CANFORD FSMB-LFH - FOIL SCREENED STRANDED CONDUCTOR MULTIPAIR CABLE - Audio and RS422 data, low fire hazard

Particular applications of FSMB2 include microphone circuits with DC operating pairs, RS422 data and talkback send/return. Note that this cable has a common drain wire. Impedance 100 ohms, suitable for both analogue and digital audio.

Wire insulation is polypropylene, which shrinks back minimally during soldering (considerably less than PVC or polyethylene). Wiring specifications for many public buildings call for LFH cables to be used in certain areas, notably in corridors etc. Under combustion circumstances, LFH cables have a significantly reduced smoke emission, and the gaseous products contain no toxic halogens.
