id-technik electrical components Germany id-technik model id-technik price

id-technik electrical components are a commonly used low-current master control device. They utilize the collision of moving parts of production machinery to actuate their contacts, thereby connecting or disconnecting the control circuit to achieve specific control objectives. Typically, such switches are used to limit the position or travel of mechanical motion, causing the moving machinery to automatically stop, reverse, change speed, or perform automatic reciprocating motion according to a specified position or travel. In electrical control systems, the role of position switches is to implement sequence control, positioning control, and detection of position status. They are used to control the travel and limit protection of mechanical equipment. Structure: Composed of an operating head, contact system, and housing. In actual production, limit switches are installed at predetermined positions. When a module mounted on the moving part of the production machinery strikes the limit switch, the contacts of the limit switch actuate, achieving circuit switching. Therefore, a limit switch is an electrical device that switches circuits based on the travel position of moving parts; its operating principle is similar to that of a pushbutton. Limit switches are widely used in various machine tools and hoisting machinery to control their travel and provide terminal limit protection. In elevator control circuits, limit switches are also used to control the speed of opening and closing car doors, automatic door opening/closing limits, and upper/lower limit protection for the car.

id-technik electrical component structure

Inductors are generally composed of a bobbin, winding, shielding cover, encapsulation material, magnetic core, or iron core. 1, Bobbin: The bobbin refers to the support for winding the coil. For some larger fixed inductors or adjustable inductors (such as oscillator coils, choke coils, 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-code inductors) generally do not use a bobbin but directly wind the enameled wire around the magnetic core. Air-core inductors (also known as formless coils or air-core coils, mostly used in high-frequency circuits) do not use magnetic cores, bobbins, or shielding covers; 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 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, and pot shape. 4, Iron Core: Iron core materials mainly include silicon steel sheets and permalloy, 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 of a semiconductor radio). Inductors with shielding covers will increase coil loss, reducing the Q value. 17, Encapsulation Material: Some inductors (such as color-code inductors, color-ring inductors, etc.) are sealed with encapsulation material after winding to enclose the coil and magnetic core. Encapsulation materials include plastic or epoxy resin.

id-technik electrical component function

Low-power resistors are typically composed of carbon film encapsulated in a plastic housing, while high-power resistors are typically wire-wound resistors, made by winding high-resistivity metal wire around a ceramic core. If a resistor's resistance value is close to zero ohms (for example, a large-cross-section wire between two points), the resistor offers no obstruction to current, the circuit parallel to this resistor is short-circuited, and the current becomes infinitely large. If a resistor has infinite or very high resistance, the circuit series-connected with this resistor can be regarded as an open circuit, and the current is zero. Resistors commonly used in industry fall between these two extremes; they have a certain resistance and can pass a certain amount of current, but the current is not as large as in a short circuit. The current-limiting function of a resistor is similar to the effect of a small-diameter pipe limiting water flow between two large-diameter pipes. Resistance, usually abbreviated as R, is a fundamental 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 value corresponding to a current of one ampere generated when one volt of voltage is applied across a conductor. The main function of a resistor is to obstruct the flow of current. In fact, "resistance" refers to a property, while "resistor" in electronic products usually refers to the component itself. Ohm is often abbreviated as Euro. Common units for expressing resistance values also include kilo-ohm (kΩ), mega-ohm (MΩ), and milli-ohm (m Ω).

id-technik electrical component reliability

1, Influence of environment on relay reliability: Relays have the highest mean time between failures when operating under GB and SF conditions. 2, Influence of quality grade on relay reliability: The quality grade of a relay has a significant impact on its reliability performance. 3, Influence of contact form on relay reliability: The contact form of a relay also affects its reliability. The reliability of single-throw relays is higher than that of double-throw relays with the same number of poles, and reliability gradually decreases as the number of poles increases. The mean time between failures for single-pole single-throw relays is higher than that for four-pole double-throw relays. 4, Influence of structural type on relay reliability: There are many types of relay structures, and different types all affect their reliability. 5, Influence of temperature on relay reliability: The operating temperature range of a relay is within a certain limit. As the temperature rises, the mean time between failures of the relay gradually decreases. 6, Influence of operating rate on relay reliability: As the operating rate of the relay increases, the mean time between failures basically shows an exponential downward trend. Therefore, if the designed circuit requires a very high operating rate for the relay, careful inspection of the relay is required during circuit maintenance to replace it in time. 14, Influence of current ratio on relay reliability: The so-called current ratio is the ratio of the relay's working load current to its rated load current. The current ratio has a great impact on the reliability of the relay. Therefore, a load with a larger rated current should be selected during circuit design to reduce the current ratio, ensuring that the reliability of the relay and the entire circuit is not reduced due to fluctuations in working current.
