Overview
Technical Details
Sales & Support
Spectrum Cable-Tech manufactures automotive wires across the three international standards that vehicle manufacturers specify: DIN 72551 and ISO 6722 for European platforms, SAE J1128 for American platforms, and JASO D 611 for Japanese platforms. Every grade is drawn from 99.9% pure electrolytic copper and insulated with flame-retardant compounds selected for the thermal, chemical and mechanical stresses of the environment it will sit in.
Range: FLRY-A, FLRY-B, FLR2X, FLY (DIN) · TXL, GXL, SXL, GPT (SAE) · AVSS, CIVS, AESSX (JASO)
DIN Standard Automotive Wires – German / European
Manufactured in compliance with DIN 72551 and ISO 6722, offering high temperature tolerance and lightweight performance. Thin-wall PVC grades reduce harness weight and bulk; the cross-linked polyethylene grade extends the working range to +150°C for engine-bay and powertrain routing.
European Range Overview (DIN 72551 / ISO 6722)
| Type | Standard | Insulation | Temp Range | Primary Applications |
| FLRY-A | DIN 72551 / ISO 6722 | Thin Wall PVC (Asymmetric) | -40°C to +105°C | Lightweight wiring harnesses, signal lines, dashboards |
| FLRY-B | DIN 72551 / ISO 6722 | Thin Wall PVC (Symmetric) | -40°C to +105°C | Main body wiring, door connections, vehicle harnesses |
| FLR2X | ISO 6722 | Cross-linked PE (XLPE) | -40°C to +150°C | Engine compartment, high-heat powertrain systems |

SAE Standard Automotive Wires – American
Engineered to meet SAE J1128 benchmarks, principally with cross-linked polyethylene (XLPE) insulation. Wall thickness rises from TXL through GXL to SXL, trading harness bulk against mechanical and abrasion protection; GPT covers general-purpose PVC circuits in the cabin.
American Range Overview (SAE J1128)

| SXL | SAE J1128 | Standard Heavy Wall XLPE | -40°C to +125°C | Off-road machinery, industrial engines |
| GPT | SAE J1128 | General Purpose PVC | -40°C to +85°C | Cabin interior wiring, lighting circuits |
JASO Standard Automotive Wires – Japanese
Engineered for Japanese OEM platform compliance to JASO D 611 and ISO 6722. AVSS provides compact, high-density PVC wire for signal circuits and lightweight harnesses; CIVS offers a flexible conductor arrangement for complex interior routing; AESSX uses heat-resistant cross-linked polyolefin for high-temperature engine bays.
Japanese Range Overview (JASO D 611 / ISO 6722)
| Type | Standard | Insulation | Temp Range | Primary Applications |
| AVSS | JASO D 611 | Thin Wall PVC, small size | -40°C to +90°C | Signal circuits, compact high-density harnesses |
| CIVS | JASO D 611 | Flexible Thin Wall PVC | -40°C to +90°C | Complex interior routing, flexible connections |
| AESSX | JASO D 611 | Heat-Resistant XLPE | -40°C to +120°C | High-temperature engine bay wiring |
