E51424 - CAT 5e Ethernet Cable (Quadraxial)

The E51426 is a 100 Base-T Quadrax cable specially designed for airborne applications as defined by ARINC Specification 664. The overall design of E51426 allows a smaller overall diameter and weight while exceeding Category 5e requirements. The E51426’s construction of high-strength copper alloy conductors is surrounded by fluoropolymer insulation assuring uniform conductivity with excellent solderability. E51426 is designed to be terminated with ARINC 600 and D38999 quadrax contacts and is compatible with any contact designed for Tensolite cable part number NF26Q100. The 90% inner braid and 85% outer braided shielding provide double shielding to preserve technical performance. An ETFE laser markable jacket protects the cable against abrasion and environmental effects while maintaining flexibility for ease of installation.
