Updated: 11 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE This is a load-versus-reach trade-off: DENSO VM-6083 has the higher stated load capacity, while FANUC M-20iD/12L has the longer stated reach. Start with the constraint your task actually has. |
→ CONSIDER FANUC M-20iD/12L Consider it when reaching farther matters more than the higher payload of the alternative. This article compares 12 kg with a published reach of 2272 mm; include the gripper and part in the load. |
→ CONSIDER DENSO VM-6083 Consider it when additional load capacity matters more than extra reach. This article compares 13 kg with a published reach of 1,021 mm; include the gripper and part in the load. |
💡 THE TAKEAWAY Choose the robot that handles your actual tool and part through the required path, with controls and support your team can use. Compare complete installation quotes, rather than arm-only prices. |
