Drag chain cables in high-speed CNC machines and robotic arms fail fast — insulation cracks, conductors break, EMI kills sensor signals. Downtime from cable replacement eats into every production hour. The FD 855CP solves this.This is a German-manufactured 4-core 1.5 mm² shielded drag chain cable, built with PUR polyurethane outer jacket and tinned copper braid shielding. Designed for continuous reciprocating motion in energy chains, it handles mechanical stress, oil, coolant, and electrical noise — all at once.Core Specifications

Why FD 855CP Holds Up Where Standard Cables Don’t
- PUR jacket resists cutting fluids, hydraulic oil, and coolant splashes — common in machining centers and stamping presses. Unlike PVC, it does not harden or crack after prolonged oil exposure.
- Rated for over 10 million bending cycles at rated radius. In 600 mm travel robot arms running 24/7, that translates to years of service before inspection.
- Copper braid shield blocks EMI from VFDs and servo drives — critical when signal and power share the same cable run in compact drag chains. No extra foil layer needed.
- German production with consistent wall thickness and concentric lay — reduces snagging inside energy chains and prevents uneven wear that leads to early jacket failure.
