SACH electrical components Germany SACH model SACH price

SACH electrical components is a general term for all single components based on semiconductor materials, including diodes, transistors, field-effect transistors, and thyristors made of various semiconductor materials (the latter three are all three-terminal devices). A transistor is a semiconductor device commonly used in amplifiers or electronically controlled switches. Transistors are the basic building blocks for the standard operation of computers, mobile phones, and all other modern electronic circuits. Due to their fast response speed and high accuracy, transistors can be used for a wide variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators. Transistors can be packaged individually or as part of an integrated circuit in a very small area that can accommodate one hundred million or more transistors.

SACH electrical components applications

Photoelectric sensors that use photoelectric elements as sensitive components come in many types and have a wide range of applications. According to the nature of the output quantity of the photoelectric sensor, they can be divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously changing photocurrent, which can be used to measure physical quantities such as light intensity, object temperature, light transmission capability, displacement, and surface condition. For example: illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters and turbidimeters, photoelectric alarms for fire prevention, and automatic detection devices and instruments for checking the diameter, length, ellipticity, and surface roughness of machined parts, all of which use photoelectric elements as sensitive components. Semiconductor photoelectric elements are not only widely used in the civil industrial field, but also hold an important position in military applications. For example, lead sulfide photoresistors can be used to make infrared night vision devices, infrared cameras, and infrared navigation systems; (10) Converting the measured quantity into a continuously changing photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "yes" or "no" electrical signals when exposed to light or no light. Photoelectric elements are used as switch-type photoelectric conversion elements. For example, photoelectric input devices for electronic computers, switch-type temperature control devices, and digital photoelectric tachometers for speed measurement.

SACH electrical components function

To obtain information from the external world, people must rely on their sensory organs. However, relying solely on human sensory organs is far insufficient for studying natural phenomena and laws, as well as for their functions in production activities. To adapt to this situation, sensors are required. Therefore, it can be said that sensors are an extension of the human five senses, also known as electronic five senses. With the advent of the new technological revolution, the world has begun to enter the information age. In the process of utilizing information, the primary issue to address is the acquisition of accurate and reliable information, and sensors are the main channels and means for obtaining information in the fields of nature and production. In modern industrial production, especially in automated production processes, various sensors are used to monitor and control various parameters in the production process, ensuring that equipment operates in a normal or optimal state and that products achieve the best quality. Therefore, it can be said that without numerous high-quality sensors, modern production would lose its foundation. In basic discipline research, sensors hold an even more prominent position. The development of modern science and technology has entered many new fields: for example, observing the vast universe thousands of light-years away on a macro scale, observing the particle world as small as fm on a micro scale, observing celestial evolution spanning hundreds of thousands of years vertically, and instantaneous reactions as short as s. In addition, various extreme technology studies have emerged, playing an important role in deepening the understanding of matter, exploring new energy sources, and developing new materials, such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, ultra-strong magnetic fields, and ultra-weak magnetic fields. Obviously, it is impossible to obtain a large amount of information that human senses cannot directly access without appropriate sensors. Many obstacles in basic scientific research lie first in the difficulty of acquiring object information, and the emergence of some new mechanisms and high-sensitivity detection sensors often leads to breakthroughs in these fields. The development of some sensors is often a pioneer in the development of interdisciplinary subjects. Sensors have long penetrated into extremely broad fields such as industrial production, space exploration, ocean exploration, environmental protection, resource surveys, medical diagnosis, bioengineering, and even cultural relic preservation. It is no exaggeration to say that from the vastness of space to the expanses of the ocean, and even various complex engineering systems, almost every modern project relies on various types of sensors.

SACH electrical components classification

There are multiple classification methods for thyristors: (1) Classification by turn-off, conduction, and control methods: Thyristors can be divided into ordinary thyristors, bidirectional thyristors, reverse-conducting thyristors, gate turn-off thyristors, BTG thyristors, temperature-controlled thyristors, and light-controlled thyristors according to their turn-off, conduction, and control methods. (2) Classification by pins and polarity: Thyristors can be divided into two-pin thyristors, three-pin thyristors, and four-pin thyristors according to their pins and polarity. (3) Classification by package form: Thyristors can be divided into three types: metal-packaged thyristors, plastic-packaged thyristors, and ceramic-packaged thyristors according to their package form. Among them, metal-packaged thyristors are further divided into bolt type, flat plate type, round shell type, etc.; plastic-packaged thyristors are divided into two types: with heat sink and without heat sink. (4) Classification by current capacity: Thyristors can be divided into high-power thyristors, medium-power thyristors, and low-power thyristors according to their current capacity. Usually, high-power thyristors mostly adopt metal shell packaging, while medium and low-power thyristors mostly adopt plastic or ceramic packaging. (5) Classification by turn-off speed: Thyristors can be divided into ordinary thyristors and high-frequency (fast) thyristors according to their turn-off speed. (6) Zero-crossing trigger - generally for power adjustment, i.e., triggering when the phase of the sinusoidal AC voltage crosses zero; triggering must occur at the zero-crossing point to conduct the thyristor. (7) Non-zero-crossing trigger - the thyristor can be triggered to conduct regardless of the phase of the AC voltage; common is phase-shift triggering, i.e., changing the output percentage by changing the conduction angle (phase angle) of the sinusoidal AC current.
