CANFORD MST - MINIATURE HELICAL SCREENED STRANDED CONDUCTOR TWIN CABLE
An extremely small overall diameter, ultra-thin strand twisted twin conductor cable, with Kevlar reinforcement within each conductor for greatly increased resistance to breakage. It is intended specifically for applications such as lapel microphones, where cable size and flexibility is a primary consideration, and internal equipment wiring where space is at a premium.
Application note: Because the copper wires are interwoven with the Kevlar fibres to give the cable its strength, a higher soldering temperature is required than for plain copper. The bit temperature should be around 370°C. Care must be taken not to melt the insulation.
This cable is similar to that used by Sony on the ECM77 microphone
