Unshielded U320 30 AWG round SCSI NexZ0 consists of 34 twisted pairs with 30 AWG stranded primaries. Round construction allows easy routing within box and increases airflow over flat equivalents. Differential impedance is 120 ohms ±5 ohms, and meets SPI-3/-4 electrical requirements. Cable's 0.024 in. primary overall diameter permits easy lamination on 0.025 in. center for termination with IDC connectors. Cable is suited for internal point-to-point assemblies.
