Nextreme Achieves New Milestone in Cooling Performance for Thin-Film Thermoelectrics

Nextreme Thermal Solutions, the leader in micro-scale thermal management and power generation solutions, today announced that its thin-film thermoelectric technology has achieved a 60.1°C temperature difference between its cold and hot sides at an ambient temperature of 24.7°C, bringing it on par with the performance of bulk thermoelectric technology. The 60°C temperature milestone, known as the ΔTmax, reflects the ability of the thermoelectric device to pump heat efficiently. This new level of performance translates to improved cooling efficiency, lower input power requirements, and greater opportunities for solving thermal issues in electronics, photonics, automotive, avionics, and high-speed PCR applications.

The electronic industry’s continued trend of smaller form factors, greater circuit density, and highly integrated packaging has translated into significant thermal problems for electronics-related manufacturers. As a result of this technology achievement, Nextreme can now bring its thermal management solutions to additional, substantial markets that require not only the current advantages of its products, but also the performance provided by this new capability. This provides Nextreme the opportunity for significant business growth over time.

The improved performance is the result of new materials development at Nextreme and the use of advanced, state-of-the-art interconnect and contact technology developed at the Center for Solid State Energetics at RTI International.

“Our thin-film technology has now achieved the performance level of standard bulk thermoelectrics,” said Dave Koester, vice president of engineering at Nextreme. “Achieving a 60°C ΔT at room temperature raises the bar for improved efficiencies and lower operating costs for our customers while opening up new markets for Nextreme.”

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.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
