AWG24 100 Ω Aerospace Ethernet Cables in Stock

Application : Within modern avionics architectures (ATA 23 , Communications, ATA 25, Equipment/Furnishings, ATA 31, Indicating/Recording Systems, onboard 100Base-TX Ethernet networks form the backbone of IFE systems, Cabin Management Systems (CMS), cabin servers, avionics LRUs, and data gateways.

Strict control of 100 Ω differential impedance, NEXT, SRL, LCL, attenuation, transfer impedance, EMC/EMI performance, and compliance with FAR 25 / EN 3375 / ABD0031 is mandatory.

Air Cost Control, a specialized distributor of certified aerospace cables, maintains immediately available stock of two strategic references:

  • ABS 1503 KD 24  
  • KL24 Series – EN 3375-011  

Objective: Secure MRO supply chains, cabin retrofit programs, and OEM production by reducing lead times and mitigating AOG risk. 

ABS 1503 KD 24 : Shielded Quad Aerospace Ethernet Cable 

The ABS 1503 KD 24 is a high-speed data transmission cable designed for 100 Mbit/s Ethernet networks and In-Flight Entertainment applications.

Electrical Architecture & Materials 

  • Characteristic impedance: 100 ± 15 Ω (1–100 MHz)
  • Conductors: AWG24 – 19 x 0.13 mm stranded silver-plated copper
  • Primary insulation: FEP (high-temperature fluoropolymer)
  • Construction: Shielded quad (4 cores + FEP filler)
  • Shielding: 0.10 mm silver-plated copper braid
  • Outer jacket: Light blue FEP, UV laser-markable

The shielded star-quad configuration optimizes:

  • Differential symmetry
  • Capacitive coupling reduction
  • Crosstalk control (NEXT)
  • EMC robustness in high-EMI density environments (radars, SATCOM, power converters)
