Cable failure in moving machine axes is one of the top causes of unplanned downtime in automated production. Repeated bending, oil exposure, and electromagnetic interference chew through standard cables within months — replacing them means stopping the line, pulling apart drag chains, and losing valuable hours.This imported 10-core shielded drag chain cable is built to solve exactly that. It combines 8 signal cores (0.2 sq mm) for encoder and sensor feeds with 2 power cores (0.5 sq mm) in a single jacket — reducing cable count inside the drag chain by up to 40%. The overall braid shield blocks EMI from VFDs and servo drives. Tested to 10 million cycles in continuous flexing, it handles the kind of repetitive motion that kills ordinary cables.Core Parameters

Why This Cable Outlasts Standard Options
- Single-jacket design cuts drag chain fill. Running signal and power in one cable instead of two reduces bend radius stress and frees up chain space — critical on tight-radius arms and 6th-axis rotaries.
- PUR jacket resists the three killers: oil, coolant, and abrasion. In CNC machining centers where cutting fluid splashes constantly, PVC jackets swell and crack within weeks. PUR stays flexible and intact — even after prolonged oil immersion at 80°C.
- Braid shield + twisted pair signal cores handle VFD noise. Servo drives generate heavy electromagnetic interference. The ≥85% coverage braid, paired with individually twisted signal pairs, keeps encoder feedback clean — no position drift, no false faults.
- Pre-assembled with molded connectors available. M12, M23, or customer-specified connectors can be fitted at the factory. This eliminates field termination errors and cuts installation time by roughly half.
