If you thought that the NEMA ratings are just meant for NEMA power cords, you might be wrong. The NEMA association also has ratings for electrical enclosures. Electrical enclosures are nothing but the cabinets or boxes in which we mount switches and knobs for the electrical products to work right. Through these ratings, you can define the type of environment in which electrical enclosures can withstand themselves. NEMA undertakes strict testing requirements to check if the enclosure is protective against dust, oil immersion, water, external ice etc. All the NEMA ratings come with different specifications and these ratings help to protect property, personnel as well as electrical components from damage. The Significance of NEMA Ratings Just like you check your NEMA power cable with its ratings, it is important for you to check the ratings of the enclosure before mounting it. And why is it important? Well, there are 3 important reasons behind it. 1. These ratings enable th...

After the release of HDMI 1.4, the new HDMI 2.0 standard was released. It brought along several changes and enhancement with the specification. However, for those who are wondering what changes have come in after HDMI 1.4, we have come up with certain features and specifications. So, here we go about understanding them: Things you must know about HDMI 2 Improved Frame Rates and Full 4K Support The framerate of HDMI version 1.4 was up to 30 frames per second at high resolution. As and when the TV industry started asking for 4K Ultra HD resolutions support, the need for HDMI support also increased. This is when 2.0 version came to the rescue. It supports 4K resolutions up to 60 frames every second. Now this, is a drastic improvement. When it comes to movies, frame rates are of less important as there are 24 frames per second. But it offers great resolutions to content like video games and media streaming. Hardware Support – No New Cables Required As HDMI 2.0 offers the en...

For all those who are unaware, “NEMA” is an abbreviation of National Electrical Manufacturer’s Association. It is an association of electrical equipment and medical imaging manufacturers and its mission is to build and promote safe electrical standards as well as products. If a plug is labelled “NEMA”, you can consider it to be an industry standard for safety. NEMA offers a wide array of plugs. But when it comes to lighting fixtures for industrial and commercial purposes, there are several confusions as to which type of NEMA power Cord should be used for what purpose.The basic functionality of these power plugs is to ensure proper connection for different electrical equipment and curb the risk of accidents. This article will acquaint you with the most commonly used NEMA power plugs which connect lighting fixtures to the receptacles. These power plugs are covered by ANSI/NEMA WD-6 standard which is set by National Electrical Manufacturers Association, abbreviated as NEMA. Specif...

HDMI , also known as High Definition Multimedia Interface is an advanced technology that is used for transmitting digital data between two digital devices. This technology was developed by leading electronics manufacturers like Philips, Toshiba, Hitachi, Sony etc. Ever since it was introduced, it has become quite popular. Its latest version, 2.0, was introduced in September 2013. If you are new to HDMI Cables or HDMI adapters and want to know more about it, take a look at some frequently asked question and their answers. These will give you more insights about HDMI cables and their working. What is the purpose of HDMI technology? HDMI technology is mostly utilized to transmit multichannel audio and high definition video data between two digital devices. This process of transmission takes place through a single cable. You will be able to find HDMI technology in all the latest electronic equipment including AV receivers, personal computers, set top boxes and camcorders. How do...

You might not have a great chemistry with electronics. But in your day to day lives, you are sure to have come across long wires that power local area networks. These are known as Ethernet Cables. When it comes to LAN technologies, Ethernet technology stands out to be the fastest and the most popular one. Through this blog, we will acquaint you with the ins and outs of Ethernet technology and how it came into being. History and Evolution of Ethernet Technology Over the years, Ethernet technology has evolved a lot. New versions of these Cables have come up. And customers have bought several off the shelf cables for different purposes. Now, let us peek into the history of this technology. In the year 1972, two engineers, namely D.R. Boggs and Bob Metcalfe developed Ethernet. Based on their work, industry standards were set under the IEEE 802.3 set of specifications. The specifications provide manufacturers with technical details and low-level data transmission protocols. It enable...

Any adapter, connector or cable that is used to change female connectors to male connectors and vice versa is known as a gender changer.

Digital Signal Processing is the process of transmission and production of data that takes place without any interference. This process asks for an Ethernet Cable. Most of the wired networks of today including routers, PCs and switches use Ethernet cables for the smooth transmission of data. These Ethernet Cables are of two types – Shielded and Unshielded. They are also known as STP (Shielded Twisted Pair) and UTP (Unshielded Twisted Pair). The question that arises next is - which one out of the two you should buy? To find this out, make sure you know about the environment you need Ethernet cables for. One of the major reasons behind networks slowing down is - voltage interference. Hence, you must make sure that the electrical line intersects with low voltage communication cable at 90 degrees. Given below are some other factors you should consider before buying shielded or unshielded Ethernet cables. Alien CrossTalk The antenna of Ethernet cables are like the cross-section. D...
