contrinex electrical components Germany contrinex model contrinex price

contrinex electrical components are devices that convert alternating current into direct current, and can be used in power supply units and for detecting radio signals, etc. Rectifiers can be made from vacuum tubes, ignitrons, solid-state silicon semiconductor diodes, mercury arcs, etc. Conversely, a device that converts direct current into alternating current is called an "inverter". In standby UPS, only the battery needs to be charged, without supplying power to the load, so there is only a charger. In double-conversion UPS, this device supplies power to the inverter and also charges the battery, so it is called a rectifier/charger. A rectifier is a rectification device; simply put, it is a device that converts AC to DC. It has two main functions: first, to convert alternating current into direct current, which is filtered and then supplied to the load or to the inverter; second, to provide charging voltage to the battery. Therefore, it also acts as a charger.

contrinex 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 developed based on the principle of this effect. The Doppler effect can be utilized to manufacture ultrasonic proximity switches, microwave proximity switches, etc. When an object approaches, the reflected signal received by the proximity switch undergoes a Doppler frequency shift, thereby allowing identification of 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 typically equipped with anti-theft devices composed of various proximity switches. In measurement technology, such as for length and position; and in control technology, such as for the measurement and control of displacement, speed, and acceleration, a large number of proximity switches are also used.

contrinex electrical component structure

Inductors generally consist of a bobbin, winding, shielding cover, encapsulation material, magnetic core or iron core, etc. 1, Bobbin: The bobbin refers to the support for winding the coil. Most larger fixed inductors or adjustable inductors (such as oscillator coils, choke coils, etc.) involve winding enameled wire (or silk-covered wire) around the bobbin, and then inserting a magnetic core, copper core, or iron core into the inner cavity of the bobbin to increase its inductance. Bobbins are usually made of plastic, bakelite, or ceramic, and can be manufactured in different shapes according to actual needs. Small inductors (such as color-coded inductors) generally do not use a bobbin, but instead wind the enameled wire directly onto the magnetic core. Air-core inductors (also known as formless coils or air coils, mostly used in high-frequency circuits) do not use a magnetic core, bobbin, or shielding cover; 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: The winding refers to a set of coils with specified functions, and 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 (where wires are wound turn by turn adjacent to each other) and spaced-wound (where a certain distance is maintained 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, Shielding Cover: To prevent the magnetic field generated by some inductors during operation from affecting the normal operation of other circuits and components, a metal shielding cover is added (such as the oscillator coil in semiconductor radios). Inductors with shielding covers will experience increased coil losses, resulting in a lower Q value. 13, Encapsulation Material: Some inductors (such as color-coded inductors, color-ring inductors, etc.) are sealed with encapsulation material after winding to enclose the coil and magnetic core. The encapsulation material uses plastic or epoxy resin, etc.

(1) electron tubes can be classified by usage into voltage amplifier tubes, power amplifier tubes, gas-filled tubes, thyratrons, ignitrons, frequency converter tubes, rectifier tubes, detector tubes, tuning indicator tubes (magic eye), voltage regulator tubes, etc. (2) Electron tubes can be classified by the number of electrodes into voltage amplifier tubes, triodes, tetrodes, pentodes, hexodes, heptodes, octodes, nonodes, and composite tubes, etc. Electron tubes with more than three electrodes are also called multi-electrode tubes or multi-grid tubes. (3) Electron tubes can be classified by shape and envelope material into bottle-shaped glass tubes (ST tubes), "acorn" tubes, cylindrical glass tubes (GT tubes), large glass tubes (G style tubes), metal-ceramic tubes, miniature tubes (also called peanut tubes or finger tubes, MT tubes), lighthouse tubes (beacon tubes), sub-miniature tubes (pencil-shaped tubes), and others. (4) Electron tubes can be classified by internal structure into single diodes, diodes, double-diode triodes, dual diodes, single triodes, power pentodes, beam tetrodes, beam pentodes, dual diodes, diode-pentode composite tubes, beam tetrodes, triode-pentode composite tubes, triode-hexode composite tubes, triode-heptode composite tubes, beam power tubes, and other types. (5) Electron tubes can be classified by cathode heating method into directly heated cathode electron tubes (current passes directly through the cathode to achieve thermionic emission state) and indirectly heated cathode electron tubes (the cathode is heated by a filament next to it). (6) Electron tubes can be classified by shielding method into sharp-cutoff shielded electron tubes and remote-cutoff shielded electron tubes. (7) Electron tubes can be classified by cooling method into water-cooled electron tubes, air-cooled electron tubes, and natural convection cooled electron tubes.
