BANNER electrical components, Germany BANNER models, BANNER prices

BANNER electrical components are detection devices that can sense measured information and convert the sensed information into electrical signals or other required forms of output according to specific rules, to meet requirements for information transmission, processing, storage, display, recording, and control. The existence and development of sensors have given objects senses such as touch, taste, and smell, bringing them to life; sensors are an extension of human senses. Sensors feature miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. They are the primary link in achieving automatic detection and automatic control. A device or apparatus that can sense a specified measured quantity and convert it into a usable signal according to a certain rule (mathematical function law), typically composed of a sensitive element and a conversion element.

BANNER electrical component classification

1. By application: pressure-sensitive and force-sensitive sensors, position sensors, 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, biosensors, etc. 3. By output signal: (1) Analog sensors can convert non-electrical measured quantities into analog electrical signals. (2) Digital sensors: convert non-electrical measured quantities into digital output signals (including direct and indirect conversion). (3) Quasi-digital sensors: convert the measured signal quantity into frequency signals or short-period signal outputs (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 circuit 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 circuit can also be fabricated on this substrate. Thick-film sensors are made by coating slurry of corresponding materials onto ceramic substrates, usually made of alumina, followed by heat treatment to form the thick film. Ceramic sensors are produced using standard ceramic processes or their 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 aspects, thick-film technology can be considered a variant of ceramic technology. 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 purpose: Physical sensors are made using the characteristic that 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 living organisms. 6. By composition: (1) Basic sensors are the most fundamental single conversion devices. (2) Combined sensors are sensors composed of different single conversion devices. (3) Application-specific sensors are sensors composed of basic sensors or combined sensors combined with other mechanisms. 11. By mode of action: Sensors can be divided into active and passive types based on their mode of action. Active sensors include actuating and reacting types. Such sensors can emit a certain detection signal to 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 by the detection signal. Those that detect changes in the detection signal are called actuating type, while those that detect responses to form signals are called reacting type. Radar and radio frequency range detectors are examples of actuating type, while photoacoustic effect analysis devices and laser analyzers are examples of reacting type. Passive sensors only receive signals generated by the measured object itself, such as infrared radiation thermometers and infrared imaging devices.

BANNER electrical component functions

Modulated pulses generated by the oscillation circuit pass through the reflection circuit and are radiated as light pulses by the LED GL. When the measured object enters the effective range of the receiver, the reflected light pulses enter the phototransistor DU. In the receiving circuit, the light pulses are demodulated into electrical pulse signals, amplified and synchronously gated/shaped by an amplifier, and then interference is eliminated using digital integration or RC integration methods. Finally, a driver is triggered with or without delay to output the photoelectric switch control signal. Photoelectric switches generally have good hysteresis characteristics, so even if the detected object shakes within a small range, it will not affect the output state of the driver, thereby keeping it in a stable operating zone. Meanwhile, the self-diagnosis system can display the light-receiving status and stable operating zone to monitor the work of the photoelectric switch at any time. Proximity switches are widely used in aviation, aerospace technology, and industrial production. In daily life, they are applied in automatic doors in hotels, restaurants, and garages, as well as in automatic hot air blowers. For security and anti-theft purposes, important places such as archives, accounting departments, financial institutions, museums, and vaults are usually equipped with anti-theft devices composed of various proximity switches. In measurement technology, such as length and position measurement; in control technology, such as displacement, speed, and acceleration measurement and control, a large number of proximity switches are also used.

1, By nature of operation, they can be divided into transmitting antennas and receiving antennas. 2, By application, they can be divided into communication antennas, broadcast antennas, television antennas, radar antennas, etc. 3, By directionality, they can be divided into omnidirectional antennas and directional antennas, etc. 4, By operating wavelength, they can be divided into ultra-long wave antennas, long wave antennas, medium wave antennas, short wave antennas, ultra-short wave antennas, microwave antennas, etc. 5, By structural form and working principle, they can be divided into wire antennas and aperture antennas, etc. Characteristic parameters describing antennas include radiation pattern, directivity coefficient, gain, input impedance, radiation efficiency, polarization, and bandwidth. 6, By dimension, they can be divided into two types: (1) One-dimensional antennas consist of many wires, which may be straight lines like those used in mobile phones, or clever shapes like the old 'rabbit ear' antennas used on televisions before cable TV. Monopole and dipole antennas are the two most basic one-dimensional antennas. (2) Two-dimensional antennas: diverse varieties, including patch (a square piece of metal), array (an organized bundle of patches in a two-dimensional pattern), horn, and dish. 13, Antennas can be classified into three major categories based on usage scenarios: handheld transceiver antennas, vehicle-mounted antennas, and base station antennas. Handheld transceiver antennas: antennas for personal use with handheld walkie-talkies, commonly rubber antennas and telescopic antennas. Vehicle-mounted antennas: communication antennas originally designed for installation on vehicles, with suction cup antennas being the most common and widespread application. Vehicle-mounted antenna structures also include shortened types, quarter-wavelength, center-loaded, five-eighths wavelength, and half-wave dipole types. Base station antennas: play a very critical role in the entire communication system, especially as communication hubs. Commonly used base station antennas include fiberglass high-gain antennas, four-ring array antennas (eight-ring array antennas), and directional ant
