Limit switches are switches used to automatically detect the presence of an object or to monitor and indicate whether the movement limits of that object have been exceeded. Their original use, as the name suggests, was to define the limit or endpoint over which an object could travel before being stopped. Once the endpoint was reached, the switch would be engaged to control the limit of travel.

Despite the two terms often being used interchangeably, relays and contactors are different devices. A relay is a device used to control the contacts of an electrical circuit due to a change of parameters or conditions in the same circuit or another associated circuit. Contactors, adversely, are devices used to interrupt or establish connections in an electrical circuit repeatedly under different conditions. As both devices perform the task of switching a circuit, their definitions alone are not really enough to differentiate the two. In this blog, we will take a deeper look at the differences between relays and contactors.

A terminal block is a modular block with an insulated frame used to secure two or more wires together. Terminal blocks consist of a clamping component and a conducting strip. The insulated frame of a terminal block houses a current carrying element (either a metal strip or terminal bar) while providing a base for the clamping element. The body also features a mounting arrangement, allowing the block to be easily mounted on or unmounted from a printed circuit board or mounting rail. Most terminal blocks are modular and mounted on DIN rails, allowing the number of terminals to be increased.

Since the release of the Boeing 737 series back in 1967, the family of aircraft has remained the most popular and demanded series of all time, even to this day. Despite fierce competition and rising sales of the Airbus 320 family, Boeing still holds on to the title of most models produced and delivered for their orders, a title they most likely will continue hold for the foreseeable future. Even Boeing 737 parts remain in constant demand for outfitting the longstanding aircraft series. Back in 2013, Boeing stated that a 737 was taking off or landing every 2 seconds across the world, and currently the 737 model still makes up about 75% of Boeing’s production backlog. With so many different airliners and aircraft models competing for dominance in the Aviation Market, what is it about the Boeing 737 that keeps it so popular even to this day?

Because the market on aircraft maintenance tools is a very niche one, the prices for tools in the field are not always consistent across the board. Many manufacturers or retailers of such parts will feel at liberty to charge whatever outrageous price they can for things like a magnetic synchronizer, twist pliers, rivet guns, jacks, etc. And because it’s such a small market, consumers will often have to purchase these items at that price. But with enough knowledge of these products and also on those who are selling them, you can avoid paying such high prices on your parts. See the basic outline below on how to avoid paying more.

When you think of elevators, you probably don't picture the rear of an airplane. Although the elevator is a small piece of equipment relative to the rest of an aircraft, its role is crucial. An elevator is a fixed-wing aircraft component known as a flight control surface. A flight control surface maintains an aircraft’s pitch, angle of attack, and lift. It is typically at the rear of an aircraft where it attaches to the horizontal stabilizer on a plane’s empennage.The horizontal stabilizer and elevator are both factors in stabilizing the pitch, but only the elevators contribute to pitch control. The pitch is the tendency of the aircraft’s nose to move up and down on the lateral axis.

The landing gear of an aircraft supports the entire weight of a vehicle during landing and ground operations. The components are primarily attached to the actual structure of the aircraft and has different applications for each part. Wheels are most commonly associated with aircraft landing gear but, there are many other facets involved. Modern landing gear technology wouldn’t be possible if shock absorbing equipment didn’t exist, making shock absorption a crucial aspect of both landing and takeoff.

To maintain performance, aircraft require constant maintenance of their structural integrity. Metal structural repairs must be done with the best available techniques and materials, as deficiencies can pose an immediate or potential danger. This is complicated by the fact that an aircraft must be kept as light as possible, which narrows the margin of safety. This means that repairs must be strong enough to carry all the loads caused by flight, but not be so strong that they weigh the aircraft down. A joint that is too weak is obviously intolerable, but a joint that is too strong can end up causing stress and cracks in other locations.

Ice formation on aircraft has long been a hazard to commercial and The military aviation, as well as the private flyer. Besides affecting the safety and performance of aircraft, severe icing conditions have been the cause of a large number of flight interruptions. Ice formation on the wings, tail surfaces, and fuselage is responsible for an increase in weight and the loss of aerodynamic efficiency. Severe vibrations and loss in thrust may result from ice accumulation. During heavy ice conditions in which ice occurs on the propellers and the aircraft simultaneously, the plane may be unable to climb properly, or maintain altitude, causing an emergency landing. The issue of determining adequate and practical means of combating ice formation has brought deicing and anti-icing systems to the forefront in aircraft design. This blog will focus on bleed air technology, pitot tube heating, propeller ice prevention, and heated edges systems.

Structural integrity is an important concept in aviation. In fact, it’s probably the most important concept in aviation. So, you’d imagine that when it comes to things like fasteners, welding, which is a relatively reliable method of fastening, is preferable to rivets. But that’s not the case. Airplanes are manufactured with riveted joints instead of welded.

Ground Support Equipment plays important part in every ground support missions vary drastically between civilian and military operations. Although civilian operations have a set timeline of when an aircraft and its individual parts need to be serviced or repaired, it's not as strict of a timeline as the military. Military ground support also has the disadvantage of unpredictable working conditions that range from the limited or uneven pavement of a bare base to an entire airstrip at a well-kept airport. It is difficult to determine what could go wrong, but it is expected that all military ground support equipment items will work at all times, under all conditions.

We like to think of new and groundbreaking technology as being something like a new iPhone or a new Boeing commercial jetliner. But, actually, the biggest innovations usually come as a result of the smallest parts. Earlier in September, Anritsu Company, the United States subsidiary of Anritsu Corporation in Japan, introduced a new line of W1 coaxial components. This new family of metrology-grade designed and manufactured components are intended to remove measurement complexity, reduce setup time, and improve accuracy to deliver precision performance and repeatability for high-frequency measurements.
