FLRY-B Automotive Cable Series

Low-voltage PVC-insulated wire with Class B copper conductors, engineered for space-saving performance and certified to ISO 6722, RoHS, and REACH standards.

Overview

FLRY-B (Flexible Low-voltage Reduced-insulation Thickness, Type B) is a standardized automotive cable type used throughout the industry for low-voltage vehicle wiring systems. The abbreviation reflects its key characteristics: flexible copper conductor, PVC insulation with reduced wall thickness, and Class B conductor stranding.

The FLRY-B automotive cable series from Celestix is a family of lightweight harness solutions, featuring flexible construction and thin-wall insulation for optimal use in compact vehicle platforms. Engineered with copper conductor options and PVC insulation, each wire is built for high performance in interior and body electronics, especially where space, weight, and durability matter.

This single-core cable family spans cross-sections from 0.35 mm² to 25 mm², and supports low to moderate current loads in automotive circuits. Manufactured in-house at our ISO-certified facilities, every cable aligns with international cable standards including ISO 6722, DIN 72551-6, and RoHS/REACH.
