AnaPico electrical components Germany AnaPico model AnaPico price

AnaPico electrical components are switches controlled by electromagnets, that is, a combination of an electromagnet and a switch. When the electromagnet coil is energized, it generates electromagnetic attraction, causing the movable iron core to push or pull the switch contacts to close, thereby connecting the controlled circuit. Electromagnetic switches are widely used in various industries, most commonly as contactors in the industrial sector. An electromagnetic switch is the control switch on a starter motor and is one of the three major components of a starter motor (DC motor, transmission engagement mechanism, electromagnetic switch). Its working principle is that when the coil is energized, it generates electromagnetic attraction, causing the movable iron core to move. This on one hand pulls the transmission engagement mechanism to move the starter pinion forward to engage with the engine flywheel ring gear, and on the other hand pushes the switch contacts to connect, allowing the DC motor to be energized and operate, thereby driving the engine to start.

AnaPico electrical component classification

Inductor coils commonly used in circuits can be roughly classified into several types: Classification by inductance form: fixed inductors, variable inductors. Classification by magnetic core material: air-core coils, ferrite coils, iron-core coils, copper-core coils. Classification by operating nature: antenna coils, oscillator coils, choke coils, trap coils, deflection coils. Classification by winding structure: single-layer coils, multi-layer coils, honeycomb coils, close-wound coils, spaced-wound coils, self-supporting coils, honeycomb coils, random-wound coils.

AnaPico electrical component principle

A light-emitting diode, like a standard diode, is composed of a PN junction and also exhibits unidirectional conductivity. When a forward voltage is applied to the light-emitting diode, holes injected from the P region into the N region and electrons injected from the N region into the P region recombine with electrons in the N region and holes in the P region, respectively, within a few micrometers near the PN junction, producing spontaneous radiation fluorescence. The energy states of electrons and holes differ in different semiconductor materials. The amount of energy released during electron-hole recombination varies; the greater the energy released, the shorter the wavelength of the emitted light. Commonly used diodes emit red, green, or yellow light. The reverse breakdown voltage of a light-emitting diode is greater than 13 volts. Its forward volt-ampere characteristic curve is very steep, so a current-limiting resistor must be connected in series during use to control the current through the diode. The core part of a light-emitting diode is a chip composed of P-type semiconductor and N-type semiconductor. Between the P-type semiconductor and the N-type semiconductor there is a transition layer called the PN junction. In the PN junction of certain semiconductor materials, when injected minority carriers recombine with majority carriers, the excess energy is released in the form of light, thereby directly converting electrical energy into light energy. When a reverse voltage is applied to the PN junction, minority carriers are difficult to inject, so no light is emitted. When it is in a forward operating state (i.e., a forward voltage is applied across its terminals), current flows from the LED anode to the cathode, and the semiconductor crystal emits light of different colors from ultraviolet to infrared. The intensity of the light is related to the current.

Fiber optic connectors can be divided into common single-mode and multi-mode connectors for silica-based optical fibers based on the transmission medium, as well as other fiber optic connectors using plastics etc. as the transmission medium. Based on the connector structure, they can be divided into: FC, SC, ST, LC, D14, DIN, MU, MT, and various other forms. Among them, ST connectors are typically used at the cabling equipment end, such as fiber patch panels and fiber modules; while SC and MT connectors are typically used at the network equipment end. Based on the fiber end-face shape, they are classified into FC, PC (including SPC or UPC), and APC; based on the number of fiber cores, they are divided into single-core and multi-core (such as MT-RJ). Fiber optic connectors are widely used and come in many varieties. In practical applications, we generally distinguish them based on the different structures of the fiber optic connectors.
