Tippkemper-Matrix switch Germany Tippkemper-Matrix model Tippkemper-Matrix price

Tippkemper-Matrix switch is a device that converts magnetic signals into electrical signals. By utilizing the transformation relationship between magnetic quantities and other physical quantities, with the magnetic field as a medium, it can also convert other non-electrical physical quantity signals into electrical signals. There are two driving methods: one is driven by a permanent magnet, and the other is driven by an electromagnetic coil. The former is mostly used for detection; for example, if a moving part is made of a magnet, it will attract and emit a signal once it approaches the magnetic induction switch. The latter is mostly used for control; if the electromagnetic coil is energized, the contacts will attract. Using magnetic induction switches to replace limit switches that rely on collision contact can improve system reliability and service life; therefore, they are often used in programmable logic controllers as signaling devices for position arrival.

Tippkemper-Matrix switch classification

Lasers can be divided into 4 types according to the working medium. (1) Solid-state lasers: Their working medium is solid. Common examples 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: Their working medium is gas. There are now various gas atomic, ion, metal vapor, and gas molecular lasers. Common examples include carbon dioxide lasers, helium-neon lasers, and carbon monoxide lasers. Their shape is like ordinary discharge tubes, characterized by stable output, good monochromaticity, and long life, but lower power and lower conversion efficiency. (3) Liquid lasers: They can be further divided into chelate lasers, inorganic liquid lasers, and organic dye lasers, among which organic dye lasers are the most important. Their greatest characteristic is that the wavelength is continuously tunable. (4) Semiconductor lasers: They are a relatively young type of laser, among which gallium arsenide lasers are 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, the output power is relatively small, directivity is poor, and they are significantly affected by ambient temperature.

Tippkemper-Matrix switch principle

When a laser switch operates, the laser emitting diode first emits laser pulses toward the target. After reflection from the target, the laser scatters in all 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 functionality, 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 return and reception. Laser switches must measure transmission time extremely precisely because the speed of light is very fast.

Tippkemper-Matrix 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 switches. User-friendly upper computer control software was also 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 precise data about the vehicle itself and its surroundings. This data is analyzed and calculated by the processor inside the car, and the vehicle's movement is controlled 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 is a 360° rotating laser holographic switch, which can almost simultaneously sense the conditions in front of, to the side of, 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 to judge the condition of traffic ahead and control safe acceleration and deceleration of the vehicle. Position switches are also installed 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 calculate through software to 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.
