Are these genuine FANUC parts?
No. These are OEM-compatible replacement parts manufactured to FANUC specifications for maintenance and repair; we primarily supply domestic (non-original) replacements. Please confirm condition and availability with us before ordering.
How do I confirm the correct cable for my system?
Before ordering, verify the FANUC part number on your cable label, your controller / CNC model (e.g. FANUC Series 0i, 0i-Mate, 30i/31i/32i, or robot controller R-30iA / R-30iB), and the connector marking (JD1A / JD1B / JD51A). If you are unsure, send us a photo of the part label and connectors and we will confirm the correct replacement.
What is the lead time and warranty?
