Mogami W2965 PURO II Dual Subminiature & Miniature Coaxial Cable (Black, 500' Roll)

Stock your workbench for custom audio cable builds with a full 500-foot spool of Mogami W2965 PUROFLEX II. This flexible, black zipper-style cable pairs two miniature 75-ohm coaxial paths in a compact design for custom audio wiring and impedance-matched video connections. Neglex oxygen-free copper conductors, spiral shielding, and a soft PVC jacket combine signal-focused construction with easy handling.

Full 500-foot spool: Each quantity ordered includes one continuous 500-foot length of bulk cable. Order a quantity of 1 for one 500-foot spool. This is unterminated cable, not a preassembled cable or a by-the-foot listing.

Flexible Cable for Custom Builds

When standard coaxial cable is too bulky or stiff for the job, W2965 offers a superflexible miniature alternative. The dual, single-conductor layout keeps two coaxial paths together, while the rubber-like PVC jacket and satin finish make the cable easy to handle during custom assembly and routing. A full spool lets you cut individual lengths as your projects require.

Built for Audio and 75-Ohm Video Applications

Each coaxial path uses a 24 AWG Neglex OFC conductor with a served spiral shield. The low-capacitance construction suits audio patch applications, and the 75-ohm characteristic impedance supports impedance-matched video transmission. Clear cross-linked cellular polyethylene insulation surrounds the conductors.
