University Picks Building Site Because of Low EMI

 

University of Washington leaders recently broke ground on a molecular engineering building, the location of which was chosen partly because the natural vibration and electromagnetic interference are low at that site. Researchers will be making very sensitive measurements and any movement can interfere with the accuracy. The foundation will incorporate an extra-thick concrete … [Read more...]

Shielded Window Material Takes New Approach

 

Chomerics Europe, a division of Parker Hannifin, has introduced Winshield C, a shielded window display material. Winshield C is a cast monomer material that combines good physical properties with electromagnetic shielding performance and optical clarity. Applications include display filtering in test equipment, medical instrumentation, public information displays and military … [Read more...]

Nanotube Separation Wins Company New Contract

 

Bio Nano Consulting has signed its largest contract to date with an unnamed chemical company to develop a consistent system for the separation of single-walled carbon nanotubes based on their electrical properties. The work will develop the processes to a stage where the client can license and further commercialize the technology. Possible applications for metallic nanotubes … [Read more...]

EM Coating for Low Frequency Magnetic Shielding

 

Integran Technologies’ Nanovate EM coating for low frequency magnetic shielding achieves similar performance to specialty discrete magnetic shielding foils, but uses a process that allows a nanocrystalline metal to be applied directly to metal, polymer and composite substrates. The process flexibility enables applications where part size or complexity makes the use of formed … [Read more...]

New Book Focuses on EMI Shielding

 

A new book published recently by an EMI materials engineer focuses on the role that EMI shielding plays in EMC (Electromagnetic Compliance) design and reviews EMI shielding with emphasis on materials and designs across many industry applications. “Advanced Materials and Design for Electromagnetic Interference Shielding,” written by Dr. Xingcun Colin Tong, PhD, of Laird … [Read more...]

New Material for Low-Frequency Magnetic Shielding

 

MuFerro™ 6800 from Holland Shielding Systems B.V. is a new material for shielding the low frequency magnetic fields found in transformer rooms, power plants, and bus-bar systems. Although most magnetic fields are typically in the 50- to 60-Hz range, MuFerro provides magnetic shielding in the frequency ranges from 10 Hz to 100 kHz. This material can provide a field-strength … [Read more...]

Enclosures Cast in Lightweight Magnesium Alloy

 

Teko Enclosure Solutions’ latest hand-held enclosures are die-cast in ultra-lightweight magnesium alloy with absolute strength and high EMI/RFI shielding properties. The enclosures are sealed to IP 67 (NEMA 4X) protection class, include side profiles with soft-touch surface, have a top recess for membrane keypad or label and include three types of battery compartments and … [Read more...]

Airframe Tests Help Ensure Better Shielding for Flight Instruments

 

Airline travelers are used to being instructed to turn off computers and cell phones during takeoffs and landings as a precaution against interfering with the plane’s navigational equipment, but outside sources of high-energy interference can be even more dangerous. Recent tests by researchers at the National Institute of Standards and Technology will provide much needed, … [Read more...]

New Gasket Design for EMI Shielded Honeycomb Vents

 

Tech-Etch has introduced a new continuous integrated gasket for shielding honeycomb vents that offers better performance, reduced cost and the fastest production time. Continuous lengths of the high-performance BeCu gaskets are mechanically installed under the inner perimeter of the vent’s aluminum extrusion frame. No tooling is required to manufacture and attach the gasket to … [Read more...]
