Belden 9451 002U is a 1 pair 22 AWG audio and control cable with stranded (7x30) TC - Tinned Copper conductors, PP - Polypropylene insulation, and a PVC - Polyvinyl Chloride jacket. It uses a Beldfoil® tape shield with 100% coverage plus a 22 AWG (7x30) TC drain wire to help reduce noise in line level audio, computer communication, and low voltage analog or digital control circuits. The jacket and shield are bonded to support automatic stripping equipment. It is rated for indoor riser applications and is UL listed for Article 800, CMR with a 300 V (CMR) voltage rating.
