Development of the Compact, High Withstand Voltage "NU Series", Screw Terminal-type Aluminum Electrolytic Capacitors Guaranteed to Operate at 105°C

Nichicon Corporation, has recently developed the NU series of screw terminal-type aluminum electrolytic capacitors that will be used mainly in high voltage inverter circuits for power electronics and various industrial machinery. They are compact, have a high withstand voltage, and are guaranteed to operate at +105°C . They will go into mass production starting in October. The line-up will be on display at the CEATEC JAPAN 2012 exhibition to be held at Makuhari Messe from 2–6 October (Tues-Sat).

As systems require increasingly higher voltage due to advances in efficiency and energy saving features of machinery in the industrial sector, demand is also growing for screw terminal-type capacitors used in control circuits of inverter power sources to withstand high rated voltages of 500V or more, and have longer life. In response to the rise in withstand voltages, advances in miniaturization and longer life of such control circuits, we developed the compact, high withstand voltage NU series; screw terminal-type aluminum electrolytic capacitors guaranteed to operate at +105°C . Given the fact that there is a particularly high demand for products with high withstand voltages in the fields of solar and wind power generation and other fields relating to renewable energy, the NU series will also offer specifications optimized to these needs.

The NU series not only utilizes highly reliable electrode films with high withstand voltage oxide films, but it also has long term stability, electrolytic solution with enhanced film restoring capacity at high voltages, and low density, high withstand voltage, electrolysis paper. It also has a structure to enhance heat dissipation giving the series greater ability to withstand high voltages and a longer life compared to the current screw terminal-type NT series guaranteed to operate at +105°C .

Regarding products with a rated voltage of 500V, the new series is approximately 20 to 30% smaller than the NT series, and it will contribute to the miniaturization and weight reduction of devices.

Furthermore, in response to large load fluctuations in industrial machinery, we implemented our unique, highly appraised rapid charge-discharge technology to achieve high reliability, enabling the capacitors to be used, for example, in AC servo motors that require repeated rapid charging and discharging over short periods of time.

Finally, we believe that the enhancement of the ability to withstand high voltages will enable the capacitors to be used extensively for stabilizing power sources for machinery in regions with poor voltage and power source conditions in which the input voltage fluctuates.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications.
