poorer the stability.
