9.6.4 Mating connectors
Part numbers for the different type connectors that mate with the various Hawk 2XL I/O connectors are given in
the sections following.
9.6.4.1 Mating connectors for “N” models
The nonshielded cable connector shall be a 50 conductor connector consisting of two rows of 25 male contacts
with adjacent contacts 100 mils apart.
Recommended mating flat cable connector part numbers are:
[1] See Figure 10
The drive device connector is a nonshielded 50 conductor connector consisting of two rows of 25 female pins
with adjacent pins 100 mils apart. The connector is keyed (see Figure 11a).
9.6.4.2 Mating connectors for W models
The nonshielded cable connector shall be a 68 conductor connector consisting of two rows of 34 male contacts
with adjacent contacts 0.050 inch (1.27 mm) apart.
Recommended mating flat cable connector part numbers are:
[1] See Figure 10.
The drive device connector is a nonshielded 68 conductor connector consisting of two rows of 34 female pins
with adjacent pins 50 mils apart. The connector is keyed by means of its shape (see Figure 11b).
9.6.4.3 Mating connectors for WC models
The nonshielded connector shall be an 80 conductor connector consisting of two rows of 40 contacts with adja-
cent contacts 50 (1.27 mm) mils apart. I/O connection using a cable is not recommended. The length and size
of the host equipment DC power carrying conductors from the DC power source to the host equipment 80 pin
disk drive interface connector(s) should be strictly designed according to proper power transmission design
concepts. No possibility for the equipment user to attach an 80 pin cable/connector should be allowed, since
the length of the DC power carrying conductors could not be controlled and therefore could become too long
for safe power transmission to the drive. Daisy-chain 80 conductor cables should especially not be allowed,
since the power-carrying conductors on the 80 conductor interface were not intended to support a series of
drives.
Recommended PCB or bulkhead mounted connectors are:
