Product Description

The 3M SDR-3 Cable Marker, model SDR 3-89203, is a pre-printed adhesive marking tape specifically designed for efficient wire and cable identification in electrical and instrumentation applications. Manufactured from robust polyethylene terephthalate, this marker offers excellent adhesion while maintaining flexibility to conform around cables of various sizes. The tape displays the number '3' in high-contrast print for clear visibility.

This cable marker features a self-adhesive backing, making it simple to apply to both small and large gauge wires or cables. Its compact dimensions of 2.43mm width and 5.46mm length ensure it fits in confined spaces while providing reliable identification. The non-printable design means the legend cannot be changed, maintaining consistency and preventing tampering.

3M SDR-3 markers are engineered for use in diverse environments - ranging from commercial wiring panels to industrial control cabinets and field installations. With an operating temperature range from -40°C up to 121°C, it withstands extreme conditions found in power distribution, telecommunications, manufacturing, and automation systems.

The easy-to-dispense roll format allows users to pull and cut each label to their required length, increasing efficiency in labeling large projects or rapid maintenance operations. The marker’s white background enhances the legibility of the pre-printed black legend, ensuring clear identification even in low-light or high-density cable trays.

Common use cases include marking wires in control panels, terminal blocks, junction boxes, and switchgear, as well as organizing cables for scheduled maintenance and safety compliance in electrical, industrial, and communication systems. This marker supports quick troubleshooting, reduces wiring errors, and enhances system documentation efforts.

Engineered to meet the needs of professionals in electrical installation, facilities management, panel building, and industrial maintenance sectors, the 3M SDR-3 Cable Marker delivers lasting performance and reliability for structured cable management.
