EWIS Connectors: The Backbone of Modern Aviation
The aviation industry has undergone a remarkable transformation, driven by advancements in technology and an unwavering commitment to safety. Central to this evolution is the Electrical Wiring Interconnection System (EWIS), a critical component that ensures reliable power and signal transmission throughout aircraft.
EWIS connectors refer to Electrical Wiring Interconnection System connectors. These connectors are a part of the broader EWIS, which encompasses the components and wiring used for electrical interconnection in an aircraft. EWIS connectors are crucial for ensuring the integrity and reliability of electrical systems in aviation. They facilitate the transfer of electrical signals and power safely and efficiently across different parts of an aircraft.
The design and implementation of EWIS connectors are guided by stringent aviation standards to prevent electrical failures that could affect the safety and operation of the aircraft. They must endure various environmental conditions such as temperature fluctuations, vibrations, and mechanical stresses while maintaining performance and safety.
BonChip Electronics, as a leading distributor of electronic components, understands the critical role of EWIS connectors in the aerospace industry. Our extensive product portfolio, coupled with our expertise in the field, enables us to provide comprehensive solutions for aircraft manufacturers and integrators.
Understanding EWIS
EWIS represents a holistic approach to aircraft wiring design, encompassing connectors, cables, terminals, and related components. Introduced by the Federal Aviation Administration (FAA) in response to safety concerns, EWIS has become an industry standard, ensuring consistency and reliability in aircraft electrical systems.
The development of new aircraft concepts, such as electric vertical takeoff and landing (eVTOL) vehicles, has placed even greater emphasis on the importance of EWIS. These advanced aircraft require lightweight, compact, and high-performance connectors to meet the demands of complex electrical systems.
SOURIAU – SUNBANK Connection Technologies (available from TTI Inc. and ICC (Interstate Connecting Components)
has been working in partnership with different airframers, focusing on
products qualification to ensure a reliable use of components over their
expected lifetime. These qualifications are done either according to
airframers’ specifications.
Key Components of EWIS
EWIS connectors are at the heart of aircraft electrical systems, providing reliable and secure connections between various components. These connectors must meet stringent performance requirements, including:
- Durability: Ability to withstand harsh environmental conditions, including vibration, temperature extremes, and humidity.
- Reliability: Consistent performance over the entire lifespan of the aircraft.
- Weight and Size: Minimization of weight and size to optimize aircraft performance.
- Safety: Adherence to stringent safety standards to prevent electrical failures.
