What it is and where it runs
The Mitsubishi MR-JCCBL20M-L is a 20-meter encoder feedback cable designed for MR-J4 servo drive systems, carrying position and velocity signals between the servo motor encoder and the drive for precision motion control.
Sourcing and lifecycle posture
No official successor part is identified in the record; for ongoing MR-J4 installations the MR-JCCBL20M-L remains the right-sized spec rather than a substitute hunt.
