TE Connectivity TRSA Cable Marker, Pre-printed Legend "4", Heat Shrink Polyolefin, White, 4 - 12 mm, Flame TRSA-1019/G/1/4

TE Connectivity TRSA-1019/G/1/4 Cable Marker is a high-performance heat shrinkable cable marking solution designed for use in electrical, automation, and cable management applications. This marker is pre-printed with the legend "4" in black on a white polyolefin sleeve, ensuring easy and clear cable identification even in low-light conditions. With a nominal internal diameter range of 4 mm to 12 mm, it is ideal for marking cables of varying sizes in industrial, commercial, and laboratory environments.

Constructed from irradiated polyolefin, the marker exhibits excellent flame retardancy as per ASTM D876 standards, with a burning duration of less than 30 seconds for enhanced fire safety. The heat-shrink capability allows the marker to shrink to just one-third of its supplied diameter when heated above 120°C, firmly securing it to cables and providing robust labeling. The material delivers good chemical resistance, withstanding exposure to common fluids typically encountered in maintenance and manufacturing settings.

The marker maintains integrity across wide operating temperatures, from -55°C to +135°C and up to +300°C for short-term exposures, ensuring reliability in both indoor and outdoor installations. Compliance with rigorous international standards such as ISO 1817, ISO 188, IEC 243, ISO 37, and ASTM D876 assures compatibility and durability in demanding environments.

Its 3:1 shrink ratio simplifies installation, making it suitable for rapid deployment in industrial control panels, plant wiring, HVAC systems, and lab setups. The pre-printed legend enables standardized cable identification, improving maintenance efficiency and reducing errors during connection and troubleshooting. The marker’s tensile strength of 5 MPa provides mechanical robustness for secure cable management.

TE Connectivity cable markers are widely used in applications including industrial automation, manufacturing lines, commercial wiring, laboratory setups, and electrical panel installations. The combination of reliable material, high flame retardancy, clear pre-printed legend, and international standard compliance makes it suitable for professional cable management needs.
