PUR Shielded Servo Cable 4×2.5mm² + 2×(2×1.0mm²) | Power + Screened Feedback

PUR shielded servo cable 4×2.5mm² power + 2×(2×1.0mm²) individually screened feedback pairs. 0.6/1kV power, 300V signal. Class 6. For medium servo motors with brake and encoder feedback.

PUR Servo Cable — 4×2.5 mm² Power + 2×(2×1.0 mm²) Screened Feedback

This medium-duty servo motor cable is designed for servo motors in the 1.5–7.5 kW range where 2.5 mm² power conductors are required, combined with two individually screened feedback pairs for encoder and brake signals. The 1.0 mm² feedback conductors provide lower resistance than 0.5 mm² pairs — beneficial for long cable runs where brake coil voltage drop must be minimised, and for encoder supply lines where supply accuracy affects encoder performance.

The two independently screened pairs allow the brake control pair and the encoder pair to each have their own dedicated screen — preventing brake switching transients from coupling into the encoder signal pair.


Key Design Features

  • Power: 4×2.5 mm² (3-phase + PE), Class 6 fine-stranded Cu
  • Feedback: 2×(2×1.0 mm²) — two individually foil-screened pairs
  • Each feedback pair: drain wire for individual shield termination
  • Overall tinned copper braid ≥85%
  • PUR outer sheath — oil, coolant, flex rated
  • Rated voltage: 0.6/1 kV (power); 300V (signal)
  • Drag chain flex: −40°C to +80°C
  • Min bending radius (flex): 7.5×OD
