Global EMC Shielding Market Expected to Grow

 

According to new research, the switch from wired to wireless technology and the “emergence of a number of directive and regulations in favor of EMC shielding solutions drive the EMC shielding market.” Alternatively, the smaller scale of devices coupled with their complexity and high cost is said to slow the growth of the market. For revenue generation, Asia has the highest … [Read more...]

Electric Potential: EMI Shielding in Electric Vehicle Applications

 

The growing challenge of preventing electromagnetic interference (EMI) is particularly acute in the automotive sector. Cars feature increasing numbers of electronic systems, often in close proximity because of packaging constraints. Information systems such as GPS receivers, entertainment systems such as DVD players, and convenience features such as reversing aid cameras all … [Read more...]

Expand Safe I/O with Modular Safety Controller

 

Phoenix Contact’s new modular safety controller makes it easy to expand I/O in a safety circuit. The PSR-TRISAFE/M (for modular) connects up to 10 safe digital I/O modules, thanks to a T-bus system. The TRISAFE/M’s base station has 20 safety input signals and four safety category 4 outputs. It also provides outputs for a test pulse, alarm (aux), and ground switching. The safe … [Read more...]

Designing Electronic Systems for EMC: Grounding for the Control of EMI

 

There are two primary reasons for grounding devices, cables, equipment, and systems. The first reason is to prevent shock and fire hazards in the event that an equipment frame or housing develops a high voltage due to lightning or an accidental breakdown of wiring or components. The second reason is to reduce EMI effects resulting from electromagnetic fields, common impedance, … [Read more...]
