omnitronic electrical components Germany omnitronic model omnitronic price

omnitronic electrical components are a common type of low-current master control appliance. They utilize the collision of moving parts of production machinery to actuate their contacts, thereby making or breaking control circuits 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 at 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 provide limit protection for mechanical equipment. Construction: 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 appliance 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, provide automatic door opening/closing limit protection, and provide upper and lower limit protection for the car.

omnitronic electrical component applications

Semiconductor diodes are used in almost all electronic circuits. The use of semiconductor diodes in circuits can protect the circuit and extend its service life. The development of semiconductor diodes has optimized integrated circuits and played a positive role in various fields. Diodes serve many functions in integrated circuits, maintaining their normal operation. The following briefly introduces the roles of diodes in the following four types of circuits. (1) Switching circuits: In digital and integrated circuits, the unidirectional conductivity of diodes is utilized to make or break circuits. This technology is widely applied. Switching diodes can effectively protect circuits from damage due to short circuits and other issues, and can also realize the functions of traditional switches. Another characteristic of switching diodes is their fast switching speed, which is incomparable to traditional switches. (2) Limiter circuits: In electronic circuits, limiter circuits are commonly used to process various signals. They are used to selectively transmit part of the signal within a preset voltage level range. Most diodes can be used as limiters, but sometimes specialized limiter diodes are required, such as when protecting instruments. (3) Voltage regulator circuits: Zener diodes are typically used in voltage regulator circuits. They are junction-type silicon semiconductor diodes manufactured using special processes. These special diodes have a high impurity concentration and high charge density in the space charge region, making it easy to form a strong electric field. When the reverse voltage across the Zener diode reaches a certain value, the reverse current increases sharply, causing reverse breakdown. (11) Varactor circuits: Varactor diodes are commonly used in varactor circuits to achieve automatic frequency control, tuning, frequency modulation, and scanning oscillation.

omnitronic electrical component classification

(1) Point-contact diodes have a small PN junction contact area, cannot pass large forward currents or withstand high reverse voltages, but offer good high-frequency performance, making them suitable for use in high-frequency detection and switching circuits. (2) Surface-contact diodes have a large PN junction contact area, can pass large currents, and can withstand high reverse voltages, making them suitable for use in rectifier circuits. (3) Planar diodes have a small PN junction area when used as switching tubes in pulse digital circuits, and a larger PN junction area when used for high-power rectification. (4) Zener diodes are a special type of surface-contact silicon semiconductor diode with voltage stabilization functionality. The main difference between Zener diodes and ordinary diodes is that Zener diodes operate in the reverse breakdown state of the PN junction. By implementing process measures during manufacturing and limiting the magnitude of reverse current during use, it is ensured that the Zener diode will not be damaged by overheating in the reverse breakdown state. Unlike general diodes, the reverse breakdown of a Zener diode is reversible; as long as the current does not exceed the allowable value for the Zener diode, the PN junction will not overheat and fail. When the external reverse voltage is removed, the Zener diode restores its original performance, so Zener diodes have good repetitive breakdown characteristics. (5) Photodiodes, also known as photosensitive diodes. Their casing is equipped with a glass window to facilitate light reception. Their characteristic is that when light irradiates their PN junction, electron-hole pairs are generated, increasing the concentration of minority carriers in the semiconductor. Under a certain reverse bias voltage, this causes the reverse current to increase. Therefore, their reverse current increases linearly with increasing light intensity. When there is no light illumination, the volt-ampere characteristics of a photodiode are the same as those of an ordinary diode. As light-controlled components, photodiodes can be used for object detection, photoelectric control, automatic alarms, and other applications. When made into large-area photodiodes, they can serve as an energy source and are called solar cells. In this case, they do not require an external power supply and can directly convert light energy into electrical energy. (6) Light-emitting diodes are solid-state semiconductor display devices that directly convert electrical energy into light energy, abbreviated as LED. Similar to ordinary diodes, light-emitting diodes are also composed of a PN junction. The PN junction of a light-emitting diode is encapsulated in a transparent plastic shell, with shapes including square, rectangular, and circular. Light-emitting diodes have advantages such as low drive voltage, small operating current, strong resistance to vibration and shock, small size, high reliability, low power consumption, and long service life, and are widely used in signal indication circuits. In electronic technology, commonly used seven-segment displays operate on a principle opposite to that of photodiodes. When a light-emitting diode is forward-biased and current passes through it, it emits light. This is the result of energy release when electrons and holes recombine directly. Its spectral range is relatively narrow, and its wavelength is determined by the base material used.
