FAQ
What does 03M mean? It is the Mitsubishi order-code length suffix – 03M = about 3 meters. Other suffixes (015M, 1M, 2M, 5M etc.) give other lengths.
Which amplifiers does it fit? Supplier listings state MR-J3-B and MR-J4-B series, including MR-J4W2-B / MR-J4W3-B multi-axis amplifiers; confirm your exact servo model.
Is the jacket 6.0 mm? Yes – the supplier docx calls this out F07-OD 6.0MM-G gray round cord, as photographed.
Why Choose Us
TOCP Fibercable supplies H-PCF and PMMA POF industrial fiber jumpers with supplier parameters checked before quoting, and flags designations that need confirmation rather than overstating compatibility. Read our FAQ for H-PCF and POF fiber assemblies, or return to the home page.
