CANFORD KSM-LFH - OVERALL FOIL SCREENED SOLID CONDUCTOR MULTIPAIR CABLE (BBC PSN types) Low Fire Hazard

CANFORD KSM-LFH CABLE 5 pair (BBC PSN10/3 LFH version)

These cables, to a BBC specification but updated to low fire hazard (LSOH) standards, have single solid conductors, twisted in pairs and overall foil screens with drain wire. They are suitable for permanent installations where screens are terminated on a bus arrangement, such as jackfields and IDC type blocks. They have a relatively low impedance (they were designed before digital audio was invented) and are not suitable for digital audio circuits.
