unassailable ‘fit & forget’ pressure moulded cable systems for hostile environments

Aerospace Connector And Cable Solutions

Aerospace technology is constantly evolving to deliver more efficient and capable aircraft. This creates demand for light-weight, high performance bandwidth and interconnection that is able to withstand harsh and hostile high-altitude operating environments.

Scientific Management International designs and manufactures connector and cabling solutions that form an aircraft’s central nervous system, delivering data, power and control across systems, regardless of altitude or operating conditions, while reducing platform weight.

High performance and reliable aerospace systems

Materials we use in our aerospace solutions accommodate thermal expansion and contraction during changes in altitude, meaning SMI products will never fail on critical systems. Additionally, our solutions are designed to resist mechanical stress, corrosion damage, lightning strike, and biological or chemical contamination.

With our fit and forget approach to aerospace solutions, complex service and replacement programmes are not required, greatly reducing through life costs.
