BOHMEXTRUPLAST electrical components Germany BOHMEXTRUPLAST model BOHMEXTRUPLAST price

BOHMEXTRUPLAST electrical components are a new type of contactless switching device composed entirely of solid-state electronic components. It utilizes the switching characteristics of electronic components (such as switching transistors, triacs, and other semiconductor devices) to achieve contactless, spark-free circuit connection and disconnection, hence it is also known as a "contactless switch." A solid-state relay is a four-terminal active device, where two terminals are input control terminals and the other two are output controlled terminals. It has both amplification drive and isolation functions, making it very suitable for driving high-power switching actuators. Compared with electromagnetic relays, it offers higher reliability, is contactless, has a long service life, fast speed, and low external interference, and has been widely applied [1].

BOHMEXTRUPLAST electrical components applications

The most widely used motors in various applications are AC asynchronous motors. They are easy to use, reliable, inexpensive, and robust in structure, but have a low power factor and difficult speed regulation. Synchronous motors are commonly used for high-capacity, low-speed prime movers. Synchronous motors not only have a high power factor, but their speed is independent of load size and depends only on the grid frequency, resulting in stable operation. DC motors are often used in applications requiring wide-range speed regulation. However, they have commutators, complex structures, high prices, and difficult maintenance, making them unsuitable for harsh environments. With the development of power electronics, AC motor speed control technology is maturing, equipment prices are decreasing, and they are beginning to be applied. The maximum output mechanical power that a motor can handle under a specified duty cycle without causing overheating is called its rated power; attention should be paid to the ratings on the nameplate during use. During motor operation, ensure that the load characteristics match the motor characteristics to avoid runaway or stalling. Motors can provide a wide range of power, from milliwatts to tens of megawatts. Motor use and control are very convenient, featuring capabilities such as self-starting, acceleration, braking, reversal, and holding. Generally, when a motor's speed is regulated, its output power changes with the speed.

BOHMEXTRUPLAST electrical components principle

In information technology, digital integrated circuits are the mainstay, processing information carried by digital signals, which take discrete values in time and magnitude. However, signals in nature change continuously in time and magnitude, such as wind sound and water flow; these are called analog signals. Correspondingly, circuits that process analog signals are called analog circuits, and integrated circuits used to process analog signals are called analog integrated circuits. Obviously, digital circuits cannot directly interface with the natural world; for the convenience of processing or transmission and to fully utilize the advantages of digital systems, analog signals are first converted into digital signals, input into modern digital systems with large capacity, high speed, strong anti-interference ability, and good confidentiality for processing, and then reconverted into analog signals for output. The main component of integrated circuits is the transistor, and analog integrated circuits are no exception. However, they utilize the amplification effect of transistors, whereas digital integrated circuits utilize the switching effect of transistors. Early analog integrated circuits mostly used bipolar transistors. Due to the maturity of CMOS technology, the disadvantage of slow speed in early CMOS circuits has been overcome, and it offers the advantages of low power consumption and convenient process upgrades (CMOS scaling). Nowadays, analog integrated circuits and mixed-signal integrated circuits (integrating digital and analog circuits) are also commonly designed and implemented using CMOS.

BOHMEXTRUPLAST electrical components performance

The main performance indicators of a loudspeaker include sensitivity, frequency response, rated power, rated impedance, directivity, and distortion. ① Rated power: Loudspeaker power is categorized into nominal power and maximum power. Nominal power, also referred to as rated power or non-distortion power, is the maximum input power allowed within the rated non-distortion range of the loudspeaker. The power value marked on the loudspeaker's label and technical manual corresponds to this rating. Maximum power refers to the peak power that the loudspeaker can withstand at any given instant. ② Rated impedance: The impedance of a loudspeaker is generally frequency-dependent. ③ Frequency response: When audio signals of the same voltage but different frequencies are applied to a loudspeaker, the resulting sound pressure level will vary. Typically, the sound pressure is higher in the mid-frequency range and lower in the low- and high-frequency ranges. The frequency range of high and low tones where the sound pressure drops to a certain value relative to the mid-frequency sound pressure is defined as the frequency response characteristic of the loudspeaker. ④ Distortion: Distortion refers to the phenomenon where the loudspeaker fails to accurately reproduce the original sound. There are two types of distortion: frequency distortion and nonlinear distortion. Frequency distortion occurs when certain frequency signals are reproduced with higher intensity while others are weaker, disrupting the original balance of high and low loudness and altering the timbre. Nonlinear distortion arises from inconsistencies between the vibration of the loudspeaker's moving system and the signal fluctuations, introducing new frequency components into the output sound waves. ⑤ Directivity characteristics: These describe the distribution of sound pressure radiated by the loudspeaker in various spatial directions. Higher frequencies result in narrower directivity, and larger diaphragms result in stronger directivity.
