Rectangular connectors serve as essential interface components in a wide range of electrical and electronic systems, enabling high-density transmission of power and signals across diverse industrial, aerospace, and defense platforms. To ensure reliable operation in these demanding environments, many rectangular connectors are designed with rigid geometry, modular layouts, and secure mating features that are intended to enhance mechanical integrity and simplify system integration. In this blog, we will examine common connector types, key construction materials, and maintenance considerations that can influence performance over time, so read on to learn more.

Ram Air Turbines (RATs) are emergency systems that, when deployed by an aircraft, use the force of the airstream to rotate a small propeller which creates electrical or hydraulic power. This emergency backup system offers flight controls the hydraulic power and electricity they need in case of engine loss. When both engines are lost and the electrical supply to the main busbars is cut off, the RAT will deploy in order to provide hydraulic power to the emergency electrical generator (EMER GEN).

Commercial aircraft rely heavily upon electrical systems to power flight instruments, entertainment services, and other operationally necessary components. This electrical system is supported by batteries, engine-driven alternators, and auxiliary power units, as well as external sources while not in flight. Like everything else in aviation, the electrical elements in modern aircraft are chosen carefully to optimize safety and performance, while also achieving industry standardization. One aspect of aircraft electrical systems that is markedly different from other industries is the use of 400 Hz power. In this blog, we will discuss the rationale behind the 400 Hz standard, while also describing alternator components in detail.
