What is SCSI, pronounced Skuzzy? No, it's not some sort of inappropriate language used to belittle a person. SCSI stands for Small Computer System Interface; it's a cable that attaches peripheral devices, such as a CD-ROM, to your computer. The Micro DB50 Male to Centronics 50 Male Pro Series SCSI II (fast SCSI) Cable is used to interface two SCSI II devices, like a scanner and a CD-ROM, wherein one has a Micro DB50 female port and the other has a Centronics 50 female port. PRODUCT FEATURES: Rated for SCSI II applications; Double shielded (foil and braid) 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; 25 tightly woven conductor pairs ensure that each data line is paired with a ground line to minimize interference ensuring error-free data transmissions; 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.
