What this line is on the bench
The R88A-CA1C030SF-E: As a power cable rather than a signal or feedback lead, its job is to carry phase power and brake conductors between drive and motor — no encoder or resolver cores run inside this jacket, so any resolver feedback has to come in on a separate R88A cable.
Sourcing reality for the BOM line
For a procurement line that is waiting on this exact 30 m cable, the practical move is to quote it to order against an RFQ so the distributor pulls from the current Omron channel rather than guessing on the after-market reel. Compliance paperwork (RoHS, REACH, UL, IEC) travels with the part on the Omron documentation pack shipped against that RFQ; no separate certificate is encoded on the order code itself.
