Euchner switch Germany Euchner model Euchner price

Euchner switch is a switch that uses laser technology for measurement. It consists of a laser, a laser detector, and a measurement circuit. Laser switches are new types of measuring instruments. Their advantages include the ability to perform non-contact long-distance measurement, high speed, high precision, large measuring range, and strong resistance to optical and electrical interference.

Euchner switch classification

Lasers can be divided into 4 types according to the working medium. (1) Solid-state lasers: The working medium is solid. Common types include ruby lasers, neodymium-doped yttrium aluminum garnet lasers (i.e., YAG lasers), and neodymium glass lasers. Their structures are roughly similar, characterized by being small, robust, and high-power. Neodymium glass lasers are devices with the highest pulsed output power, reaching tens of megawatts. (2) Gas lasers: The working medium is gas. Various gas atomic, ion, metal vapor, and gas molecular lasers now exist. Common types include carbon dioxide lasers, helium-neon lasers, and carbon monoxide lasers. Their shape resembles ordinary discharge tubes, characterized by stable output, good monochromaticity, and long life, but lower power and lower conversion efficiency. (3) Liquid lasers: These can be further divided into chelate lasers, inorganic liquid lasers, and organic dye lasers. Among them, organic dye lasers are the most important, with the main characteristic of continuously tunable wavelength. (4) Semiconductor lasers: This is a relatively young type of laser, with gallium arsenide lasers being more mature. Characteristics include high efficiency, small size, light weight, and simple structure, making them suitable for carrying on aircraft, warships, tanks, and by infantry. They can be made into rangefinders and sights. However, they have lower output power, poorer directionality, and are significantly affected by ambient temperature.

Euchner switch principle

When a laser switch operates, the laser emission diode first emits laser pulses toward the target. After reflection from the target, the laser scatters in various directions. Part of the scattered light returns to the switch receiver, is received by the optical system, and is imaged onto an avalanche photodiode. An avalanche photodiode is an optical switch with internal amplification capability, so it can detect extremely weak light signals and convert them into corresponding electrical signals. A common type is the laser distance-measuring switch, which determines the target distance by recording and processing the time elapsed from the emission of the light pulse to its reception. Laser switches must measure transmission time with extreme precision because the speed of light is very fast.

Euchner switch applications

Over-limit detection of vehicle width and height: Laser switches are used for rapid measurement. The network kernel of the PC industrial PC and visualization programming software VB is utilized for real-time data transmission and processing with the switch. User-friendly host computer control software has also been designed. Field test data shows that the system has good real-time performance and high measurement accuracy, possessing certain practical value. Highway toll stations: Used at highway toll stations for vehicle counting and safety protection. Malaysia's Teras company has already applied hundreds of sets of BEA laser switches in its manual and automatic toll station systems. The laser switch adopts the Time of Flight (TOF) measurement principle, forming 4 planes within the detection area to detect vehicles. Meanwhile, the product also features functions such as anti-rear-end collision and vehicle safety protection. Compared with traditional light curtains, laser switches offer advantages such as high sensitivity, high precision, convenient installation, high cost-performance ratio, and strong stability. Google's second-generation driverless car: Equipped with laser switches. In Google's second-generation autonomous vehicle prototype, besides the laser switch on the top which remains quite obvious, other switches are set very discreetly. Obvious Google driverless car logos are posted on the front, rear, and both sides of the vehicle. The control and driving principle of the Google driverless car involves numerous switches installed around the car, continuously collecting various precise data about the vehicle itself and its surroundings. The processor inside the car analyzes and calculates this data, then controls the vehicle's movement based on the calculation results. The driverless car uses GPS equipment and switches to accurately locate the vehicle's position and forward speed, judging surrounding pedestrians, vehicles, bicycles, traffic lights, and many other objects. On the roof of this Lexus, there is a 360° rotating laser holographic switch, which can almost simultaneously sense the conditions in front of, beside, and behind the car. Data collected by the switch is input via green data cables into the processor located on the right rear side of the vehicle. This laser switch also allows the driverless car to achieve global precise positioning. The original L type Lexus emblem on the front of the car was removed and replaced with a radar switch, used to measure the distance ahead and vehicle speed, thereby judging the traffic conditions ahead and controlling safe acceleration and deceleration of the vehicle. Position switches are also mounted on the tire hubs to detect wheel rotation, helping the vehicle with positioning. The heart of the Google driverless car—the processor—is located on the right rear side of the vehicle. Data information from various switches is transmitted here via data wires, where it is analyzed and processed by software for precise sensing and judgment of different objects near the driverless car. In addition to analyzing and judging the current positions of objects around the driverless car, the vehicle needs to use software to calculate and accurately predict the possible next position of each object. Finally, the driverless car makes safe driving decisions based on all collected data, including controlling vehicle speed and distance from surrounding vehicles.
