Many electronic designs need shielding materials that combine resistance to electromagnetic interference (EMI) with other application-specific requirements. For example, the EMI gaskets that are used in military touchscreens need to attenuate EMI emissions, provide electrical conductivity, and ensure environmental sealing. These shielding gaskets also must also cushion the unit … [Read more...]
The Future of Shielding
THE FUTURE OF SHIELDING The future is not all that far off. With more electronic devices that are getting smaller, more portable and with continuing faster speeds, EMI or RF issues will continue to increase. There will be more integrated system-onchips (SoCs) where several functions will all be in one device that will need to be electromagnetically isolated. As an example, a … [Read more...]
SCHURTER Classic Power Entry Module with Circuit Breaker Gets Even Better
Santa Rosa, California, November 30th, 2023 – SCHURTER series DG11 and DG12 with and without main filters feature a first-of-its-kind ingress protection solution for IEC inlets, consisting of a seal gasket between the connector and mating V-Lock power cord. The blue colored latch of the V-Lock power cord and blue inlay of the appliance inlet indicate that the two have been … [Read more...]
Techniques For Mitigating Intrapair Skew-Induced EMI With Shielded Connectors
Introduction EMI stands for electromagnetic interference. There are several methods of EMI transmission from the source to the victim. Two of them are radiated EMI and conducted EMI. Radiated EMI happens when an electrical device produces an RF signal that is picked up and causes unwanted effects. Conducted EMI is unintentional energy carried out of the source via signal … [Read more...]
Connectivity for Off-Road Vehicles – Part 3
Zonal Architecture for Vehicles Zonal architecture is the name given for the new structure of vehicle electronics. In contrast to a traditional vehicle in which systems are grouped by function, zonal architecture offers a more efficient solution. The functions within a vehicle are grouped by location into several zones. Each zone is responsible for the devices that are … [Read more...]
Connectivity for Off-Road Vehicles – Part 2
The Future of Vehicle Design The next generation of vehicle design will be influenced by four key trends. The first is electrification – the adoption of hybrid and all-electric power as alternatives to traditional fossil fuels. The use of electric power by commercial vehicles has become commonplace in the urban environment, where operators have easy access to charging … [Read more...]
Connectivity for Off-Road Vehicles – Part 1
Introduction With over 1.4 billion cars worldwide, it is easy to assume that the only product of the automotive industry is the family car. However, the market for industrial, commercial, and agricultural vehicles is not only growing, but it is also embracing the latest technology. Even as these vehicles are becoming increasingly sophisticated, a significant number will … [Read more...]
A Beginner’s Guide to EMP Filters – Part 1
Introduction While many may be concerned by an outright nuclear attack on US soil, the emerging clear and present danger predicted by government and private think tanks is Electromagnetic Pulse (EMP) threats. Such a threat, carried out by strategically placed land devices, could be catastrophic to virtually every facet of our civilization. Organizations both public and … [Read more...]
Fundamental Oscilloscope Probes
As electronics have become more advanced, so has the equipment used to measure their signal behavior and system performance. In the realm of EMC compliance, oscilloscopes are one of the important tools used to measure signals, hunt down noise sources, and identify time-domain measurements that may contribute to radiated or conducted emissions. Without a properly selected probe, … [Read more...]
Radiated Emissions Testing
INTRODUCTION Radiated emissions testing is only one part of emissions testing. CISPR 32, the document that lays out limits and methods of measurement for emissions (radiated and conducted) for Information Technology Equipment (ITE), broadcast receivers and multimedia equipment is 120 pages in length. ANSI C63.4 deals with only the testing part (limits are contained in a … [Read more...]
