vitramo electrical components Germany vitramo model vitramo price

vitramo electrical components are sensors that convert the state of a measured object into measurable optical signals. The working principle of a fiber optic sensor is to guide the light beam from the light source into a modulator via an optical fiber. Inside the modulator, interaction with external measured parameters causes changes in the optical properties of the light, such as intensity, wavelength, frequency, phase, and polarization state, resulting in a modulated optical signal. This signal is then transmitted via optical fiber to a photodetector and demodulated to obtain the measured parameters. Throughout this process, the light beam is introduced via the optical fiber, passes through the modulator, and is then emitted, where the function of the optical fiber is first to transmit the light beam, and second to act as an optical modulator.

vitramo electrical component performance

The performance of fiber optic connectors primarily involves optical performance, but also considers interchangeability, repeatability, tensile strength, temperature resistance, and mating cycles. 1. Optical performance: The main requirements for the optical performance of fiber optic connectors are insertion loss and return loss, which are the two most basic parameters. Insertion loss, also known as connection loss, refers to the loss of effective optical power in the link caused by the introduction of the connector. Lower insertion loss is better, and it is generally required to be no greater than 0.5dB. Return loss refers to the ability of the connector to suppress reflection of optical power in the link, and its typical value should be no less than 25dB. For connectors in practical applications, the ferrule surface undergoes specialized polishing treatment, which can increase return loss, generally not lower than 45dB. 2. Interchangeability and repeatability: Fiber optic connectors are universal passive components. Connectors of the same type can generally be combined arbitrarily and reused multiple times, with the additional loss introduced thereby generally being less than 0.2dB. (3) Tensile strength: For assembled fiber optic connectors, the tensile strength is generally required to be no less than 90N. (4) Temperature: Generally, fiber optic connectors must operate normally within a temperature range of -40oC to +70oC. (5) Mating cycles: Most fiber optic connectors used can withstand more than l004 mating cycles.

Modulated pulses generated by the oscillation circuit pass through the reflection circuit, and light pulses are radiated 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 and shaped. Digital integration or RC integration is then used to eliminate interference. Finally, the photoelectric switch control signal is output by the driver trigger after a delay (or without delay). Photoelectric switches generally have good hysteresis characteristics, so even if the detected object shakes within a small range, the output status of the driver will not be affected, keeping it in a stable operating zone. Meanwhile, the self-diagnostic system can display the light reception 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. They are also applied in daily life, such as in automatic doors in hotels, restaurants, and garages, and in automatic hot air blowers. For security and anti-theft purposes, important locations 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; and in control technology, such as measurement and control of displacement, speed, and acceleration, a large number of proximity switches are also used.

To obtain information from the external world, humans must rely on 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 channel 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, and 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 obtaining 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 the pioneer of interdisciplinary development. Sensors have long penetrated into extremely broad fields such as industrial production, space exploration, ocean detection, environmental protection, resource survey, medical diagnosis, bioengineering, and even cultural relic preservation. It is no exaggeration to say that from the vast space to the extensive oceans, and even various complex engineering systems, almost every modern project relies on various types of sensors.
