Energy chain / drag chain
Extruded inner PVC bedding supports the tinned copper braid against wire breakage over 5 million carrier cycles.
Product
EMC-screened continuous-flex control cable featuring IEC 60228 Class 6 copper conductors, extruded PVC inner bedding, ≥ 85 % optical coverage tinned copper braid and oil-resistant TM5 PVC outer jacket for electrically noisy machine-tool carriers.
Typical values for this cable type, based on DIN VDE 0285-525-2-51 / UL AWM 2570 — confirmed in the datasheet and quotation for your order.
Application fit
Engineered for linear energy chains where PLC analogue/digital control lines run alongside VFD motor leads and require 360° EMC screening.
Extruded inner PVC bedding supports the tinned copper braid against wire breakage over 5 million carrier cycles.
Direct routing on machine frames and inside cabinets with 360° EMC gland termination.
Suitable for indoor C-rail festoons requiring shielded control and interlock circuits.
Suitable for auxiliary small AC drives up to 2.5 mm²; use low-capacitance PP/PUR cable for main servo motors.
Use Shielded Servo Motor Power CableNot intended for high-tension outdoor crane drums; use screened rubber reeling cable.
