EMC Performance Classification: EMC rating scale (VDE/EN standards): Basic: No shielding (part 813 unscreened) Fair: Partial coverage, 30–40 mm spacing in braid Good: 80–90% coverage, 95% coverage, all gaps 30 dB attenuation @ 500 kHz: >40 dB attenuation @ 5 MHz: >35 dB attenuation (typical peak range) Expected: Tinned copper braid achieves 35–50 dB across frequency range Immunity to external interference: Motor variable frequency drive (VFD) nearby: VFD RF emission: Typically 50–200 mV/m at cable distance Unshielded cable susceptibility: 100–500 mV induced noise Shielded cable (good EMC): 1–10 mV induced noise (50–100× reduction) Consequence: VFD-driven crane motor doesn't interfere with control signals No false triggering of safety systems Data integrity in digital control systems maintained Radiated immunity testing (per EN 61000-4-3): Test standard: Cable exposed to RF field 50 MHz–1 GHz Test field strength: 10 V/m typical Acceptance: No malfunction, signal corruption
