Completely Enclosed M20iB
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.”
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.
Where the M-20iB really earns its keep
Keeps pace near sanitation zones without constant attention.
Reduces buildup that causes early wear and downtime.
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.
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
iRVision and other intelligent technologies can be integrated into M20iB/25 systems to support inspection, guidance, and decision-making at the robot.
