How to Choose the Right Automotive Cable

Operating voltageStandard 12V/24V systems use 60V-rated FLRY/FLY cable. EV/PHEV high-voltage systems require 600V-rated HV cable per ISO 6469.
Thermal installation zoneConfirm location (passenger area, engine bay, exhaust-adjacent) and select the corresponding temperature class.
Color codingSpecify EU standard color codes or a custom color-stripe scheme. Include color chart in RFQ.
EMC and shieldingCAN bus, LIN bus, and camera cables require shielding. Specify data rate and bus protocol in RFQ.
