Signal cables in moving machinery fail fast. Repeated bending cracks insulation, EMI from servo drives corrupts data, and unplanned downtime costs more than the cable itself. If your control signals drop out every few months inside a drag chain or cable carrier, the problem is usually the cable — not the system.This imported 12-core signal control cable is built for exactly that environment. Each conductor is 0.1mm² (28AWG) tinned copper, twisted in pairs to cancel noise. An overall foil shield plus tinned copper braid blocks EMI from VFDs, inverters, and welders. The jacket is a special PVC compound rated for continuous flex in drag chains — tested to over 10 million cycles at tight bend radii.Core Specifications

Why This Cable Lasts Longer in Tough Applications
- Tinned copper resists oxidation inside the chain. In humid shops or outdoor gantries, bare copper turns green and resistance climbs. Tin plating keeps contact stable even after years in a cable carrier.
- Twisted-pair layout cuts crosstalk between 12 cores. When you run encoder, sensor, and I/O signals side by side in one jacket, untwisted cores bleed into each other. The controlled twist pitch (≤40mm) keeps signal integrity clean up to 100m runs.
- Dual-layer shield handles real-world EMI. A single foil shield is not enough next to a 7.5kW servo. The braid layer underneath gives a low-impedance path to ground — measured shielding effectiveness >60dB at 1MHz.
- Jacket compound is formulated for chain drag, not just flex. Standard PVC hardens after 500k cycles in a carrier. This compound stays supple past 10 million cycles at 1.5m/s chain speed — verified in-house on Igus and Kabelschlepp test rigs.
