traub electrical components Germany traub model traub price

traub electrical components refer to electronic components that generate resonant frequencies, commonly divided into quartz crystal resonators and ceramic resonators. They function to generate frequency, featuring stability and good anti-interference performance, and are widely used in various electronic products. The frequency accuracy of quartz crystal resonators is higher than that of ceramic resonators, but the cost is also higher. Resonators mainly serve the role of frequency control; all electronic products involving frequency transmission and reception require resonators. Resonator types can be divided into through-hole and surface-mount types based on their form factor.

traub electrical component performance

1. Protection characteristics: When the impact strength from the surge source does not exceed the specified value, the clamping voltage of the varistor must not exceed the impulse withstand voltage that the protected object can endure. 2. Surge withstand characteristics: The varistor itself must be able to withstand the specified surge current, surge energy, and the average power when multiple surges occur sequentially. 3. Life characteristics include two aspects: one is the continuous operating voltage life, meaning the varistor should reliably operate for a specified time (in hours) under specified ambient temperature and system voltage conditions; the other is surge life, meaning it can reliably withstand a specified number of surges. 5. After the varistor is integrated into the system, in addition to acting as a "safety valve" for protection, it introduces some additional effects, known as "secondary effects," which should not degrade the normal operating performance of the system. The main factors to consider at this stage are three: first, the inherent capacitance of the varistor; second, the leakage current under system voltage; and third, the influence of the varistor's nonlinear current coupling through the source impedance on other circuits.

traub electrical component classification

1. By application: pressure-sensitive and force-sensitive sensors, position sensors, liquid level sensors, energy consumption sensors, speed sensors, acceleration sensors, radiation sensors, thermal sensors. 2. By principle: vibration sensors, humidity-sensitive sensors, magnetic-sensitive sensors, gas-sensitive sensors, vacuum degree sensors, biological sensors, etc. 3. By output signal: (1) Analog sensors convert the measured non-electrical quantity into an analog electrical signal. (2) Digital sensors: Convert the measured non-electrical quantity into a digital output signal (including direct and indirect conversion). (3) Pseudo-digital sensors: Convert the measured signal quantity into a frequency signal or short-period signal output (including direct or indirect conversion). (4) Switch sensors: When a measured signal reaches a specific threshold, the sensor correspondingly outputs a set low-level or high-level signal. 4. By manufacturing process: Integrated sensors are manufactured using standard production processes for silicon-based semiconductor integrated circuits. Usually, part of the circuitry for preliminary processing of the measured signal is also integrated on the same chip. Thin-film sensors are formed by depositing thin films of corresponding sensitive materials on a dielectric substrate (base plate). When using hybrid processes, part of the circuitry can also be fabricated on this substrate. Thick-film sensors are made by coating slurries of corresponding materials onto ceramic substrates, typically made of alumina, followed by heat treatment to form the thick film. Ceramic sensors are produced using standard ceramic processes or certain variants (sol-gel, etc.). After appropriate preparatory operations, the formed elements are sintered at high temperatures. There are many common characteristics between thick-film and ceramic sensor processes; in some respects, the thick-film process can be considered a variant of the ceramic process. Each process technology has its own advantages and disadvantages. Due to lower capital investment required for research, development, and production, as well as the high stability of sensor parameters, it is more reasonable to adopt ceramic and thick-film sensors. 5. By measurement objective: Physical sensors are made using characteristics where certain physical properties of the measured substance undergo significant changes. Chemical sensors are made using sensitive elements that can convert chemical quantities such as composition and concentration of chemical substances into electrical quantities. Biological sensors are made using various biological or biomaterial characteristics to detect and identify chemical components in biological bodies. 6. By composition: (1) Basic sensors are the most fundamental single transformation devices. (2) Combined sensors are sensors composed of different single transformation devices. (3) Application-specific sensors are sensors composed of basic or combined sensors combined with other mechanisms. 17. By mode of action: Sensors can be divided into active and passive types based on their mode of action. Active sensors include actuating and reaction types. Such sensors can emit a certain detection signal towards the measured object, detect changes produced in the measured object by the detection signal, or form a signal by generating a certain effect in the measured object via the detection signal. Those detecting changes in the detection signal are called actuating type; those detecting responses to form signals are called reaction type. Radar and radio frequency range detectors are examples of actuating type, while photoacoustic effect analysis devices and laser analyzers are examples of reaction type. Passive sensors only receive signals generated by the measured object itself, such as infrared radiation thermometers and infrared imaging devices.

traub electrical component requirements

1, Copper and aluminum rods commonly used for power cables are drawn through one or several drawing dies at room temperature using a wire drawing machine, reducing their cross-section, increasing their length, and improving their strength. Wire drawing is the first process in wire and cable companies, and the primary process parameter is die matching craftsmanship. 2, Copper and aluminum single wires are heated to a certain temperature to improve toughness and reduce strength through recrystallization, meeting the requirements for conductive cores in wires and cables. The key to the annealing process is to prevent oxidation of copper wires. 3, To improve the flexibility of power cables for easier installation, conductive cores are made by stranding multiple single wires. Stranding methods for conductive cores can be divided into regular stranding and irregular stranding. Irregular stranding is further divided into bunch stranding, concentric compound stranding, and special stranding. To reduce the occupied area of conductors and the geometric size of power cables, compacted methods are adopted during stranding, changing the usual circular shape into semi-circular, sectoral, tile-shaped, and compacted circular shapes. Such conductors are primarily used in power cables. 4, Plastic power cables mainly adopt extruded solid insulation layers. The deviation in insulation thickness is a major indicator of extrusion process quality. Most product structural dimensions and their deviations are clearly specified in standards. The surface of the plastic insulation layer must be smooth, without defects such as roughness, scorching, or impurities. The cross-section of the insulation layer must be dense and robust, with no visible pinholes or bubbles allowed. 5, Multi-core power cables generally need to be stranded into a circular shape to ensure form stability and reduce cable profile. The mechanism of cabling is similar to conductor stranding; due to the larger lay length, non-back-twist methods are mostly used. Technical requirements for cabling include: first, preventing twisting of the cable caused by flipping of shaped insulated cores; second, avoiding damage to the insulation layer. Most cables undergo two additional processes during cabling: filling, to ensure the roundness and stability of the cable after cabling; and binding, to prevent the cable core from loosening. 6, To protect insulated cores from damage by armor, appropriate protection is required for the insulation layer. Inner sheaths are divided into extruded inner sheaths (separation sleeves) and wrapped inner sheaths (cushioning layers). Wrapped cushioning layers replace binding tapes and are performed synchronously with the cabling process. 7, For power cables laid underground that may withstand certain positive pressure during operation, an internal steel tape armor structure can be selected. For power cables laid in locations subject to both positive pressure and tensile forces (such as in water, vertical shafts, or soil with significant drops), structures with internal steel wire armor should be selected. 16, The outer sheath is the structural part that protects the insulation layer of the power cable from environmental corrosion. The main functions of the outer sheath are to improve the mechanical strength of the power cable, resist chemical corrosion, prevent moisture, prevent water ingress, and inhibit combustion. Depending on different requirements for power cables, plastic sheaths are directly extruded using an extruder.
