As one of the leading manufacturers of components, systems and solutions for electrical engineering and automation, Eaton’s Electrical Sector or is launching new DC-Switch-Disconnectors. The constantly growing requirements placed on the efficiency of PV installations require operating voltages above the previously usual limits of 1000 VDC. Eaton has consequently further developed its proven DC switch-disconnector product series. Switches for up to 1500V DC with rated operational currents up to 1600A are now available. Switches and accessories are now suitable for ambient temperatures up to 65°C. Typical applications for example are switch-disconnectors in generator terminal boxes, as well as isolating main switches that are suitable for use as maintenance and repair switches on the incoming side of the DC/AC inverter.
Balluff introduces BPS, a newly developed series of pressure sensors with IP 67 protection for use in gaseous and liquid media. The rugged devices feature a high-quality, long-term stable ceramic load cell and an especially attractive price/performance ratio, simple installation, high operating comfort and high preci-sion. A large, bright and easily visible display ensures immediate status overview. This shows not only the current system pressure in bar, mbar, PSI and MPa, but also features fast and simple configuration of the sensors according to the VDMA standard, using 2 keys and intuitive menu guidance.
Technifor can offer an electromagnetic micropercussion marking solution for use on all materials. The micro-impacts produced on the material surface using a carbide tipped stylus create a lasting mark, without creating stress or chippings. This new machine is the result of the process to optimise the Technifor range, adding a powerful electromagnet combined with an optimal guide system to produce marking of remarkable precision and quality.
The performance density of industrial gearboxes has been increasing with more compact designs and higher requirements. NKE AUSTRIA offers a wide range of bearing solutions for the increasingly demanding applications. In addition to cylindrical roller bearings, the typical gearbox bearings include spherical roller and tapered roller bearings as well as angular contact and deep groove ball bearings. Special bearings manufactured according to customer specifications can also be supplied. NKE’s gearbox bearings are used, for example, in general mechanical engineering, in mining and conveying systems, in heavy machinery, in the iron and steel industry and in wind turbines.
The new Anybus® Wireless Bridge from HMS is a solution for extending industrial Ethernet networks with wireless communication. The solution makes it possible to connect industrial devices running Profinet, EtherNet/IP and Modbus TCP, over a wireless connection.
As one of the leading manufacturers of components and systems for electro- and automation technology, Eaton's Electrical Sector offers high switching powers at 690VAC, with its new NZML2 and NZML3 circuit breakers. With the new NZML2 and NZML3, special highlights are being brought to market at the 2011 Hannover Messe. Both enhance the already-existing, world-renowned NZM family and round off the assortment in the area of systems with high energy density. Not only do industries such as mining, ship applications or the chemical industry require high switching powers of 690VAC, renewable energies such as wind energy systems, for example, are also a target of the new products.
Wireless is utilized now more than ever in control architectures. It is flexible, versatile and can be cost effective; however, concerns with the security, reliability, and capacity of wireless continue to prevent conservative end users from reaping its benefits. Are these concerns valid? This article will address these points head-on, disentangling the misconceptions from genuine challenges, providing insight about how to overcome obstacles now and down the road with proper understanding, planning and execution.
