Seifert thermoelectric enclosure coolers from AutomationDirect beat the heat

Automation-Direct has added new high-quality and efficient stainless steel Seifert 340 BTU/H thermoelectric coolers with 120-V and 230-V power options. Thermoelectric coolers from Seifert use the Peltier Effect to create a temperature difference between the internal and ambient heat sinks, making internal air cooler while dissipating heat into the external environment. Fans assist the convective heat transfer from the heat sinks, which are optimized for maximum flow.

Free-Core vs. Spring-Loaded LVDT position sensors

Linear Variable Differential Transformers are electro-mechanical devices used in many industrial applications to measure the displacement or position of an object. They convert the linear position or motion of a measured object into an electrical output that is displayed on a local readout or input into a programmable logic controller as part of an automated process control system. LVDTs come in two core configurations -- free-core and spring-loaded -- but do you know what the differences are?

New enclosure heat exchanger options

Automation-Direct has added new Saginaw Enviro-Therm^® air-to-air heat exchangers that use an enclosure's ambient air and either heat pipes or aluminum plate to transfer heat from inside the enclosure to the external environment. Since the ambient air is the cooling medium, the need for refrigerant is eliminated. Features include corrosion-resistant internal components, a filterless design for maximum cooling and reduced clogging, simple installation, and a programmable digital controller.

World's smallest-width floating connector simplifies automotive installation

Hirose has developed a space-saving, board-to-board connector that combines floating functionality and miniature size to meet automotive specifications. The BM54 Series boasts the world's smallest-width class for its category, a 0.4-mm pitch, and a stacking height of 3.0 to 4.5 mm. This connector is ideal for PCBs with multiple connector sets and offers a wide floating range of +/- 0.4 mm in the XY direction. By absorbing board misalignment errors, floating simplifies assembly and improves assembly work efficiency. Applications include cameras, displays, millimeter wave radar, and LiDAR systems.

Touchless angle sensors get CAN SAE J1939 interface

Novotechnik has added the CAN J1939 interface (developed for heavy-duty vehicles) to its RFC4800 Series of touchless angle sensors measuring angular position up to 360°, turn direction, turns, speed, and operational status. It can provide one or two output channels. It has a longer life and robustness than an optical encoder. It can signal if a sensor needs replacing or average a programmable number of values to output to reduce external noise if present. This is wear-free angle measurement made easy.

DARPA brings next-gen U.S. microelectronics manufacturing closer to reality

The Next-Generation Microelectronics Manufacturing program, known as NGMM, aims to unlock accessible prototyping for the chips of tomorrow with a new agreement to establish the first-ever national center for advancing U.S.-based microelectronics manufacturing.

The Defense Advanced Research Projects Agency (DARPA) will work with the University of Texas at Austin and its existing Texas Institute for Electronics research center to establish a consortium to support 3D heterogeneous integration (3DHI) microsystems research, development, and low-volume production. Building on the program's Phase 0 foundational research, NGMM's next two phases focus on a domestic capability that comprehensively addresses key challenges and strengthens U.S. technological leadership and innovation.

"We're holistically addressing tomorrow's challenges and solutions. That starts with an onshore, open-access center for 3DHI microsystems prototyping and pilot line manufacturing," said Dr. Whitney Mason, director of DARPA's Microsystems Technology Office. "This accessibility to researchers from academia, government, and industry will break down silos and foster an ecosystem that enhances the U.S. competitive advantage."

The consortium will leverage partnerships spanning organizations across the defense industrial base, domestic foundries, vendors and startups, designers and manufacturers, members of academia, and other stakeholders to achieve a shared vision of national and economic security.

DARPA's work in microelectronics R&D align with, but are separate from, broader government initiatives to secure microchip supply chains. NGMM is funded by the Defense Department (DOD) budget, rather than the CHIPS and Science Act of 2022 aimed at near-term domestic semiconductor manufacturing. However, cross-collaboration remains integral to building onshore capacity. For DOD, that includes programmatic investment in over-the-horizon technologies for both national security and commercial applications -- a key goal for NGMM.

"We can't overstate the need for constant and unwavering forward momentum in microelectronics capabilities. The CHIPS Act's near-term emphasis can help reinforce NGMM's work toward realizing the next major wave of microelectronics innovation," Mason said. "Supply chain resilience and reducing overseas reliance requires working together as a community, with both traditional and non-traditional members. That's what this program is about."
