Turck Banner electrical component features

LED lamps are light-emitting diodes that use solid-state semiconductor chips as the light-emitting material. Compared with traditional lamps, LED lamps are energy-saving, environmentally friendly, and offer good color rendering and response speed. (1) Energy saving is the most prominent feature of LED lamps in terms of energy consumption; the energy consumption of LED lamps is one-tenth that of incandescent lamps and one-quarter that of energy-saving lamps. This is a major feature of LED lamps. People today advocate energy conservation and environmental protection, and it is precisely because of this energy-saving feature that LED lamps have a wide range of applications and are very popular. (2) Can operate in high-speed switching states. When we walk on the street, we find that every screen or image composed of LED is ever-changing. This shows that LED lamps can perform high-speed switching operations. However, the incandescent lamps we usually use cannot achieve this working state. In daily life, if the switch is operated too many times, it will directly cause the filament of the incandescent lamp to break. This is also an important reason why LED lamps are popular. (3) Environmental protection: LED lamps do not contain any heavy metal materials such as mercury, whereas fluorescent lamps do, which reflects the environmental friendliness of LED lamps. People now attach great importance to environmental protection, so more people are willing to choose environmentally friendly LED lamps. (4) Fast response speed is another prominent feature of LED lamps, namely their fast reaction speed. As soon as the power is connected, the LED lamp lights up immediately. Compared with the energy-saving lamps we usually use, their response speed is faster. When turning on traditional bulbs, it often takes a long time to illuminate the room, and they only light up after the bulb has completely heated up. (5) Compared with other light sources, LED lamps are "cleaner". The so-called "clean" does not refer to the cleanliness of the lamp surface and interior, but rather that the lamp is a cold light source, does not generate excessive heat, and does not attract insects that are attracted to light and heat. Especially in summer, there are many insects in rural areas. Some insects are naturally heat-loving; incandescent lamps and energy-saving lamps generate heat after being used for a period of time, and this heat is exactly what insects like, making it easy to attract them. This will undoubtedly bring many pollutants to the lamp surface, and insect excrement will also make the indoor environment very dirty. However, LED lamps are cold light sources and do not attract insects, so no insect excrement is produced. Therefore, LED lamps are "cleaner". Semiconductor light-emitting diodes have a wide range of applications, low power consumption, long service life, and are low-carbon and environmentally friendly. The application of semiconductor light-emitting diodes in China is very extensive; many lighting devices in residential homes use semiconductor light-emitting diodes, and most street lights also use semiconductor light-emitting diode street lights as lighting sources. Some road lighting fixtures also combine solar technology, which can save a large amount of electrical energy. Photosensitive diodes can be divided into gallium aluminum arsenide photosensitive diodes, aluminum phosphide arsenide photosensitive diodes, gallium phosphide photosensitive diodes, and aluminum arsenide photosensitive diodes, depending on the material.

Turck Banner electrical component principles

Optical measurement and control systems are diverse, manufactured based on different principles of how luminous flux acts on photoelectric elements. According to the nature of the output of the photoelectric element (optical measurement and control system), they can be divided into two categories: analog photoelectric sensors and pulse (switching) photoelectric sensors. Analog photoelectric sensors convert the measured quantity into a continuously changing photocurrent, exhibiting a single-valued relationship with the measured quantity. Analog photoelectric sensors can be divided into three major categories based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and shading (beam blocking) type. The transmission type refers to placing the measured object in the optical path; the light energy emitted by a constant light source passes through the measured object, and after partial absorption, the transmitted light is projected onto the photoelectric element. The diffuse reflection type refers to light emitted by a constant light source being projected onto the measured object, reflecting off its surface, and then being projected onto the photoelectric element. The shading type refers to when the luminous flux emitted by the light source is partially blocked by the measured object, causing a change in the luminous flux projected onto the photoelectric element; the degree of change is related to the position of the measured object in the optical path. Photodiodes are the most common optical sensors. The appearance of a photodiode is similar to that of a general diode. When there is no light, it behaves like a ordinary diode with a very small reverse current, known as the dark current of the photodiode. When illuminated, carriers are excited, generating electron-hole pairs, known as photoelectric carriers. Under the influence of an external electric field, these photoelectric carriers participate in conduction, forming a reverse current much larger than the dark current, which is called the photocurrent. The magnitude of the photocurrent is proportional to the light intensity, so an electrical signal that varies with light intensity can be obtained across the load resistor.

Turck Banner electrical component parameters

1. Voltage temperature coefficient: Refers to the rate of change of the nominal voltage of a varistor within a specified temperature range, i.e., the relative change in voltage across the varistor when the temperature changes while the current through the varistor remains constant. 2. Current temperature coefficient: Refers to the relative change in current flowing through the varistor when the temperature changes while the voltage across the varistor remains constant. 3. Nominal voltage: Refers to the voltage value across the varistor when a DC current is passed through it. 4. Voltage ratio: Refers to the ratio of the voltage generated by the current in the varistor to the voltage generated by the current in the varistor. 5. Maximum limiting voltage: Refers to the highest voltage value that the varistor can withstand across its terminals. 6. Leakage current: Also known as standby current, it refers to the current flowing through the varistor at a specified temperature and maximum DC current. 7. Residual voltage ratio: When the current passing through the varistor is a certain value, the voltage generated across its terminals is called the residual voltage for that current value. The residual voltage ratio is the ratio of the residual voltage to the nominal voltage. 8. Surge current capacity: Also known as surge current, it refers to the maximum pulse (peak) current value allowed to pass through the varistor under specified conditions (specified time intervals and number of times, applying standard impulse current). 9. Static capacitance: Refers to the inherent capacitance of the varistor itself. 10. Insulation resistance: Refers to the resistance value between the leads (pins) of the varistor and the insulated surface of the resistive body. 16. Voltage nonlinearity coefficient: Refers to the ratio of the static resistance value to the dynamic resistance value of the varistor under a given applied voltage.
