Low-noise, single-core screened cables for use in low-level signal circuits. The plain copper stranded conductors are insulated with polythene with PE over which is a layer of semiconducting polythene with PE. This is plain copper braided and Black PVC sheathed overall. Nominal impedance is 50 Ω.
Caution
When connecting a plug, ensure that black semiconductor layer is stripped back to braiding. Not suitable for r.f. use.
