Belden 9451 004U, Multi Conductor Cable 2C 22 AWG PP PVC FR

Belden 9451 004U is a 1 pair audio cable with 22 AWG stranded (7x30) TC - Tinned Copper conductors, PP - Polypropylene insulation, and a PVC - Polyvinyl Chloride jacket. It features a tape shield made from Bi-Laminate (Alum+Poly) with 100% coverage, plus a 22 AWG (7x30) TC drain wire inside the foil shield to help reduce noise in signal and control wiring. The jacket and shield are bonded for removal on automatic stripping equipment to support faster terminations. Designed for indoor - riser, indoor use, it is rated 300 V (CMR) and meets UL 1666 Riser, IEEE 1202 FT4, and IEC 60332-1-2.
