ELB EX-GERAETE 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, acting 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) and provide a separable interface to connect two subsystems, serving as components to complete electrical connections between circuits or electronic machines. Examples include power plugs/sockets, IC pin 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, acting 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.

ELB EX-GERAETE electrical component functions

Low-power resistors are typically composed of a carbon film encapsulated in a plastic housing, while high-power resistors are typically wire-wound resistors, made by winding metal wire with high resistivity around a ceramic core. If the resistance of a resistor is close to zero ohms (for example, a large-cross-section conductor between two points), then the resistor offers no obstruction to current, the circuit with this resistor connected in parallel is short-circuited, and the current is infinitely large. If a resistor has infinite or very high resistance, the circuit with this resistor connected in series can be regarded as an open circuit, and the current is zero. Resistors commonly used in industry fall between these two extremes; they have a certain resistance, allow a certain current to pass, but the current is not as large as in a short circuit. The current-limiting effect of a resistor is similar to the effect of a small-diameter pipe connected between two large-diameter pipes restricting water flow. Resistance, usually abbreviated as R, is a fundamental property of a conductor, related to the conductor's dimensions, material, and temperature. Ohm's law states that I=U/R, so R=U/I, The basic unit of resistance is the ohm, Denoted by the Greek letter "Ω", It is defined as follows: when a voltage of one volt is applied across a conductor, the resistance corresponding to a current of one ampere. The primary function of resistance is to impede the flow of electric current. In fact, "resistance" refers to a property, whereas the term "resistor" commonly used in electronic products refers to a component known as a resistor. The ohm is often abbreviated as "ohm". Common units for expressing resistance values also include kilo-ohm (kΩ), mega-ohm (MΩ), milli-ohm (m Ω).

ELB EX-GERAETE electrical component characteristics

The main parameters characterizing resistor properties include nominal resistance and its tolerance, rated power, load characteristics, and temperature coefficient of resistance. Load characteristics: When the ambient operating temperature is below tR, the resistor must not exceed its rated power. When exceeding tR, the load power must be derated. Each type of resistor has specified load characteristics. Additionally, the allowable load decreases under low atmospheric pressure. Under pulse loads, the average pulse power is much lower than the rated power, and separate specifications usually apply. Within the specified ambient temperature range, the average relative change in resistance per 7℃ change in temperature is expressed in ppm/℃. In addition to the above parameters, other technical indicators include nonlinearity (the degree to which the current-voltage characteristic deviates from a linear relationship), voltage coefficient (the relative rate of change in resistance per volt change in applied voltage), current noise (the ratio of the effective value of the noise potential generated by current flow within the resistor body to the test voltage, expressed by the current noise index), high-frequency characteristics (the curve showing the decrease in resistance with increasing operating frequency due to the influence of distributed capacitance and inductance within the resistor body), and long-term stability (the process of irreversible changes in resistance caused by environmental conditions during long-term use or storage).

ELB EX-GERAETE electrical component characteristics

The static characteristics of a sensor refer to the relationship between the output and input quantities for static input signals. Since the input and output quantities are independent of time in this case, their relationship, i.e., the static characteristics of the sensor, can be described by an algebraic equation without time variables, or by a characteristic curve plotted with the input quantity as the abscissa and the corresponding output quantity as the ordinate. The main parameters characterizing the static characteristics of a sensor include linearity, sensitivity, hysteresis, repeatability, and drift. (1) Linearity: Refers to the degree to which the actual relationship curve between the sensor's 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 straight 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 quantity to the corresponding increment in input quantity that causes it. S is used to represent sensitivity. (3) Hysteresis: Hysteresis is the phenomenon where the input-output characteristic curves do not coincide when the input quantity changes from small to large (forward stroke) and from large to small (reverse stroke). For the same magnitude of input signal, the output signals for the forward and reverse strokes are not equal; this difference is called the hysteresis error. (4) Repeatability: Repeatability refers to the degree of inconsistency in the characteristic curves obtained when the sensor's input quantity undergoes continuous multiple full-scale changes in the same direction. (5) Drift: Sensor drift refers to the phenomenon where the sensor's output changes over time while the input remains constant. There are two main causes of drift: one is the sensor's own structural parameters, and the other is the surrounding environment (such as temperature, humidity, etc.). (6) Resolution: When the sensor's input slowly increases from a non-zero value, an observable change in output occurs after exceeding a certain increment. This input increment is called the sensor's resolution, i.e., the minimum input increment. (7) Threshold: When the sensor's input slowly increases from zero, an observable change in output occurs after reaching a certain value. This input value is called the sensor's threshold voltage.
