## Long description

Brady M21-375-C-342 is a black polyolefin label cartridge designed for thermal transfer printing with compatible handheld printers such as the BMP21 PLUS. The cartridge supplies heat-shrink PermaSleeve® style sleeves and is intended for durable identification on wires, cables and small components where a flexible, heat-resistant label material is required. Labels are supplied on a roll with a 9.53 mm roll diameter, 1.64 cm label width and approximately 2.13 m total length for multiple marking applications.
Advantages
The black polyolefin construction provides a resilient, heat-shrink sleeve that conforms tightly to wire and cable surfaces after thermal application. Thermal transfer printing produces legible, fade-resistant and smudge-resistant markings suitable for long-term identification. The cartridge format combines label supply and ribbon in a single unit for straightforward replacement and continued operation with compatible printers. The material’s range of temperature tolerance supports use in demanding environments where cold resistance and elevated temperature performance are required.
Suitable for
 Marking and identifying wires and cables
 Labeling small electrical components and harnesses
 Applications requiring heat-shrink, permanent sleeve identification
 Field service and maintenance work with handheld thermal transfer printers

How to use
Install the Brady M21-375-C-342 cartridge into a compatible thermal transfer handheld printer following the printer manufacturer’s instructions. Print the required text or symbols using the printer’s settings for thermal transfer media, apply the printed sleeve over the target wire or component, and apply heat as recommended by the sleeve manufacturer so the sleeve shrinks and conforms to the substrate to form a permanent marking. Use appropriate heat source and technique to ensure even shrinkage without damaging surrounding components.
Usage recommendations
For best results, verify printer ribbon compatibility and select printer settings optimized for polyolefin heat-shrink sleeves. Allow printed characters to fully develop before shrinking, and apply heat evenly along the sleeve length. Use in environments within the material’s specified temperature tolerance and test adhesion and legibility on representative samples when using on unfamiliar substrates.
