Typically the narrow scan cable has 50 pins.
SCSI, Fast SCSI, Ultra SCSI, Ultra2 SCSI: 8 devices Wide SCSI, Fast Wide SCSI, Ultra Wide SCSI, Wide Ultra2 SCSI, Ultra3 SCSI, Ultra160 and 160+ and Ultra320 : 16 devices Of course, the number of devices supported depends not only on protocol limitations, but cable length, number of cables used, etc.
50pin
The Small Computer Systems Interface device; which is usually a SCSI cable. :P
it appears that an SCSI cable can be installed in either direction. If not, then it will 1. not be able to be installed the wrong way 2. not work. you will simply have to switch it; no damage should be done
SAS is SCSI, it connects via a serial cable/connector instead of parallel (long and skinny) connector.
Ultra wide SCSI. wide SCSI buses support 16 devices, rather than the eight devices specified in regular SCSI.
Its a SCSI cable with a 50pin HD SCSI 2 connector on one side and a 68pin SCSI 3 connector on the other.
SCSI
The maximum length of cable that can be used for SCSI-3 is 12 meters. This is applicable to Ultra2 Wide, Ultra 160, and Ultra 320.
