Features

• 2:1 Contraction Ratio: Heat activation allows the flat polyolefin tube housing to shrink down cleanly for a snug, secure fit over specialized wires.
• Flame-Retardant Integrity: Fully compliant with industrial safety standards, offering secure electrical insulation and thermal resistance in active panel setups.
• High-Contrast Alphanumerics: Sharp black print layout over a clean white surface backing maximizes structural readability for complex wiring configurations.
• Durable Polyolefin Construction: Robust non-adhesive material formula resists long-term solar UV fading, moisture entry, and chemical smearing.
• Seamless Fit Guide: Optimally sized to pass easily over small terminals and shrink onto cords measuring between 2.6mm to 5.1mm in diameter.

Applications

• Industrial Switchgear Wiring: Permanent numbering and marking of primary power conductors inside main electrical panels.
• Telecom Network Maintenance: Color-safe tracking markers for high-density fiber strands, server lines, and patch bay interfaces.
• Automation PLC Calibration: Indexing multi-tier programmatic terminal boards and sensor cables in manufacturing environments.
• Harsh Environment Tagging: Heavy-duty cable marking for aerospace, marine electronics, and outdoor weather-exposed gear setups.

Usage

• Power off your industrial Brother P-Touch label marker system and pop open the primary rear layout compartment cover panel door.
• Check the flat guide window of the new 8.8mm polyolefin cassette to confirm the continuous material is feeding straight.
• Align the distinct plastic alignment notches on the cartridge frame with the internal printer engine spindle pins.
• Press down firmly until the heat shrink cartridge clicks level into the print engine bay.
• Close the console panel door, enter your wire markers array using the alphanumeric keyboard panel, and execute a print command.
• Slide the flat printed tube over the exposed end of a disconnected wire (diameter 2.6–5.1mm), then activate a thermal heat gun to shrink it securely into place.
