Brother HS2-621 9mm Black on Yellow Heat Shrink Tube Label Tape

The Brother HS2-621 is a heat-shrink tube label tape designed for cable and wire identification with compatible Brother P-touch label printers. The HS2-621 format is approximately 9mm wide and 1.5m long, with a heat-shrink tube designed to fit around compatible cables after heating. The corresponding Brother HSe-621E genuine heat-shrink tube is specified at 9.0mm wide, 1.5m long, with a 3:1 shrink ratio and recommended cable diameters of 1.6mm to 5.4mm.

Product Features

Heat Shrink Tube Format

The HS2-621 uses a heat-shrink tube format rather than conventional adhesive label tape. After printing, the tube is positioned over the cable and heated so that it contracts around the cable for identification.

Black on Yellow Printing

The heat-shrink tube uses a black-on-yellow format, providing high-contrast identification for cables and wires. The genuine Brother equivalent is officially specified as black on yellow.

Approximately 9mm Width

The HS2-621 format is associated with the 9mm heat-shrink tube size. Brother’s current HSe-621E specification lists the tube at 9.0mm wide.

1.5m Length

The corresponding Brother heat-shrink tube is supplied as a 1.5m roll, providing material for multiple cable identification labels depending on the required label length.

3:1 Shrink Ratio

The Brother HSe-621E equivalent uses a 3:1 shrink ratio, allowing the tube to contract around compatible cable sizes after heating.

Cable and Wire Identification

The heat-shrink format is designed for identifying cables and wires and can be used in electrical, telecommunications, networking, control-panel, and installation environments.

Non-Adhesive Tube Design

Heat-shrink tube does not rely on conventional adhesive to remain around the cable. Once heated, the tube contracts around the cable.
