eberle electrical components Germany eberle model eberle price

eberle electrical components are devices that provide detachable (active) connections between optical fibers. They precisely align the end faces of two optical fibers to maximize the coupling of light energy from the transmitting fiber into the receiving fiber, while minimizing the impact on the system caused by their insertion into the optical link. These are the basic requirements for fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and various performance metrics of optical transmission systems.

eberle electrical components features

Among various types of switches, there is a component with the ability to "sense" objects approaching it—the displacement sensor. Proximity switches utilize the sensitivity of displacement sensors to approaching objects to control the opening or closing of the switch. When an object moves toward the proximity switch and reaches a certain distance, the displacement sensor "senses" it, causing the switch to actuate. This distance is typically referred to as the "detection distance." Different proximity switches have different detection distances. Sometimes, detected objects move toward the proximity switch one by one at certain time intervals and then leave one by one, repeating this process continuously. Different proximity switches have different response capabilities to detection objects. This response characteristic is known as the "response frequency."

eberle electrical components function

When the distance between an observer or system and a wave source changes, the frequency of the approaching waves shifts. This phenomenon is called the Doppler effect. Sonar and radar are developed based on this principle. The Doppler effect can be used to create ultrasonic proximity switches, microwave proximity switches, etc. When an object approaches, the reflected signal received by the proximity switch undergoes a Doppler frequency shift, allowing the identification of whether an object is approaching. 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 locations such as archives, accounting departments, financial institutions, museums, and vaults are typically equipped with anti-theft devices composed of various proximity switches. In measurement technology, such as for length and position; and in control technology, such as for the measurement and control of displacement, speed, and acceleration, a large number of proximity switches are also used.
