EMKOPRAHA electrical components Germany EMKOPRAHA model EMKOPRAHA price
EMKOPRAHA electrical components are products whose raw material molecular composition is not changed during factory processing, and can be called components. Components belong to devices that do not require energy. They include: resistors, capacitors, and inductors. Circuit-type components include diodes and resistors; connection-type components include connectors, sockets, connecting cables, and printed circuit boards (PCB). Devices are products whose raw material molecular structure is changed during factory production and processing. Devices are divided into active devices and discrete devices. The main characteristic of active devices is that they consume electrical energy and require an external power supply. Discrete

EMKOPRAHA electrical component principles
The basic working principle of a fiber optic sensor is to guide light from a light source through an optical fiber into a modulator, causing the optical properties of the light (such as intensity, wavelength, frequency, phase, polarization state, etc.) to change after interacting with the parameter to be measured in the modulation region. This results in modulated signal light, and the measurement is completed by utilizing the influence of the measured quantity on the light transmission characteristics. There are two types of fiber optic sensor measurement principles: (1) Physical property fiber optic sensor principle: Physical property fiber optic sensors utilize the sensitivity of the optical fiber to environmental changes to convert input physical quantities into modulated optical signals. Their working principle is based on the optical modulation effect of the fiber, meaning that when external environmental factors such as temperature, pressure, electric fields, or magnetic fields change, the light transmission characteristics, such as phase and light intensity, will change. Therefore, if the changes in light phase and intensity through the fiber can be measured, the changes in the measured physical quantity can be determined. These sensors are also known as sensitive element type or functional fiber optic sensors. The point source beam of a laser is diffused into parallel waves and split into two paths by a beam splitter: one reference path and one measurement path. External parameters (temperature, pressure, vibration, etc.) cause changes in fiber length and optical phase, thereby generating different numbers of interference fringes. Counting their lateral movement allows measurement of temperature or pressure. (7) Structural fiber optic sensor principle: A structural fiber optic sensor is a measurement system composed of a photodetection element (sensitive element), an optical fiber transmission loop, and a measurement circuit. In this case, the optical fiber serves only as a medium for light propagation, so it is also called a light-transmitting or non-functional fiber optic sensor.
EMKOPRAHA electrical component classification
A self-inductor generates a magnetic field around the coil when current flows through it. When the current in the coil changes, the surrounding magnetic field changes correspondingly. This changing magnetic field induces an electromotive force (induced EMF) in the coil itself (EMF is used to represent the terminal voltage of an ideal power source in an active component), which is called self-inductance. An electronic component made by winding wire with a certain number of turns, capable of producing a certain amount of self-inductance or mutual inductance, is commonly called an inductor coil. To increase inductance, improve the quality factor, and reduce volume, a core made of ferromagnetic material, such as an iron core or magnetic core, is often added. Basic parameters of an inductor include inductance, quality factor, inherent capacitance, stability, rated current, and operating frequency. An inductor composed of a single coil is called a self-inductor, and its self-inductance is also referred to as the self-inductance coefficient. A mutual inductor occurs when two inductor coils are close to each other; the magnetic field change in one coil affects the other coil. This effect is called mutual inductance. The magnitude of mutual inductance depends on the self-inductance of the coils and the degree of coupling between them. Components manufactured using this principle are called mutual inductors.
