Mitsubishi SC-J3BUS20M-C(B) SSCNET III High-Flex Optical Bus Cable 20 m for MELSERVO MR-J3

The Mitsubishi SC-J3BUS20M-C(B) (SC-J3BUS20M-C(B)) is a 20-meter SSCNET III optical bus cable manufactured by Mitsubishi Electric System & Service for long-distance servo communication. It supports SSCNET III and SSCNET III/H communication and is built with ultra-high flex life for applications where the cable must withstand repeated bending. The cable is supplied with connectors for the servo amplifier communication ports and is intended to link motion control equipment and servo amplifiers in a MELSERVO MR-J3 system. Its 20 m length is intended for installations that need more reach than standard cabinet or outside-cabinet cables. SSCNET III uses optical fiber rather than copper conductors, so the cable carries high-speed serial communication between the controller and drive units without electrical noise pickup. Typical applications include positioning and motion control systems and other equipment using Mitsubishi servo amplifiers. The product is a fixed 20 m assembly; the SC-J3BUS□M-C family is available in 1 m increments from 1 m to 100 m when other lengths are required. Install it according to Mitsubishi's routing and bend requirements, and do not look directly into the optical connector or cable end while the system is powered.
