In an attempt to trim the size of the connector, a 25-pin SCSI connector was designed for narrow SCSI.

SAS is SCSI, it connects via a serial cable/connector instead of parallel (long and skinny) connector.
Its a SCSI cable with a 50pin HD SCSI 2 connector on one side and a 68pin SCSI 3 connector on the other.

SCSI Harddrive:80-pin Connector The SCA interface was designed to provide a standard connection for systems using hot swappable drives. SCA interface drives connect to a SCSI backplane that provides power, configuration settings such as SCSI ID, and termination of the SCSI bus.

A SCSI (Small Computer System Interface) connector is used to connect and communicate between computers and peripheral devices, such as hard drives, scanners, and printers. It facilitates data transfer using a parallel interface, allowing multiple devices to be connected on a single bus. SCSI connectors come in various types, like 25-pin and 68-pin, depending on the specific SCSI standard and device requirements. Overall, the SCSI connector plays a crucial role in enabling high-speed data exchange and device management in computer systems.

First of all, remember that SCSI II is obsolete and is not used today or rarely.SCSCI II stands for Small Computer System Interface (Revision 2)SCSI II operates with a 32-bit data bus with an A cable and a B cableThe A cable consisted of a 50 pin Centronics connector. Pin outs here: http://www.interfacebus.com/SCSI_Differential_A_Cable_Pinout.htmlThe optional B cable consisted of a 68 pin connector**Click on the related link below
The beauty of SCSI is that supports many physical interfaces. Fibre channel SCSI uses 4 "pins" which can be copper, or fibre optic cabling. Parallel scsi which you are probably asking about can use 25, 50 or 68 pins. So you should rephrase your question to specify the interface you are asking about ... but I guess that would liook kinda dumb, ... "How many pins does a 50-pin SCSI interface have" :)
