The TE Connectivity TRSA-1019/G/1/7 heatshrink cable marker is engineered for reliable cable identification in industrial and commercial applications. The marker features a white polyolefin sleeve, pre-printed with a black '7' legend, making it ideal for clear marking even in low-light installations. It is designed to fit cables with diameters from 4 mm up to 12 mm, offering versatility for a broad range of wiring and cable management projects.
Constructed from irradiated polyolefin, the marker ensures robust performance with flame-retardant characteristics, meeting ASTM D876 burn duration requirements. When heated above 120°C, the marker shrinks to one-third of its supplied diameter, achieving a tight and secure fit that resists slippage and protects cable integrity. The 3:1 shrink ratio accommodates varying cable sizes and simplifies installation procedures.
Operational reliability is ensured across extreme temperature ranges, withstanding continuous exposure from -55°C up to 135°C and short-term peaks to 300°C. This makes the marker suitable for environments requiring high thermal resilience, such as manufacturing lines, laboratories, and electrical maintenance settings.
The polyolefin material is resistant to common industrial fluids, supporting consistent marker legibility and endurance. The distinctive '7' legend printed in contrasting black on white enhances identification accuracy among bundled wiring and complex installation layouts. Printable fields are not present, ensuring tamper-proof marking.
Compliance with international standards including ISO 188, ISO 1817, IEC 243, ASTM D876, and ISO 37 further attests to its technical quality and suitability for regulated applications. Tensile strength is rated at 5 MPa, supporting firm mechanical stability and operational safety.
This cable marker is an optimal solution for industrial cable management, electrical panels, laboratory setups, and wherever standardized cable identification is required. Its heatshrinking design, robust material specification, and high visibility legend streamline workflow and enhance maintenance efficiency.
