8451-BLK-500 is a shielded single-pair multi-conductor cable designed for audio and low-voltage signal transmission applications. It features 22 AWG stranded (7x30) tinned copper conductors with polypropylene insulation and an overall Beldfoil shield providing 100% coverage, along with a 22 AWG stranded TC drain wire and PVC jacket. The cable has a nominal characteristic impedance of 45 Ohms, operates within a temperature range of -20°C to +75°C, and is rated for 300 V RMS maximum operating voltage. With an overall nominal diameter of 0.138 inches and CMR/CMG ratings for riser applications, this cable is ideal for professional audio, intercom systems, and general signal wiring where reliable shielding and consistent electrical performance are required.
