Slip Ring-Free Cable Spool for Easy Cable Management


Perfect for industrial robot users, the e-spool flex 2.0 cable reel with no slip ring allows for easy management of robot teach pendants while supplying bus signals without interruptions. The reel can extend cables up to 50 ft and is flexible, movable, and easily stowed. Installation into a robot’s control center is simple with the included mounting hardware.


The e-spool flex 2.0 is igus’ version of a cable drum without a slip ring. The cable is safely routed through a feed-through to ensure that it is always properly wound. Cable diameters of 5 to 15 mm can be used. The unit can be installed on the floor, ceiling or wall and safely guides media power, data or air in one system. The space-saving design includes a locking mechanism on the cable and is adaptable to technological developments by simply replacing the used cable. The design is also cost-effective in case of repair as it allows for the replacement of individual components.


Other features include a snail mechanism that allows for uninterrupted cable connection and easy insertion of existing cable even when connectors are already attached. The system also has high-transmission reliability and various winding variants. The reel can be used whenever a cable must be moved freely during use and must be stowed away safely and cleanly after use.
