When John Atanasoff constructed the first semi-electronic digital computing device in 1939 he never could have imagined that over sixty years later, Belkin Components would carry every SCSI cable imaginable. The External SCSI III Ultra Fast and Wide Cable is used to interface any two SCSI devices such as storage devices, wherein one has an Ultra Micro Centronics 68 female port and the other has a Micro DB68 Female port. PRODUCT FEATURES: Rated for SCSI III applications; Double shielded (braid and foil) to meet SCSI specifications and ensure compliance with FCC requirements reducing EMI/RFI interference; Low-capacitance impedance matched 28 AWG stranded tinned copper are individually insulated in polypropylene; Thumbscrews enable easy installation; 34 tightly woven conductor pairs ensure that each data line is paired with a ground line to minimize interference ensuring error-free data transmissions; State-of-the-art wiring design ensures 100% compatibility; Gold plated copper contacts for a clean, clear transmission; PVC premold encapsulates individual conductors to eliminate stress; Flextec PVC rubberized cable jacket is extremely flexible for use in tight areas; Aluminum undermold shield helps meet FCC requirements; Ground indents provide excellent conductivity and retention with mating connector.
