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 Figure 4 on page 21 and Figure
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 SFF-8200
mounting specifications. When installing these drives in fixed mounting
applications, use only SFF-compatible connectors such as Molex part
number 87368-442
x
. For applications that involve 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.
Per SFF 8004 specifications, the I/O connector pins may extend
up to 0.015 inches beyond the edge of the head/disc assembly.
