A relay is a type of switch controlled by a circuit. Essentially, relays send messages telling a machine to start. For example, when a car is started, the ignition only indirectly interacts with the car battery, because a relay is sending the signal that tells the car to start. Relays are necessary parts for many electrical devices because they require less power to be used than many of the devices they are connected to. Using a car battery as an example again, if the battery were connected directly to the car’s ignition, it would require a great deal of power and wiring to start the car. With a relay, a far smaller amount is needed, because it is only a mediator. In addition to saving energy, this is a much safer way of starting the car than having a great deal of wiring and electrical power.
Optoelectronics is a field that concerns itself with the study and use of electronic systems and devices that are capable of producing, governing, and detecting light. As a sub-field of photonics, optoelectronics encompasses light such as visible light, X-rays, ultraviolet, infrared, gamma rays, and more. As a technology, optoelectronic devices serve a wide variety of applications and are constantly expanding as a field of study in the modern era. In this blog, we will provide an overview of the various types of optoelectronics, as well as some various examples of devices belonging to them.
Power Entry Modules (PEM) are electromechanical components that are implemented within appliances and systems in order to integrate the appliance inlet with other components. In general, these components include switches, circuit breakers, fuse holders, voltage selectors, appliance outlets, and more. Power entry modules may be used to simplify the assembly process, or they may be used to benefit the product design.
Electromechanical systems that are systems and apparatuses that are used to transform electrical energy into mechanical movement, as well as the other way around. Typical examples of electromechanical systems are solenoids and electric motors, and they may be found in a variety of industries and applications to provide actuation or movement. Such systems may cater to a number of applications, providing for devices such as electromechanical panel controls or electromechanical switches. In general, there are four major types of electromechanical systems, and these include motors and gearboxes, DC generators, shape memory alloy actuators, and linear actuators.
Turbine engines are favored for the many advantages that they have over reciprocating engines, such as an increased aviation performance, less vibration, and better reliability. There are many different types of turbine engines in the aviation market. They are classified based on their compressor and on whether or not they have axial flow, centrifugal flow or a combination of both. They can also be classified based on the flow that the air takes through the engine and how that power is produced. There are only four ways in which this flow can happen and you can find out more about that by learning about the four different types of turbine engines, which are the turbojet, turboprop, turbofan and turboshaft.
The function of an analog input, also known as an AI or AIN, is to convert voltage levels of an item into a digital value that can be processed and stored inside of a computer. An AO or analog output, on the other hand, does the opposite in that it converts the digital value from a computer into a voltage level that is presented on an output terminal so as to provide an adjustable output.
A board stacking connector, sometimes known as a board to board connector or simply PCB connector, is an item that provides a foundation, housing, and terminals for printed circuit boards. Manufacturers in the industry will use board stacking connectors because it enables them to utilize more than one printed circuit board while simultaneously keeping them organized and condensed. By stacking the printed circuit boards on top of one another, you can save space inside of your computer or wherever else you are placing your printed circuit boards
Transformers are electrical devices that allow an AC input signal (like audio) to produce a related AC output signal without the input and output being physically connected. This phenomenon is called inductive coupling. Inductive coupling occurs by having two or more coils of insulated wire wound around a magnetic metal core. These wire coils are called windings. When an AC input passes through the input winding (the primary), a related AC out signal appears on the output winding (the secondary). This wireless magnetic field communication is preferred over expensive and inefficient downtimes of physical connectors that wear down quickly due to mating and de-mating. In this article, we will focus on transformers designed for audio.
With the debut of GPS for the consumer and business market, the technology has seen tremendous growth in its use and applications. From smartphones to vehicles, GPS services are often just a click away and can provide life saving information. Within marine equipment, GPS can now help increase safety and navigation while traversing the open waters. As the years go by, technology for marine navigation is constantly improving as well. In this blog, we will give a short overview of the various types of GPS and navigational systems that can be used for vessels.
In any electric circuit breaker, resistors play a key role in managing the flow of electricity. Sometimes however, an electrical engineer only wants to limit certain amounts of current, rather than a blanket level. In these cases, the designers or engineers will install a varistor, a voltage-dependent resistor. A portmanteau of “variable resistor,” a varistor’s resistance decreases as the voltage flowing through it increases. In the case of an excessive voltage increase, their resistance drops dramatically, making them very useful serving as transient voltage suppression, which can be caused by natural phenomena like lightning strikes and electrostatic discharges.
