EFK Feedback-CP(i) Screened PUR Drag Chain Feedback Cable is a flexible encoder and resolver connection cable for servo controller feedback circuits in machine tools and drag chain systems. It combines extra-fine stranded copper conductors, TPE insulation, a tinned copper braid screen and an orange polyurethane outer sheath for dependable signal transmission under medium mechanical stress.
Applications
EFK Feedback-CP(i) is suitable for encoder and resolver connections between servo motors and controllers where repeated movement, compact routing and electromagnetic protection are required. It is designed for indoor and outdoor machine applications with a maximum moving distance of 100 m. For a confirmed configuration, Request a Quote from TEBAOFLEX.
