Application fit
CF211.PUR Shielded Feeder Encoder Cable featuring stranded copper twisted pairs (4×2) and subsea / marine outer protective sheath (UL AWM 20233 / VDE 0812, 300 V, -40 to +80 °C, min. bend radius 7.5 × OD).
Short-pitch Class 6 copper stranding and low-adhesion TPE/PUR jackets deliver multi-million-cycle life in horizontal and self-supporting d
Robotic torsion (RF-Torsion) and coiled spiral builds absorb ±180°/m to ±360°/m multi-axis twist on ROV pan-and-tilt and manipulator wrist
Hydrolysis-, seawater-, fish-oil- and UV-resistant outer jackets operate reliably above open fish tanks and coastal feed tracks.
High-coverage tinned copper braided screens protect encoder, load-cell and servo signals from VFD interference.
Drag-chain and robotic wrist cables are not designed for high-tension deep-ocean vertical lift winches.
