2.5 ATA interface connector
The drive connector is a 44-conductor connector with 2 rows of 22 male
pins on 0.079-inch (2-mm) centers (see Figures 4 and 5). The mating
cable connector is a 44-conductor, nonshielded connector with 2 rows
of 22 female contacts on 0.079-inch (2-mm) centers. The connectors
should provide strain relief and should be keyed with a plug in place of
pin 20.
These drives are designed to support the industry-standard MCC direct-
mounting specifications. When installing these drives in fixed mounting
applications, use only MCC-compatible connectors such as Molex part
number 87368-442
x
. For applications involving flexible cables or printed
circuit cables (PCCs), use Molex part number 87259-4413 or equivalent
to connect the drive to the system. Select a connector that provides
adequate clearance for the master/slave configuration jumpers if the
application requires the use of such jumpers. The ATA interface cable
should be no more than 18 inches long.
Note. The I/O connector pins may extend up to 0.010 inches beyond
the edge of the head/disc assembly.
