HOW TO ADAPT INTERCONNECTS TO HARSH ENVIRONMENTS SANDRINE HERMANT, PROJECT MARKETING MANAGER, AXON’ CABLE CHRISTOPHE TISSERAND, SALES MANAGER, AXON’ CABLE
When it comes to specifying the links or connectors used in a harsh environment application, knowledge of the constraints surrounding the application is necessary to propose the best possible technological solution. Interconnects already on the market generally have limited performance in terms of temperature resistance or electrical characteristics. Optimizing these solutions for harsh environments becomes a vital and necessary step. OPTIMIZING ETHERNET LINKS Ethernet cable assemblies are typically insulated with low-temperature thermoplastics (80°C) and
terminated with RJ45 connectors. Their quality is sufficient for traditional IT networks including Local Area Networks. To use the Ethernet protocol for challenging applications, including onboard devices for avionics or defense equipment, components must be optimized in terms of several characteristics. Weight savings and reliability are especially important considerations in the design of cables and connectors used in these environments. Depending on the application, resistance to high temperatures up to 150°C may be requested, which may require the incorporation of insulating materials into the cable.
