The YK1200XG is a SCARA robot designed for the assembly and transport of large and heavy objects. It features a 1200mm reach and achieves industry-leading cycle times with a maximum payload of 50kg. The RCX341 dedicated controller, while maintaining the compact design of the previous RCX340, increases the maximum output current, providing support for the high-speed transport of heavy loads by the YK1200XG.The YK-XG series SCARA robots are characterized by their beltless structure. The direct connection of the end rotational axis to the reducer allows for high permissible inertia on the R-axis, enabling high-speed operation even with offset workpieces.
