Mecatraction electrical components Germany Mecatraction model Mecatraction price

Mecatraction electrical components refer to an electrical device that disconnects the circuit by melting the fusible element with the heat generated by itself when the current exceeds the specified value. A fuse is a current protection device made based on the principle that when the current exceeds the specified value for a period of time, the heat generated by itself melts the fusible element, thereby disconnecting the circuit. Fuses are widely used in high and low voltage distribution systems, control systems, and electrical equipment as short-circuit and overcurrent protectors, and are one of the most commonly used protective devices. It is an electrical device that uses a metal conductor as the fusible element connected in series in the circuit. When overload or short-circuit current passes through the fusible element, it melts due to its own heating, thereby breaking the circuit. The fuse has a simple structure and is easy to use. It is widely used in power systems, various electrical equipment, and household appliances as a protective device.

Mecatraction electrical component function

Low-power resistors are usually composed of carbon film encapsulated in a plastic housing, while high-power resistors are usually wirewound 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 wire between two points), the resistor has no hindrance to the current, the loop with this resistor in parallel is short-circuited, and the current is infinitely large. If a resistor has infinite or very large resistance, the loop with this resistor in series can be regarded as an open circuit, and the current is zero. Resistors commonly used in industry lie between these two extremes; they have a certain resistance and can pass a certain current, 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 limiting water flow. Resistance, usually abbreviated as R, is a basic property of a conductor, related to the conductor's size, material, and temperature. Ohm's law states that I=U/R, so R=U/I. The basic unit of resistance is the ohm, represented by the Greek letter "Ω". It is defined as the resistance corresponding to a current of one ampere generated when a voltage of one volt is applied across a conductor. The main function of resistance is to hinder the flow of current. In fact, "resistance" refers to a property, while the term "resistor" in electronic products usually refers to the component known as a resistor. Ohm is often abbreviated as Ohm. Common units for expressing resistance values also include kiloohm (kΩ), megaohm (MΩ), and milliohm (m Ω).

Mecatraction electrical component characteristics

Sensitivity refers to the ratio of the change in output quantity to the change in input quantity of a sensor under steady-state working conditions. It is the slope of the output-input characteristic curve. If there is a linear relationship between the output and input of the sensor, then the sensitivity S is a constant. Otherwise, it will vary with changes in the input quantity. The dimension of sensitivity is the ratio of the dimensions of the output and input quantities. When the dimensions of the output and input quantities of the sensor are the same, sensitivity can be understood as the amplification factor. Increasing sensitivity can achieve higher measurement accuracy. However, the higher the sensitivity, the narrower the measurement range, and the stability is often poorer.
