What Exactly Do Air Coils Do?

An air coil is a special type of electromagnetic coil that is able to cause induction without using any ferromagnetic material. At the center of the coil is literally just a pocket of air. This is why it is also sometimes referred to as an “air core coil”. Because they are capable of handling such high frequencies, air coils are used for applications like microwaves where their high tolerance is still very important. Many military and aerospace devices also utilize air coil technology because the inductance caused by air coils is not disrupted by changes in the current.

Coils that are made with ferromagnetic coils tend to reach a peak even a moderate magnetic field strengths. In contrast, air coils have a very high range and can accommodate greater strengths. Most radios rely on air coils to help them transmit a clear signal. Air coils are also totally unaffected by “iron losses”. Iron losses affect ferromagnetic coils to a higher and higher degree as the frequency rises, so eliminating these all together with an air coil increases efficiency and limits distortion.

Due to the absence of a high permeability core, air coils are made with larger turns to facilitate the right inductance value. This isn’t really a problem at all when you are dealing with high frequencies, because you don’t need inductance in those situations. To limit any loss of energy that is caused due to presence of nearby electromagnetic radiation, air coils can be wrapped in a screen that provides protection.

Inductors in Radio Equipment

The name “inductor” is just another term from an electrical coil. An inductor has two terminals and it passively resists changes in the electric current. The inductor stores energy in the magnetic field while the current is being applied. Voltage is induced only when the current passing through the inductor changes. Most inductors are built with a magnetic core that helps to increase the magnetic field and enamel coated wire is wrapped around the core to increase the magnetism. Inductors of varying sizes are used in a wide variety of common electrical applications, including radios. Inductors in radio equipment allow for an alternating current that is free from interference.

The inductors that are used in radio equipment are extremely small; sometimes they are only a few millimeters across and consist of a few small turns of wire. Because a radio is essentially an AC (alternating current) application, an inductor is necessary to make sure that the device reacts properly to AC signals of different frequencies. Without this small component, the radio would not be able to handle all of the variations in the incoming frequencies and it would be totally useless. As mobile electronic devices that use radio frequencies have become smaller and smaller, engineers have had to find ways to develop even smaller inductors. Some inductors are now just a fraction of a millimeter in length, making them small enough to be integrated into a circuit board without taking up the limited space in a mobile device.

At Sag Harbor Industries, we specialize in manufacturing inductors for a wide variety of products and applications. If the inductor you need doesn’t already exist in our line of products, we can work with you to create a custom inductor. Our design and engineering team is capable of creating a perfect customized solution for your needs. Once we’ve come up with a working prototype, we will put an optimized manufacturing process in place to make your custom inductors as efficiently as possible. We do all of this because we want to put our customers first by being flexible enough to meet their needs. That’s the Sag Harbor advantage.

Why You Need High Voltage Coils

Electromagnetic coils carry an electrical current from point A to point B to create a reaction that activates a device. Depending on the power source, the voltage that is passing through the coil can vary greatly. In some applications, like a car’s ignition system, the voltage is very high. To control and conduct this electricity, the system needs high voltage coils that are capable of safely using the energy. At Sag Harbor industries, we manufacture high voltage coils that are perfectly suited to your application. We can even work with your product engineers to develop a customized coil setup that works with your new product.

When it comes to working with electricity, safety should be at the top of everyone’s priority list. Too many preventable accidents take place every year because of poor electrical engineering or the use of components that cannot handle high volumes of electrical current. When you work with the experts at Sag Harbor, you’ll find that we take our manufacturing approach very seriously to produce quality products that operate efficiently in under any conditions.

As we mentioned above, high voltage coils can be found in the ignition system of a car. The coil helps to convert voltage from the car battery into sparks that are produced by the spark plugs to ignite the engine when the driver turns the key. The ignition coil is usually encased in epoxy or oil to help insulate and contain the high voltage that passes through when the battery is activated. Ignition coils are made to be strong and durable, not only to withstand the high voltage that passes through them, but also to continue working in the harsh conditions of a vehicle in any weather. A high voltage ignition coil is subject to heat, extreme cold, moisture, corrosion and a host of other variables.

Sag Harbor Industries manufacturers high voltage coils for clients in the automotive industry, as well as many other industries with high voltage power sources. Contact us today to learn how our expert engineers and technicians can create a customized coil setup for your product, or how one of our standard products could be used in your business.

Sag Harbor Industries - Coils

Coils are used in many electromagnetic, electromechanical and electrical applications that are needed in almost every industry you can imagine. From clocks to cars to medical equipment, coils are an essential part of many complex or simple items that we use on a daily basis.

An electromagnetic coil is formed when a conductive metal is wrapped around a core to create electromagnetic waves. This is necessary in situations where electrical currents interact with magnetic fields, like in a transformer on a power line. The shape of the coil increases the strength of the electromagnetic field when a current passes through it.

An electromechanical coil, perhaps known more commonly as a solenoid, uses a similar process. The purpose of the solenoid is to create a controlled magnetic field. The coil in a solenoid is usually wound around a steel or iron core. The level of control made possible by a solenoid can be very useful at short ranges because of its very quick response time. Fuel injectors in a car, for example, are usually controlled by solenoid so that they can turn on or off based on the demands made by the person driving the car. As soon as the ignition is turned to the ON positon, the fuel injectors need to be activated to send fuel to the engine, and they need to stop the moment the ignition is turned off again.

Electrical coils use all of the principles discussed above, but they are the most basic form of a coil. They can be made out of various kinds of metal based on their conductivity needs, and can be found in common units like household appliances.

The coils that are manufactured at Sag Harbor Industries are sold to clients in many lines of work. Our coils are all made right here in the USA, and we offer solutions for every possible type of application, from solenoid to electrical to molded coils and more! We even manufacture self-supported coils that can be used in irregular or uncommon applications. Because Sag Harbor Industries has been a trusted manufacturer of coils for 70 years, we are known for the quality and high level of performance that comes with each of our products.

Transformers: Making Things Work

The more electronics grow and evolve, the more frustrating they become to some people. Mostly due to the fact that there are so many different electronics to own and know how to use. From finding the compatible remote to turn on the Blu-ray player to knowing the right channel the game is on out of literally thousands of options, electronics can be a difficult thing to master.

One other complication that comes with a number of different electronic devices is that many of them require a different voltage level in order to function properly and safely. Nowadays most products come with their own transformers that manipulate the voltage from an outlet into the acceptable voltage that the product needs. Other times, a separate adapter must be purchased in order for all different products to work from the same outlet. Transformers work by taking electrical energy and from one electric circuit and then sending it to another without changing the frequency.

Now as technology advances and we see more and more electrical devices, a lot of manufacturers and companies are making their products a bit more user friendly by including transformers with their devices. If you happy to purchase a product or industrial machine that requires a transformer, be sure to check in with us to figure out which transformer is best suited for your unique application.
