FAQ
What does the -A suffix mean? It denotes a cable variant (often the amplifier-to-controller or specific length variant); confirm the exact MR-J3BUS03M-A orientation against your servo manual.
How long is the 40M? The 40M suffix indicates about 40 meters, for long machine-cell spans; exact tolerance per Mitsubishi drawing.
Is the jacket 6.0 mm? Supplier docx lists PE 6.0 mm for this round cord variant.
