Molex Debuts Next Generation MobliquA™ Bandwidth Enhancing Antenna Technologies

Molex Incorporated has released details about their development of innovative new technologies for antennas. The MobliquA™ antenna technology incorporates proprietary bandwidth enhancing technologies, which have been used successfully in Molex standard and custom antenna designs. The MobliquA technology is designed to improve impedance bandwidth in any application with a wireless interface antenna, including mobile phones, smart phones, portable TVs, and standard antennas in industrial applications.

“Traditional passive antenna structures are based on meandered antenna patterns, with limitations on manufacturing tolerances and mechanical properties. The MobliquA technology enables simple mechanical and robust antenna designs that minimize efforts needed for iterative retuning during each build cycle,” explains Morten Christensen, RF research manager, Molex.

Suitable for small cell phones, portable electronics, tablet and laptop-sized devices, the MobliquA technology offers a strong multi-use platform supporting both single and dual feed RF architectures within the same antenna structure. The dual feed configuration can provide at least 20dB isolation between the input ports, while maintaining the bandwidth-enhancing features. The good isolation and bandwidth simplifies optimization of antenna impedances to match different RF engines, which reduces current consumption and improves power transfer efficiency.

MobliquA technology provides a high degree of immunity towards insertion of metal objects into the antenna volume. Additionally, it enables utilization of RF decoupled or grounded parts, such as a grounded connector housing, as an integrated component of the antenna system. Furthermore, the technology provides excellent ESD protection of the front end due to its unique feeding techniques combined with a direct grounding of the antenna elements.

“Compared to standard systems, such as L or F type antennas, this new technology can provide impedance bandwidth improvements of 60 to 70 percent without increasing the antenna volume or compromising the radiation efficiency,” adds Christensen.

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.
