NIEDAXKLEINHUIS electrical components Germany NIEDAXKLEINHUIS model NIEDAXKLEINHUIS price

NIEDAXKLEINHUIS electrical component is a high-power electrical component, also known as a thyristor. It has the advantages of small size, high efficiency, and long service life. In automatic control systems, it can serve as a high-power drive device, enabling low-power control elements to control high-power equipment. It is widely used in AC/DC motor speed control systems, power regulation systems, and servo systems. Thyristors are divided into unidirectional thyristors and bidirectional thyristors. Bidirectional thyristors are also called triac bidirectional thyristors, abbreviated as TRIAC. A bidirectional thyristor is structurally equivalent to two unidirectional thyristors connected in reverse, providing bidirectional conduction capability. Its on/off state is determined by the gate G. Applying a positive pulse (or negative pulse) to the gate G enables forward (or reverse) conduction. The advantages of this device include a simple control circuit and no reverse voltage withstand issue, making it particularly suitable for use as an AC contactless switch.

NIEDAXKLEINHUIS electrical component principle

Photoelectric sensors generally consist of 2 parts: processing channels and processing elements. Their basic principle is based on the photoelectric effect, converting changes in the measured quantity into changes in optical signals, and then using photoelectric elements to further convert non-electrical signals into electrical signals. The photoelectric effect refers to the phenomenon where light irradiating an object can be viewed as a stream of photons with specific energy bombarding the object. At this point, photon energy is transferred to electrons, with the entire energy of one photon being absorbed by one electron at once. After gaining energy from the photons, the state of the electrons changes, causing corresponding electrical effects in the irradiated object. The photoelectric effect is usually classified into 5 categories: (1) The phenomenon where electrons escape from the surface of an object under light irradiation is called the external photoelectric effect, such as in phototubes and photomultiplier tubes; (2) The phenomenon where the resistivity of an object changes under light irradiation is called the internal photoelectric effect, such as in photoresistors and phototransistors; (3) The phenomenon where an object generates an electromotive force in a specific direction under light irradiation is called the photovoltaic effect, such as in photocells. Photoelectric detection methods offer advantages such as high precision, fast response, and non-contact operation. They can measure multiple parameters, and the sensor structure is simple and flexible. Therefore, photoelectric sensors are widely used in detection and control. Photoelectric sensors are key components in various photoelectric detection systems for achieving photoelectric conversion; they are devices that convert optical signals (visible and ultraviolet laser light) into electrical signals. Photoelectric sensors use photoelectric devices as conversion elements. They can detect non-electrical physical quantities that directly cause changes in light intensity, such as light intensity, illuminance, radiation temperature measurement, and gas composition analysis. They can also detect other non-electrical quantities that can be converted into changes in light intensity, such as part diameter, surface roughness, strain, displacement, vibration, speed, acceleration, as well as object shape and working status recognition. Photoelectric sensors feature non-contact operation, fast response, and reliable performance, leading to widespread application in industrial automation devices and robotics. The continuous emergence of new photoelectric devices, especially the advent of CCD image sensors, has opened a new chapter for the further application of photoelectric sensors.

NIEDAXKLEINHUIS electrical component classification

Plug-in fuses are often used at the end of lines for short-circuit protection of distribution branch circuits or electrical equipment. Spiral fuses have a fuse indicator on the upper cap of the fusible element. Once the fusible element melts, the indicator pops out immediately and can be observed through the glass hole on the ceramic cap. They are commonly used in machine tool electrical control equipment. Spiral fuses. Enclosed fuses are divided into filled fuses and unfilled fuses. Filled fuses generally use square ceramic tubes containing quartz sand and the fusible element, offering strong breaking capacity. Unfilled enclosed fuses enclose the fusible element in a sealed cylinder, having slightly lower breaking capacity. Fast-acting fuses are mainly used for short-circuit protection of semiconductor rectifier elements or rectifier units. Since semiconductor components have very low overload capacity and can only withstand large overload currents for extremely short periods, short-circuit protection requires fast-acting fusing capability. The structure of fast-acting fuses is basically the same as that of filled enclosed fuses, but the material and shape of the fusible element differ. It uses a silver sheet stamped into a variable cross-section fusible element with V shaped deep grooves. Fast-acting fuses are commonly referred to as "fast fuses," characterized by fast fusing speed, high rated current, strong breaking capacity, stable current-limiting characteristics, and small size. Self-resetting fuses use sodium metal as the fusible element, which has high electrical conductivity at room temperature. When a short-circuit fault occurs in the circuit, the short-circuit current generates high temperature, causing the sodium to vaporize rapidly. The gaseous sodium presents a high-resistance state, thereby limiting the short-circuit current. After the short-circuit current disappears and the temperature drops, the sodium metal restores its original good conductivity. Self-resetting fuses can only limit short-circuit current and cannot truly break the circuit. Their advantage is that the fusible element does not need to be replaced, allowing for repeated use.

NIEDAXKLEINHUIS electrical component characteristics

Sensitivity refers to the ratio of the change in output to the change in input when the sensor is operating in a steady state. It is the slope of the output-input characteristic curve. If there is a linear relationship between the sensor's output and input, then the sensitivity S is a constant. Otherwise, it will vary with changes in the input. The dimension of sensitivity is the ratio of the dimensions of the output and input quantities. When the dimensions of the sensor's output and input quantities are the same, sensitivity can be understood as the amplification factor. Increasing sensitivity yields higher measurement precision. However, the higher the sensitivity, the narrower the measurement range, and stability often deteriorates.
