Micro DB50 Images. Micro Centronics 50 Info. The Micro Centronics 50 connector has 50 pins arranged in two rows one on top of the other. This connector is typically used in proprietary SCSI-2 interface applications. This connector is rare. DB50 Info. The DB50 connector has 50 pins arranged in three rows one on top of the other. The top row has 17 pins, the middle row has 16 pins and the lower row has 17 pins.
Micro Centronics Info. The Micro Centronics 60 connector has 60 pins arranged in two rows one on top of the other. Most typically, external drive enclosures will have female connectors, while cables will have two male connectors. As with everything SCSI, there are exceptions.
Early SCSI interfaces commonly used a pin micro ribbon connector. This connector is similar to the pin connector used by Centronics for the parallel interface on their printers, thus the connector became popularly known as "Centronics SCSI" or "CN". Apple used DB connectors, which, having only 25 pins rather than 50, were smaller and less expensive to make, but decreased signal integrity increasing crosstalk [ citation needed ] and cannot be used with differential signaling.
Furthermore, DBs were commonly used for RS serial cables and also to connect parallel printers, meaning that users might accidentally try to use completely inappropriate cables, since the printer and serial cables would fit the connector properly and be hard to visually distinguish. Sun also used DBs on a few products. Apple Macintosh laptops used a squarish external SCSI connector called an HDI High Density Interconnect on the laptop itself not on the peripheral end of the cable, unless two laptops were being connected.
IBM 's early RS workstations sometimes used a "High Density Centronics" connector, which was a Centronics-style connector with smaller pins and shell. For some reason [ citation needed ] it had 60 pins, and is thus known as the "HDCN60". Certain Japanese digital camera manufacturers wanted to put SCSI into their equipment, but conventional connectors would have been too large. Some manufacturers used a DC connector, often incorrectly referred to as a DB These will most commonly be seen on three-cable systems, which are typically bit or bit "Wide SCSI" systems.
Extra confusion is generated here since this connector was also frequently used with SMD disk drives, which are completely incompatible with SCSI drives. With the arrival of SCSI-2, the situation was a bit less chaotic. As time went on, some manufacturers desired connectors even smaller than the SCSI-2 connector. There are 68 pins on the connector in two rows; the pins are 0. This connector is reputed to suffer fewer bent pins than the pin SCSI-2 connector despite its minuscule pins. There are adapters between most types of parallel SCSI connector, and some companies will manufacture custom cables to guarantee having the correct connectors.
An adapter from narrow to wide must include termination to work properly. While interconnectivity of a number of devices may look straightforward, there are many pitfalls, and with older SE devices the cabling length becomes an issue as signal degrades.
Many manufacturers have devised systems in which a SCSI disk drive or other device was placed in a small "caddy" container also called a " drive sled " , which carried connections for both power and data. The caddy or canister would be placed in a larger enclosure. Some of these systems allowed for hot swap drives could be replaced with the system running , while others allowed " warm swap ", in which the SCSI bus was "quiesced" meaning all drive activity was stopped but remained powered on with devices ready.
Digital Equipment Corporation's StorageWorks products were one system of this type. DEC briefly allowed third parties to license this system, but reversed the decision after less than a year; as a result, third-party StorageWorks products are quite rare. Compaq also made a drive caddy system for the Proliant line of servers. Compaq purchased DEC, and Hewlett-Packard later purchased Compaq, and the Proliant and StorageWorks names were reused on other storage products, including later hot-swap systems.
Some of these caddy systems were OEM manufactured, which means that the same product could appear with numerous brand names and model identifications. Serial SCSI disk-drives use smaller connectors due to the reduced number of signals required. There are three types of physical layer transports specified:. The drives themselves would use one of the other three connector types.
The situation is fundamentally similar to that of Parallel SCSI drive caddies; there have been a range of manufacturers, and the caddies themselves contain a generic device with one of the standard internal connectors which can be removed and replaced.

SCSI is a bus technology, which means that all devices connect to a central bus and are "daisy-chained" together.
The SCSI bus is controlled by a host controller which will typically be built into the motherboard, or it can be from a separate expansion card. A SCSI connector is either external or internal. The most important things to remember when selecting your SCSI cable is the type of connector required by your devices, and the location of the cable, either internal or external.
The top row has 34 pins and the lower row has 34 pins. The pin arrangement closely resembles that of a Centronics type interface. We're here to help, just contact us! What are SCSI connectors?

National Instruments pin SCSI cables are primarily used on previous generations of NI DAQ hardware family models, USBxx (formerly M Series). *Most pin Wide SCSI cables can be made w/ a variety of pin (Narrow) SCSI ends for 'Wide-to-Narrow' hybrid cables. Components used on.8mm VHDCI cables. This connector block provides a simple method of connecting to Pin SCSI Style Micro-D connectors. The screw terminals use a rising cage clamp mechanism.
