SCSI 34 pair, 30 AWG (7/38) TC Unshielded Twisted Pair Cables
|
Basic construction of the SCSI Ultra 640 electronic cable uses 30 Gauge (AWG) stranded with FRFPO insulation. Conductors are then twisted into pairs with varying left-hand lays to reduce crosstalk. The required number of pairs are cabled with a left-hand lay, wrapped with a foam polypro tape. The non-shielded SCSI Ultra 640 cable is jacketed with Hi-Flex PVC.†
† Black (000) is standard for this product but other colors are available upon request.
