Magnetic direct drive

Magnetic direct drive for high velocity industrial scanning applications Magnetic direct drives offer less friction, play, and therefore more precision over the classical motorized, spindle-based drives. For high-velocity industrial scanning applications, the company Physik Instrumente, a global player for precision positioning technology supplies the drive and positioning systems which make use of magnetic direct drives. With its friction-free magnetic drives PIMag series offers linear travels ranging from 5 to 20 mm, which reach the highest velocities up to 250 mm/s and scanning frequencies of some 10 Hz. These drives are particularly suitable for applications that require 24/7 operation, for example, in metrology, photonics, for image stabilization systems, in semiconductor and flatscreen inspection. Due to its crossed roller guides, the linear stage attains a travel accuracy of 1 µm. Its optical linear encoder allows a reliable position control and repeatability of ±500 nm. The sensor resolution is less than 10 nm; the minimum incremental motion is 20 nm. This direct drive series is also only 80 mm in width and 26 mm in height. Optical encoder with high precision Hengstler’s ‘Acuro-AX73’ series of optical encoders carries international certification for gas and dust explo sion protection which makes it suitable for use in hazardous environments. Apart from safety, precision is another beneficial characteristic of the Acuro AX73. The optical scanning system provides a highly accurate, 22-bit resolution sensor signal for areas wherever precision or smooth speed regulation is necessary. However, despite its accuracy, the encoder is of robust design, with impressive resistance to shock, vibration and external magnetic fields. In addition, the unit provides users with IP67 protection class rating for the stainless steel housing, with an ambient temperature range of -40 to +70 °C. AX73 has a housing diameter of 76 mm, which proves valuable to system designers seeking space-saving solutions. Available immediately, the AX73 can be ordered with SSI, BiSS-B, BiSS-C and Profibus interfaces. This advanced optical encoder offers significant cost and time savings during installation. The introduction of the AX73 completes the company’s comprehensive family of ATEX-rated absolute rotary encoders, both optical and magnetic.

Venturing into newer pastures Christof Kirsch Continental, the German giant in automotive industry is venturing into newer areas of business. Aiming to create new technologies, adding value to current ones and also securing its medium to long term stream of revenue generation. Continental, the tech company specializing in the automotive sector is now intensifying its activities outside its core areas and further expanding its industrial business. In the days to come, Continental will increasingly be focusing on technologies for construction, agriculture, and material handling equipment. With this in mind, the company based in Hannover, Germany is consistently working toward its strategic aim of achieving a more balanced customer portfolio across the automotive sector and other industries. In doing so, it also safeguards the future viability of the company in the face of possible economic fluctuations. Based on current forecasts, the company sees great opportunities and is targeting a sales potential in the higher triple-digit million Euros by 2020. The off-highway product portfolio, which the company is aiming to strengthen, ranges from electronic control units and instrumentation to solutions for telematics, display systems as well as technologies for drive and exhaust-gas after treatment, conveyor belts, vibration and hose technology, air spring systems, and interior materials. About Continental As an international automotive supplier, Continental, in 2015, generated sales of € 39.2 billion with its 5 divisions, Chassis & Safety, Interior, Powertrain, Tyres, and ContiTech. As a division in the Continental group, ContiTech is one of the world’s leading industrial specialists. Its customers can be found in key industries such as machine and plant engineering, mining, the agricultural industry, and the automotive industry. With around 43,000 employees in 44 countries and sales of € 5.4 billion in 2015, the ContiTech division, uses its expertise for products and systems made of rubber, plastic, metal, textile, and electronic components to combine these with individual services. Extremely flexible and high-temperature hose Applying its engineering expertise on hose technologies, for example, ContiTech has been able to develop an extremely flexible hightemperature hose ‘Conti Excelsus’ with external reinforcement for truck and off-highway applications. Its flexibility allows it to be used even in especially tight and complex installation situations – and that includes the very high temperatures encountered there. Depending on the particular finish, the hose can withstand temperatures of up to 250 °C. This makes it ideal for use in extremely hot environments. It can also withstand operating pressures of up to 15 bar. It supplies the turbocharger with cooling water and lubricating oil, and is also used in its control system. The hose is also suitable for transporting air in the exhaust systems such as a diesel particulate filter or as a fuel return line. ContiTech’s new development gets its flexibility from a special braid made of a various new and highly sophisticated textile materials which is resistant to high temperatures and chemicals. This encloses the inner lining made of rubber especially adapted for the application which is highly stretchable. The tight bending radii which are possible as a result are an ideal response to the trend towards downsizing in engines and the associated ever tighter installation spaces. As a result of its rigorously lightweight design, this cost-optimized solution also offers a significant weight advantage over the traditional PTFE pipes enclosed in a stainless-steel braid used hitherto for these tasks. The new hose therefore contributes to reducing fuel consumption and thus also CO 2 emissions. Another advantage for the customer is that it is part of a modular package from which the user can select the right product for the particular application. This yields further cost benefits for him. Advanced telematics for off-highway vehicles Thanks to a new telematics solution, fleet managers, drivers, and maintenance teams are always informed about relevant tyre-related data.
