Overview
EN 3375-012:2013 - Aerospace series: Cable, electrical, for digital data transmission - Part 012 - defines the product standard for a single-braid Star Quad shielded quad cable, Type KH (short designation: KH24). It specifies dimensions, materials, electrical and mechanical requirements for an AWG 24 quad cable designed for high‑speed 100 Mbit/s full‑duplex Ethernet use in aerospace environments with operating temperatures from −65 °C to 260 °C. The cable is laser markable in accordance with EN 3838 and has a characteristic impedance of (100 ± 15) Ω.
Key topics and requirements
- Construction & dimensions
- AWG 24 stranded conductor diameter 0.598–0.656 mm; outer cable diameter 4.35–4.55 mm; mass ≤ 45 g/m.
- Jacket colour: preferential light green; component pair colours: Pair 1 Red/Blue, Pair 2 Yellow/Green.
- Minimum bending radius: 10× outer diameter (dynamic), 5× (static).
- Materials
- Conductors and braid: nickel‑plated copper.
- Insulation, jacket and filler: fluoropolymer (high temperature resistance).
- Electrical performance
- Characteristic impedance: 100 ± 15 Ω (1 MHz–100 MHz).
- Maximum attenuation specified across frequencies (e.g., 17.3 dB/100 m at 31.25 MHz at 25 °C) with temperature adjustment rules.
- Capacitance ≤ 60 pF/m (1 kHz); velocity of propagation > 0.66 c at 31.25 MHz.
- Near End Cross‑Talk (NEXT) and transfer impedance limits defined (NEXT values and Zt max. in mΩ/m by frequency).
- Tests & quality
- Comprehensive electrical, mechanical and environmental tests referenced to EN 3475 series: thermal ageing, thermal shock, cold bend, bending, abrasion, strippability, laser markability, attenuation, NEXT, transfer impedance, etc.
- Quality assurance per EN 9133; marking and identification per EN 3375-002 and TR 6058.
