Keeping emitting sources and radiating paths under control with EMI Shielding Tape

December 17, 2018

Keeping emitting sources and radiating paths under control with EMI Shielding TapeIn simple terms, radiated EMI emission starts from an emitting source, propagates via a radiating path and reaches a susceptible receiver. The strength of the radiated EMI is determined by the source, the media surrounding the source and the distance between the source and the susceptor1…unless there are cables in close proximity to the source or receptor, in which case all bets are off. In that case you need EMI shielding tape. Electronic or electrical cables can compound EMI noise problems as they are major transmitter of stray signals. Unshielded cables can act as a conductor, sending direct disruption to sensitive ... Read more

MAJRabsorber™ : The Latest Innovation in RF Absorber Material and Changing How we Think About What is Possible

November 7, 2018

MAJRabsorber™ : The Latest Innovation in RF Absorber Material and Changing How we Think About What is PossibleEvery once in awhile true innovation transforms an industry.  Consider what the cloud has meant for business as it brought about data storage, access and co-worker collaboration.  Look at how the Internet of Things is frontiering cashierless shopping. Such champions in innovation will not only make the industry and applications they integrate with faster, easier or better, they change the way we think about what’s possible.  Over time these disruptors soon become the new industry standard and we wonder how we lived without them before their introduction. For the EMI/RFI shielding industry, this transformative shift is now taking place in ... Read more

Conductive Elastomers: Silicone vs. Fluorosilicone
Will Your Hardened Enclosure Remain Effective in Harsh Environments?

September 19, 2018

Conductive Silicones are often an essential component for hardened boxes and enclosures where environmental sealing and EMI/RFI shielding is required. The typical silicone-based gaskets and seals are impregnated with nickel, silver, copper, aluminum or other conductive particles to give non-conductive silicone their conductivity while providing IP rated environmental sealing that is required in many military electronic applications. These Conductive Silicone materials are also very flexible and can be formed into sheets, extrusions in various profiles, strips, washers and custom molded parts to fit almost any specific requirement, regardless of how unique. But the one issue with these essential conductive silicone ... Read more

Custom EMI Ventilation Panels: An End to the “Square Peg – Round Hole” EMI Shielding Dilemma

August 15, 2018

Hardened enclosures come in all shapes and sizes.  When you compound the possibilities of various applications, industries, specifications and regulatory authorities, it’s no wonder that standard sizes, types or material for shielding a hardened enclosure rarely meet specific needs for any given project.  Even though most hardened enclosures are custom designed with specific requirements in mind they often have one thing in common: They all must breathe to allow cooling of sensitive electronic equipment while also being protecting from EMI/RFI. Up until now this has been an ongoing problem for engineers.  Rarely are enclosures designed to be able to use standardized ... Read more

EMI/RFI Wire Mesh Grounding and Conductive Elastomer Washers: Hardened Enclosure Shielding in Small Places

July 19, 2018

EMI/RFI Wire Mesh Grounding and Conductive Elastomer Washers: Hardened Enclosure Shielding in Small PlacesThe smallest details are often the ones that will determine whether an EMI hardened enclosure will be compliant or will not  meet EMC requirements. That’s especially true when it comes to the many bolts, screws, rods or shafts that need EMI/RFI shielding or grounding.  When you have to attenuate a signal or ground components of an enclosure, don’t forget the EMI/RFI wire mesh grounding or conductive washer. Here’s what you need to know: EMI/RFI Wire Mesh Grounding Washers EMI/RFI wire mesh grounding washers are made from wire mesh socks that look somewhat like thin knitted metal hoses before being compressed in a ...

Conductive Coatings for Plastic Hardened Enclosures: Getting the Job Done Quickly and Cost Effectively

June 20, 2018

Conductive Coatings for Plastic Hardened Enclosures: Getting the Job Done Quickly and Cost EffectivelyThere is no doubt that plastics have their design advantages when building many hardened enclosures. Plastics products in various forms, such as acrylics, ABS or structural foams, are quick and inexpensive to produce once tooling is in place and can be molded or configured in complex designs much more readily than some other substrates. But because plastics are electrical insulators which easily allow EMI or RFI waves to penetrate the substrate, conductive coatings, i.e. conductive paints, pick up the slack where plastic alone would allow failure of your hardened enclosure. It becomes imperative, therefore, to consider conductive coatings when using ... Read more

A Guide to EMI Shielded Ventilation Panels: Protecting Your 2nd Largest Area of Exposure in a Hardened Enclosures

June 1, 2018

A Guide to EMI Shielded Ventilation Panels: Protecting Your 2nd Largest Area of Exposure in a Hardened EnclosuresThink about the need for EMI shielded ventilation panels – what they do and why you need them.  Are you fully protecting that hardened enclosure with the right option?  Does it measure up to standards for your civilian or military application? EMI shielded vent panels are the understated hero of hardened enclosures.  Second only to an access panel or door in terms of size, ventilation panels can act like a giant antenna, inviting outside EMI or RFI signals in.  At the same time, passive and ambient air vents or fan ventilation panels can also form a major conduit which lets uncontained ...

EMP Shielding: The Background, Need and Solutions

May 21, 2018

EMP Shielding:  The Background, Need and Solutions Definitions & Distinctions HEMP is defined as an instantaneous, intense electromagnetic pulse (EMP) field that can overlaod and disrupt from great distances electrical systems and microcircuits. It is generally assumed if one occurred it would be set off by a high altitude nuclear explosion; obtainable by missle flight1 or, more recnetly believed, from a satellite. The only real defense for an event is with HEMP shielding. IEMI is defined as an intentional malicious generation of electromagnetic energy introducing noise or signals into electric and electronic systems, thereby disrupting, confusing or damaging the systems for the purpose of criminal or terrorist activities2. It ... Read more
