TE Connectivity TRSA Heatshrink Cable Marker White, Pre-printed "7", Polyolefin, 3 mm to 1 mm, Flame TRSA-1019/C/1/7

TE Connectivity TRSA-1019/C/1/7 Heatshrink Cable Marker is engineered for professional cable identification applications, primarily within electrical and automation setups. This cable marker features a pre-printed legend "7" on a white polyolefin sleeve, providing high visibility and clear marking even in poor lighting conditions. The marker accommodates cable diameters ranging from 1 mm to 3 mm, making it versatile for various wire and cable sizes.

The construction is based on irradiated polyolefin, a material known for its robust heat-shrink capability. When exposed to temperatures above 120°C, the marker shrinks to 33% of its original diameter, ensuring a tight, secure fit and resistance against environmental factors. Flame retardancy is a key property, with compliance to ASTM D876 standards (burn time more than 5 seconds) and additional ISO and IEC certifications that confirm safety and durability in demanding industrial installations.

The cable marker achieves a 3:1 shrink ratio, making it easily and rapidly installed onto cables. It is suitable for environments where quick and reliable wire management is required. Designed for continuous temperature ranges from -55°C to +135°C (with short-term tolerance up to +300°C), the marker performs reliably across storage, operation, and maintenance functions.

TE Connectivity's TRSA cable marker assists engineers and installers in organizing and coding wires, facilitating efficient maintenance and troubleshooting in panel builds, wiring harnesses, and system upgrades. The legible black-on-white legend simplifies identification and speeds up project workflows. Tensile strength of 5 MPa ensures durability and resistance to mechanical stress.

This product complies with ISO 1817, ASTM D876, ISO 188, ISO 37, and IEC 243, supporting stringent operational requirements. The polyolefin material also demonstrates good resistance to common fluids, enhancing chemical compatibility and longevity in industrial conditions.

Engineered for rapid installation in electrical setups and cable management tasks. Pre-printed with legend "7" for precise marking and coding. Accommodates cable diameters from 1 mm to 3 mm; packs typically contain 100 markers.
