Mitsubishi MR-J3BUS40M-B SSCNET III Optical Cable 40m for MELSERVO MR-J3 & MR-J4

The Mitsubishi MR-J3BUS40M-B (MR-J3BUS40M-B) is a high-flexibility, long-distance optical fiber communication cable engineered for SSCNET III and SSCNET III/H motion network architectures. Measuring 40 meters in length, this optical bus cable provides high-speed data transmission between servo system controllers and compatible servo amplifiers. It features dedicated servo controller and servo amplifier connectors, establishing optical communication across industrial motion control installations. The cable is built with high bending life and enhanced flex resistance, making it suitable for demanding routing environments and extended conduit runs. The MR-J3BUS40M-B connects host controllers to drive units across multiple Mitsubishi Electric automation series, including MR-J3-B, MR-J3W-B, MR-J4-B, MR-J4-B-RJ, MR-J4-DUB, and MR-JE-B servo drives. By utilizing optical fiber media, the cable delivers reliable long-distance connectivity while eliminating electromagnetic noise interference. Typical applications include automated assembly systems, packaging machinery, robotics, and material handling equipment requiring synchronized multi-axis motion networking.
