Products that shrink wiring footprints
SEPM’s public catalogue historically splits into Flat Component and Electronic Wires — covering board-to-board FFC through irradiated and high-voltage constructions.
SUMI-CARD™ Flexible Flat Cable
Sumitomo’s FFC brand — flat rectangular conductors between insulation films for compact, dynamic routing down to 0.5 mm pitch.
- 0.5 mm pitch
- High frequency
- High temp / humidity
- Halogen-free options
Electronic Wires Division
UL- and CSA-recognized insulated electronic wires designed for dense wiring in smaller, higher-performance devices.
- Heat-resistant PVC
- SUMIFLEX™
- Piercing connector wire
- Spiral shielded
IRRAX™ Irradiated Wires
Cross-linked wire families for heat, voltage, and flexibility demands — including V2, HF, B, and high-voltage constructions.
- IRRAX V2
- IRRAX HF
- IRRAX B
- High-voltage wire

Built for volume interconnect
Archive materials describe a 59,003 m² footprint with 31,277 m² of built-up space across six plants (M1–M6). Production shifted to Tebrau Industrial Area 2 in 1993 with FFC in M1, then expanded through device wire, IRRAX™, automotive, and high-voltage lines.
