E51428 - CAT 5e Ethernet Cable (Quadraxial)

The E51428 is a 100 Base-T Quadrax cable specially designed for airborne applications as defined by ARINC Specification 664. The overall design of E51428 allows a smaller overall diameter and weight while exceeding Category 5e requirements. The E51428’s construction of silver-plated high-strength copper alloy conductors is surrounded by a solid PFA insulation assuring uniform conductivity with excellent solderability. The 80% braided shielding provides shielding to preserve technical performance. A PTFE laser-markable jacket protects the cable against abrasion and environmental effects while maintaining flexibility for ease of installation.
