Electromagnetic interference (EMI) can significantly affect the functioning of a wide variety of products and disrupt the lives of those who depend on them. In such environments as a hospital or the military, this can even have far-reaching consequences. Numerous sources, including computer circuits, nearby electronic devices, power lines and even switches can cause this interference. EMI shielding is effective in preventing these radiations from interfering with devices and even stops the cross talk within the circuit of a particular device.. Traditionally, these protective solutions were made of metal sheets. Constructed with steel, copper or aluminum, these shielding products offer robust protection against electromagnetic disturbances. However, they are very prone to deformation. The fault lies in their design, which emphasizes making the enclosure extremely snug in order to prevent EMI leakage. This creates excessive mechanical pressure, and under this pressure, the metal EMI shields tend to deform. Then, some metals are more susceptible to oxidation and rusting. Elastomer products can overcome these shielding challenges. Here are three major benefits of these sophisticated shielding products:

Improved Efficiency of EMI Shielding Gaskets

Made of different types of polymers and blended with metal fillers, new generation elastomer products ensure superior EMI shielding. They also ensure a long performance life for the gaskets. An important thing to consider when selecting a conductive elastomer as an EMI shielding or environment seal gasket is galvanic compatibility. When you use two dissimilar materials, one of them tend to oxidize and fail to provide effective shielding in the long-run. The right gasket will offer the protection while undergoing minimum galvanic corrosion. Silicone shielding elastomers, that combine the properties of silicone rubber and metals, is often a good choice.

Feature-packed

Apart from increasing gasket efficiency, elastomer helps tone down the compression that builds up within the gaskets. This in turn improves air circulation inside the gasket. You can customize elastomeric products cost-effectively to meet the needs of specific production environments. As a result, you can find corrosion-resistant and flame-resistant products in the market. Apart from being robust and corrosion-resistant, these products are high on aesthetic appeal.

Efficient Shielding of Military Electronics

Militaries across the globe rely on technologies to gain an edge over their enemies. From anticipating enemy tactics to responding to their attacks, they rely heavily on a host of electronic devices such as radios, sensors, cameras and unmanned tactical weapons. However, these devices are particularly susceptible to electronic jamming or intentional EMI, a threat that endanger the lives of those fighting it out on the battlegrounds. Elastomer shields offer guaranteed protection against such intrusions.

When it comes to protecting your applications from EMI disturbances elastomer products can help you achieve correct shielding effectiveness. While selecting a product, the first thing you need to consider is the appropriate shape or type of gasket. The next important criteria relates to the polymer material.

Different elastomer products are made of different types of polymers such as Silicone, Fluorosilicone and Ethylene Propylene Diene Monomer (EPDM). Each one works in specific kind of environments. The types of environment your products will interact with will determine the type of polymer that you should opt for.

All About Custom Cable Assemblies

Published / by mimin

Custom cable assemblies are generally comprised of several different parts, including the actual wire, a jacketing portion to shield the wire and possibly necessary insulators or conductors. It seems rather straightforward, but it can become quite confusing when considering the many different types of wiring options available. Of the many varieties existing on the market today, there are five generally common types of cables. They differ based on function and durability, as well as the materials of which they are comprised.

Heliax Cables

A heliax cable is a type of coaxial cable arrangement. In a coax cable, there are three layers within a jacket, beginning with a sold core inner conductor. This inner conductor is surrounded by insulation. In a heliax configuration, the insulation is wound in a helix, or a spiral, around the conductor. It has a semi-rigid composition, but performs quite well. Unfortunately, the rigidity of the wire makes this custom cable assembly limited in its uses.

Molded Cable Assembly

A molded cable structure is a method for creating the system you need. Generally, molding introduces the use of hard shield connectors within a cable system to maintain continuity. Often, these are pin-like in their formation. Molded cables can prevent the exposure and failure of wires to the outside elements. This custom cable assembly is ideal for different situations in which protection against the environment is essential.

Mast Cables

A mast cable is used mainly for radio and communication systems. It is set up as a tall mast, or stick, in the air. A sleeve protects a mast custom cable assembly; it is usually vinyl in nature, and it keeps the wires within safe from environmental elements, like sunshine and rain. Mast systems generally have great structural integrity and can be used for a variety of functions but are most often seen on ships, in military installations, and on top of radio towers.

Sensor Cables

Sensor cable structures have experienced some break-through technology recently, as more researches are coming together to study possible uses and exciting evolution of its capabilities. Generally, a sensor is based on magnetometers that are incorporated within a jacket or shield. These types of custom cable assemblies can be used above or below ground and report any physical disturbances through vibrations and communicative symbols.

Ribbon Cable

A ribbon wire is a flat, wide piece of cable that, of course, resembles a ribbon. They are generally used for transmitting data and are often found within computer systems. An interesting component to ribbon cable is that very frequently, ribbon cable is color-coded to avoid incorrectly identifying individual conductors. These are optimal for tight-spaces, as ribbon cable is easily pliable.

Step Audiophile For Beginners

There are many situations when one is listening to music where outside or ambient noise can be heard. This proves to be distracting and takes away from the listening experience. That is why the purpose of active and passive noise cancelling headphones is to cancel out ambient noise. Hi-fi listeners actively seek to cancel out ambient noise in order to improve their listening experience. In this article, we talk about the two main methods this is achieved when listening with headphones.

Active noise canceling headphones require batteries or some sort of charging in order to function properly. How it works is that the headphones have a mic and that mic is used to pick up the sounds around you. As it picks up the surrounding sounds, a processor takes the sounds and fires back the same frequencies 180 degrees out of phase. In theory, this should cancel out the incoming sound. But as all things go in the real world, it does not work out perfectly. This technology works well when having to cancel out low and constant frequencies, such as the engine of a plane, but when it comes to the dynamic sounds of your ambient surroundings and other high frequencies, it does not do so well.

Many active noise cancelling headphones come at a premium price with a lower quality sound. Not only that, most of them don’t even seem to work! This is because companies use marketing tactics such as “15 dB reduction” or “95% noise cancelling” which can technically be true because decibels are worked on a logarithmic scale! That does not go to say that ALL of them don’t work. There are very high quality active noise canceling headphones out there in the market, like the Bose QuietComfort, however they are extremely expensive.

The alternative is to buy regular headphones or earphones in that matter, to passively cancel out noise. How this basically works is by designing headphones and earphones in a way to best block out incoming ambient sounds through material construction and using no other electronics. That being said, closed back headphones and to a certain extent, open back headphones, all provide this passive noise cancellation. Depending on which headphones you buy, you get a different level of passive noise cancellation. That being said, you may never be able to 100% cancel out noise, but when you buy a pair of cans that fit well and crank that volume up, it can really isolate you from the rest of the world.

Earphones do a much better job at passively canceling out noise because they mold into your ear canal and effectively block out any other noise from coming in while blasting sound waves directly to your ear. This is why many performers use monitor earphones to guide their performances when they are singing.

In conclusion, whether you decide to go with active noise canceling or passive noise cancelling, we again encourage you to tryout your options before investing in them. From our own experiences, we feel that a solid pair of closed-back headphones or earphones get the job done and there is really no need to get fancy with the active noise cancelling headphones, but we leave that choice to our readers.
