TE Connectivity TRSA-1019/C/1/U is an industrial heatshrink cable marker made from irradiated polyolefin, designed to provide precise cable identification and protection in electrical installations. This cable marker is pre-printed with the legend "U", allowing quick and reliable wire marking for maintenance, troubleshooting, and organization. Its white colour creates strong contrast, ensuring readability in poor lighting conditions.
Engineered for professional applications, the marker shrinks to 33% of its supplied diameter when heated to above 120°C, firmly adapting to various cable sizes with a 3:1 shrink ratio. It fits cables with diameters between 1 mm and 3 mm, accommodating common wiring in control panels, wiring harnesses, and cable management systems. The polyolefin material is highly flame-retardant, meeting ASTM D876 requirements, and resists burning for up to 30 seconds to maximize safety.
Offering operational resilience, the marker operates reliably across temperatures ranging from -55°C to 135°C, withstanding higher temperatures for short periods. It is compliant with multiple international standards, including ASTM D876, ISO 37, IEC 243, ISO 188, and ISO 1817, demonstrating its suitability for demanding environments in manufacturing, automation, industrial, and electrical maintenance sectors.
The product features easy and rapid installation, enabling efficient marking without the need for specialized tools. Its tensile strength of 5 MPa ensures stable positioning and robust performance, even when cables are subjected to mechanical stress. Resistant to common fluids, it maintains its integrity and marking clarity in commercial, industrial, and laboratory settings.
Common applications include cable management in data centers, industrial equipment, plant automation, control cabinets, and laboratory installations. The high visibility and heat shrink properties make it a reliable choice for engineers, technicians, and installers seeking secure, compliant cable marking solutions.
