FANUC CRX-5iA vs DENSO COBOTTA PRO 900: 5–6 kg Cobot Comparison
Updated: 12 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE This is a load-versus-reach trade-off: DENSO COBOTTA PRO 900 has the higher stated load capacity, while FANUC CRX-5iA has the longer stated reach. Start with the constraint your task actually has. |
→ CONSIDER FANUC CRX-5iA Consider it when reaching farther matters more than the higher payload of the alternative. This article compares 5 kg with a published reach of 994 mm; include the gripper and part in the load. |
→ CONSIDER DENSO COBOTTA PRO 900 Consider it when additional load capacity matters more than extra reach. This article compares 6 kg with a published reach of 900 mm; include the gripper and part in the load. |
💡 THE TAKEAWAY Check the real tool, movement path and safety assessment before choosing. A collaborative label does not make every task safe without guarding; compare complete installation quotes. |
The FANUC CRX-5iA and the DENSO COBOTTA PRO 900 both repeat to ±0.03 mm. The COBOTTA PRO 900 carries 6 kg, 1 kg more, and is listed about 19% lower. The CRX-5iA is 4 kg lighter and rated IP67.
Quick verdict. The DENSO COBOTTA PRO 900 is the better value for fast collaborative assembly in dry cells, with 6 kg and a listed price $8,200 lower. The FANUC CRX-5iA is the better choice for coolant-exposed tending, a lighter arm and FANUC plants.
