"SCSI-3 cables from L-com are manufactured to meet or exceed SCSI standards. Connectors are half pitch 68 position male on both ends with die cast zinc alloy backshells. Features double shielded low smoke zero halogen cable (copper braid plus aluminum mylar foil) and 34 pair polypropylene insulated 28 AWG conductors for the highest quality. Low smoke zero halogen cable reduces the amount of toxic and corrosive gases emitted during combustion. Typically used in poorly ventilated areas, low smoke zero halogen is becoming very popular with military contractors and anywhere the protection of people and equipment from toxic and corrosive gases is critical. Thumbscrews are 2-56 threaded to fit most applications. Twisted pair cabling reduces cross talk. Will ship immediately if in stock."
