E20424 - CAT 5e Ethernet Cable (2 Data Pair)

The E20424 is a 2 pair, 10/100 Base-T CAT5e cable specially designed for airborne applications as defined by ARINC Specification 664. The overall design of E20424 allows a smaller overall diameter and weight while retaining performance and required operating parameters. The E20424’s twisted-pair construction (two separate pairs) of silver-plated copper conductors is surrounded by dual-layer foamed/solid fluoropolymer dielectric that assures uniform conductivity with excellent solderability. Removal of the outer foamed layer reveals the inner solid insulation of a diameter compatible with conventional RJ45 connector terminations. The 100% foil (for each pair, as well as the entire cable) and 90% braided shielding assure uniform conductivity with excellent solderability, further protecting against EMI*. An FEP jacket protects the cable against abrasion and environmental effects while maintaining flexibility for ease of installation.

*The individual pair foil shields are also isolated from the overall foil shield for additional protection.
