EFK Feedback-CP Screened PUR Drag Chain Feedback Cable is a flexible cable for encoder and resolver feedback links between servo motors and controllers. The cable uses polypropylene insulation, a tinned copper braid screen and a green polyurethane outer sheath to support dependable signal connections in machine tools and drag chains with medium mechanical stress.
Applications
Use EFK Feedback-CP for servo feedback circuits in machine tools, automated production equipment and cable carrier systems where a screened connection cable is required. The construction is suitable for indoor and outdoor installations with a maximum moving distance of 100 m. For your required core layout, Request a Quote from TEBAOFLEX.
