50 Pin IDC 50 pin insulation displacement connector (IDC) used on ribbon cables for internal SCSI cabling. Female type used on cables, male on device or host adapter. |
 |
| Internal 68 Pin Micro-D Used on the P-cable for 16-bit WIDE SCSI. 68-pin version of the 50-pin micro-D high-density connector. Although the thumbscrew fastener is specified in SCSI-3, some manufacturers have used the spring-latch fastener. Male connector used for external cables, female for external devices. |
 |
| 80 Pin SCA The extra Pins in this Connector are used to provide power to SCA (Hot Swap) Drives. Found mostly on high end servers. |

50 Pin Centronics At one time the most common type of SCSI Connector, The 50 Pin Centronics Connector is starting to become less and less common. Used mostly with older 5 MB SCSI-1 Systems. |
 |
| 25 Pin D Sub Commonly used in the Apple/Mac world. This Connector is seen increased use on Scanners and Iomega Zip Drives. |
 |
| 50 Pin MicroD (High Density) Most 8-bit SCSI FAST (up to 10 Mbytes/sec) computers and host adapters use this 50-pin High-Density connector. |
 |
| 68 Pin MicroD The most common SCSI Connector used today. Used on all SCSI Wide applications this connector provides a highly secure connection. |
 |
| .8mm Very Ultra High Density Also called a Very High-Density Connector Interface (VHDC1) or 0.8-mm connector. It's similar to the SCSI-3 MD68 connector in that it has 68 pins but a much smaller footprint. |
