Fanuc M-20iB/25 Robot

The fully enclosed powerlifter

The Fanuc M-20iB/25 robot is the first in a new generation of Fanuc M-20iB robots. Combining a lightweight hollow upper arm and wrist with advanced servo technology, the Fanuc M-20iB series has been designed to achieve faster cycles and increased throughput on a range of manufacturing applications. Models come fully encapsulated to IP67 standard, making them ideally suited to wet, dirty and harsh processes such as automatic deburring.

Enclosed construction

NO exposed cables and motors for minimal interference and maximum reliability. Connectors don’t protrude, and the cables are shielded along the arm.

Demanding environments

Options for demanding environments and processes such as clean room, food handling and parts washing are available.

Smart offline programming

This robot model is integrated into the Fanuc's own offline programming software ROBOGUIDE. ROBOGUIDE is a powerful tool that enables integrators, planners and users to design cells, systems and motions offline.
