Belden 9451 010, Audio Cable 2C 22 AWG Beldfoil Shielded CMR

Belden 9451 010 is a 1 pair audio cable built with 22 AWG stranded (7x30) TC - Tinned Copper conductors and PP - Polypropylene insulation. It uses a tape shield made from Bi-Laminate (Alum+Poly) with 100% coverage plus a 22 AWG (7x30) TC drainwire to help reduce noise in line level audio, control, and communication circuits. The PVC - Polyvinyl Chloride jacket features a bonded jacket/shield design for compatibility with automatic stripping equipment. It is rated CMR with a UL voltage rating of 300 V (CMR).

Belden 9451 010 Key Features

• 1 pair construction with 22 AWG stranded (7x30) TC - Tinned Copper conductors.
