Head to head
FANUC SR-6iA vs Omron i4
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Fast SCARA for assembly and packaging lines
Compact SCARA for light assembly and packaging
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the FANUC SR-6iA carries more, 6 kg to the Omron i4's 5 kg. They run different controllers, the FANUC SR-6iA on the R-30iB Compact Plus and the Omron i4 on the Built-in internal controller, so whichever platform your team already programs and stocks parts for is a real tiebreaker. For a tight or overhead cell, the FANUC SR-6iA lists Floor mounting while the Omron i4 lists Table mounting, which the other does not. Both are aimed at assembly and packaging, with the FANUC SR-6iA stretching to machine tending.
- High-speed planar motion for pick-and-place
- Tight repeatability for small parts assembly
- Compact footprint for dense cell layouts
- Shares programming with FANUC six-axis lines
- Very compact for dense bench cells
- Tight repeatability for small-parts assembly
- Integrates with Omron vision and PLC systems
- Low mass simplifies mounting
