SIBA electrical components Germany SIBA model SIBA price

SIBA electrical components are energy conversion devices that convert DC electrical energy into AC electrical energy with a specific frequency; the circuit they form is called an oscillating circuit. An oscillator is simply a frequency source, generally used in phase-locked loops. In detail, it is a device that can convert DC electrical energy into AC electrical energy on its own without external signal excitation. It is generally divided into two types: positive feedback and negative resistance. The term "oscillation" implies alternating current; an oscillator includes the process and function of transitioning from non-oscillating to oscillating. Such a device capable of completing the conversion from DC electrical energy to AC electrical energy can be called an "oscillator". Oscillators can be mainly divided into two types: harmonic oscillators and relaxation oscillators. They are electronic components used to generate repetitive electronic signals (usually sine waves or square waves). The circuit they form is called an oscillating circuit. It is an electronic circuit or device that can convert DC electricity into AC electrical signal output with a specific frequency. There are many types; classified by oscillation excitation method, they include self-excited oscillators and externally excited oscillators; classified by circuit structure, they include RC oscillators, LC oscillators, crystal oscillators, tuning fork oscillators, etc.; classified by output waveform, they include sine wave, square wave, sawtooth wave oscillators, etc. They are widely used in the electronics industry, medical care, scientific research, and other aspects.

SIBA electrical component functions

When the distance between the observer or system and the wave source changes, the frequency of the approaching waves shifts; this phenomenon is called the Doppler effect. Sonar and radar are made based on the principle of this effect. The Doppler effect can be used to make ultrasonic proximity switches, microwave proximity switches, etc. When an object moves closer, the reflected signal received by the proximity switch produces a Doppler frequency shift, thereby identifying whether an object is approaching. Proximity switches are widely used in aviation, aerospace technology, and industrial production. In daily life, they are applied in automatic doors in hotels, restaurants, and garages, as well as in automatic hot air blowers. For security and anti-theft purposes, important locations such as archives, accounting departments, financial institutions, museums, and vaults are usually equipped with anti-theft devices composed of various proximity switches. In measurement technology, such as length and position measurement; in control technology, such as displacement, speed, and acceleration measurement and control, a large number of proximity switches are also used.

SIBA electrical component structure

Inductors are generally composed of a bobbin, winding, shield, encapsulation material, magnetic core or iron core, etc. 1, Bobbin The bobbin refers to the support for winding the coil. For some larger fixed inductors or adjustable inductors (such as oscillation coils, chokes, etc.), enameled wire (or silk-covered wire) is mostly wound around the bobbin, and then a magnetic core, copper core, or iron core is inserted into the inner cavity of the bobbin to increase its inductance. Bobbins are usually made of plastic, bakelite, or ceramic, and can be made into different shapes according to actual needs. Small inductors (such as color-coded inductors) generally do not use bobbins, but directly wind enameled wire around the magnetic core. Air-core inductors (also known as former-less coils or air-core coils, mostly used in high-frequency circuits) do not use magnetic cores, bobbins, or shields; instead, they are wound on a mold first, then the mold is removed, and a certain distance is maintained between the turns of the coil. 2, Winding A winding refers to a set of coils with specified functions; it is the basic component of an inductor. Windings are divided into single-layer and multi-layer types. Single-layer windings have two forms: close-wound (wires are wound circle by circle adjacent to each other) and spaced-wound (a certain distance is kept between each turn of wire during winding); multi-layer windings include layered flat winding, random winding, honeycomb winding, and other methods. 3, Magnetic Core and Magnetic Rod Magnetic cores and magnetic rods are generally made of materials such as nickel-zinc ferrite or manganese-zinc ferrite; they come in various shapes such as "I" shape, cylindrical, cap-shaped, "E" shape, pot shape, etc. 4, Iron Core Iron core materials mainly include silicon steel sheets, permalloy, etc., and their shape is mostly "E" type. 5, Shield To prevent the magnetic field generated by some inductors during operation from affecting the normal operation of other circuits and components, a metal shield is added (such as the oscillation coil of a semiconductor radio). Inductors with shields will increase coil loss, reducing the Q value. 9, Encapsulation Material After some inductors (such as color-coded inductors, color-ring inductors, etc.) are wound, the coil and magnetic core are sealed with encapsulation material. The encapsulation material uses plastic or epoxy resin, etc.

A relay is an automatic switching component with isolation functions, widely used in remote control, telemetry, communications, automatic control, mechatronics, and power electronic equipment, and is one of the most important control components. Relays generally have a sensing mechanism (input part) that can reflect certain input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); an actuating mechanism (output part) that can realize "on" and "off" control of the controlled circuit; and between the input and output parts of the relay, there is an intermediate mechanism (drive part) for coupling isolation of the input quantity, functional processing, and driving the output part. As a control component, relays have the following functions in summary: (1) Expand control range: For example, when the control signal of a multi-contact relay reaches a certain value, it can simultaneously switch, disconnect, and connect multiple circuits according to different forms of contact groups. (2) Amplification: For example, sensitive relays and intermediate relays can control high-power circuits with a very small control quantity. (3) Signal integration: For example, when multiple control signals are input into a multi-winding relay in a prescribed form, comparison and integration achieve the predetermined control effect. (4) Automatic, remote control, monitoring: For example, relays on automatic devices, together with other electrical appliances, can form program control circuits to achieve automated operation.
