Coficab COFDATA 100 JSTP ETH 125-4 Shielded Automotive Ethernet Cable, 2 x 0.50mm² The larger-gauge sibling to the COFDATA 125-3, this shielded multi-core data cable is built for in-vehicle Ethernet applications demanding a heavier conductor cross-section, while retaining the same shielding and thermal performance. Why choose this cable: • 100 ± 5 Ω characteristic impedance, built to Open Alliance 1000BASE-T1 requirements • ≥ 50 dB shielding attenuation for strong EMI/RFI protection • Wide operating range: -40°C to 125°C (3,000h), thermal overload tolerance to 155°C • Tinned copper conductor (CU ETP1, EN 13602), 19 x 0.19mm stranding per core for added flexibility • TPE-S outer jacket in BK_GN-WH color configuration for easy harness identification • Supplied on D600 reels, 1,200m standard content Ideal for: automotive and commercial vehicle Ethernet backbones, ADAS and infotainment data links, and applications needing a larger-gauge conductor than the 125-3 for longer runs or higher current-carrying needs.
