Overview

The SpaceNXT™ QT series is part of Smiths Interconnect’s overarching initiative entailing the creation of a full range of higher reliability products for next generation space applications that are readily available on the market. All products have passed design verification and are rigorously tested per customer and industry application requirements. SpaceNXT™ QT series assemblies are manufactured with low loss fluoropolymer dielectrics and constructed with materials which meet the outgassing requirements of NASA/ESA when tested per ASTM E595.

The outer jackets use ETFE material for increased radiation resistance. SpaceNXT™ 065QT, 100QT, and 160QT cables are specifically designed for space flight applications on LEO, MEO, and GEO satellite platforms and offered with standardized testing sequences, reducing delivery times and overall cost of ownership.
