TE Connectivity Heatshrink Polyolefin Cable Marker, Pre-printed "S", White, 6 mm Max Cable, 2 mm Min Cable TRSA-1019/E/1/S

TE Connectivity TRSA-1019/E/1/S is a high-quality heatshrink cable marker made from irradiated polyolefin material, engineered for industrial cable management and identification. This cable marker is pre-printed with the letter "S" in black on a white background, optimizing visibility and identification for electrical installations, control panels, and wiring systems.

Designed to fit cables ranging from 2 mm up to 6 mm in diameter, this marker offers versatile use in electrical, automation, manufacturing, and commercial environments. The polyolefin construction provides robust insulation and mechanical protection, and the 3:1 shrink ratio ensures a tight fit after application, shrinking to one-third of its supplied size when heated above 120°C.

Flame retardancy is a key feature, with compliance to ASTM D876 and other international standards, ensuring safety during prolonged operation. The product is resistant to common fluids and chemicals, suited for environments where maintenance and reliability are critical.

Operational from -55°C up to 135°C continuously (with short-term resistance to 300°C), the cable marker can be used in demanding industrial settings such as factories, control cabinets, machinery installations, and laboratory wiring. The legend remains clear under poor lighting conditions, supporting fast identification during maintenance or troubleshooting.

The TRSA series provides additional benefits such as easy and rapid installation, rugged construction, and compatibility with industry-standard cable sizes. Three size options are available within the range to suit further cable diameters. The marker’s compliance with ISO 37, ISO 1817, ISO 188, IEC 243, and ASTM standards reflects its suitability for international projects and regulated sectors.

Typical uses include industrial automation, HVAC, manufacturing lines, commercial buildings, laboratory setups, and any scenario requiring dependable cable identification and management. These markers are supplied in bags for convenient bulk installation, helping professionals comply with electrical safety and organization standards.

Highly visible pre-printed Cable Marker for clear cable identification. Made from flame-retardant, durable polyolefin material. Suitable for cable diameters from 2 mm to 6 mm. White marker with black legend ensures high contrast and readability.
