The FANUC M-20iB is designed for the environments that break other robots - it’s about keeping production running when dust, splash, debris, and grime are part of the job.
The FANUC M-20iB's enclosed design helps protect uptime in real-world conditions where standard robots struggle. FANUC sums up this new addition to their line-up, “Enhanced performance and enclosed construction for demanding environments.”
M20 platform evolution
M20iA + LR Mate = M20iB/25.
Compare the enclosed cables and motors in the M20iB/25 to the unenclosed
M20iA (left), where servo motors and cabling are exposed.
Key difference: exposed vs enclosed cable routing and motor protection.
Harsh-ready design
Sealed construction helps limit exposure to moisture, dust, and debris. Smooth surfaces and routing reduce buildup and cleanup effort.
Predictable throughput
Built to run steady shifts with fewer nuisance stops.
Precision and Reliability
Repeatability to +/-.06mm because of the new more rigid design.
Watch the M-20iB in action
Where the M-20iB really earns its keep
Washdown-adjacent packaging
Keeps pace near sanitation zones without constant attention.
Dusty or powder handling
Reduces buildup that causes early wear and downtime.
Machine tending
Helps protect components from chips and mist.
Design, ratings, and where the M20iB/25 fits best
The M20iB/25 features enclosed, integrated cables, motors, and arm construction, giving it an
IP67 rating on all six axes. This design makes the robot well suited for
environments where exposure to moisture, debris, or contaminants would quickly impact standard robots.
IP67 on all axes
Fully enclosed motors and cabling help protect the robot in wet, dirty, and harsh processes.
Special environments
Ideal for food handling, washdown-adjacent operations, and contamination-prone processes.
Food-grade option
A white food-grade / cleanroom version is available with the same specifications.
Design features that matter in real cells
Slim upper arm design that helps prevent interference with peripheral devices
Strong wrist for handling tooling and product with confidence
Rear or bottom cable exit to support cleaner, more protected routing
Typical M20iB/25 applications
Packaging
Reliable performance in environments where moisture, dust, or debris are present.
Machine load / unload
Handles exposure to coolant mist, chips, and grime common in machining operations.
iRVision and other intelligent technologies can be integrated into M20iB/25 systems to support
inspection, guidance, and decision-making at the robot.
