MAJR Products Ventilator Systems & Medical EMC Shielding

May 19, 2020

Ventilator Systems & Medical EMC Shielding Medical facilities are one of the epicenters of the Covid-19 pandemic. Their capacity to treat infected patients with life-saving equipment like medical respirators is vital. Severe Covid-19 patients can develop a  life-threatening condition called acute respiratory distress syndrome (ARDS) that requires ventilators to deliver smaller volumes of oxygen and air at high rates. From the very beginning of the pandemic, hospitals understood the severe implications of ARDS on a predicted onslaught of lung impacted patients and turned to the medical device industry for additional machines and support. Companies like MAJR Products, whose shielding products are critical ...

How to Use Our EMI/RFI Shielding Design Flow Chart

April 13, 2020

Once you’ve determined that your systems or components need isolation from surrounding electromagnetic fields, or to block the transmission of additional signals, designing the appropriate enclosure is crucial.  Our shielding design flow chart can help designers and engineers navigate the varied types of EMI/RFI shielding materials available to choose the right materials that meet your specific shielding and environmental requirements.    From Table 1, first identify the intended environment: indoor, outdoor, or both. Next, select the NEMA or IP enclosure type: commercial, military, marine, land or desert. Or for indoor applications, warehouse or office. IP RATINGS IP ratings classify the degrees of protection against the ingress ...

EMI/RFI Shielding For Medical Device Applications

March 16, 2020

EMI / RFI Shielding For Medical Device Applications Take any average-sized hospital in the U.S. and count the number of electronic devices in use. According to the World Health Organization (WHO), that number averages over 10,000. Imagine all those separate life-saving devices – magnetic resonance imaging (MRI), computed tomography (CT or CAT), Electromyography (EMG) and others working side-by-side without interference. Unfortunately, many of these devices have non-conductive, plastic components that don’t shield Electromagnetic Interference/Radio Frequency Interference (EMI/RFI) from being emitted from or penetrating to other devices. They require shielding systems incorporated into the design and manufacture, ensuring reliable performance. According to medical device engineers, due to their design and ...

HEMP Danger Requires EMP Shielding

February 12, 2020

Fortunately, the chance of a direct military attack on America from a foreign country is very slim. However, as we’ve seen from 9/11 and other terrorist attacks on our soil, the chance of a smaller and more terroristic threat is still very real. One of those types of attack is from a High-Altitude Electromagnetic Pulse (HEMP), which is the dispersal of a nuclear explosion of electromagnetic energy produced in the atmosphere by the power and radiation of a nuclear explosion, whose damage to electronic equipment would be felt over a very wide area. According to the U.S. Congressional Research Service: “Several nations, including reported sponsors of terrorism, ...

TEMPEST, SCIF, and Electronic Shielded Enclosures

October 8, 2019

For systems to be certified to TEMPEST (Telecommunications Electronics Material Protected from Emanating Spurious Transmissions) specific test standards need to be passed such as NSA No. 94-106 for shielded enclosures and other NSA standards depending on the intended environment and operation. The TEMPEST certified telecommunications electronic enclosure needs to be a “Faraday Cage”. A Faraday Cage is an enclosure made of electrically conductive materials capable of blocking magnetic and electric fields, commonly known as the electromagnetic field, see Figure #1. Figure 1 – Electric and Magnetic Field(courtesy of HyperPhysics) Figure 2 – Shielded Electronic Enclosures(courtesy of Milium Textiles and Vertex Structures) Figure 3 ...

EMI Gaskets: Die-Cut, Water Jet & Flash Cutting

August 26, 2019

EMI gaskets are used in a variety of electronic devices where EMI/RFI is an issue including communications, military electronics, and RF applications. When it comes to manufacturing EMI gaskets, there are three different methods MAJR Products uses: 1. Die-Cut 2. Water Jet 3. Flash Cutting Each of these three manufacturing techniques have specific benefits associated with them and are best suited for a plethora of different products and materials including: Conductive materials Rubber Cork Foils Silicones Neoprenes Porons Thermal Materials Tapes Thin Films Mylar Kapton 1. Die-Cut Die-cutting is a high-speed method of using a die to shear webs of low-strength materials in order to mass produce a wide range of industrial products, including gaskets. MAJR creates a predesigned ...
