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 female con-
tacts with adjacent contacts .100 inch 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 male pins
with adjacent pins .100 inch apart. The connector is keyed (see Figure 11a).
Mating panel mount connector: 3M-CHE-2050-J01A10-KLE.
9.6.4.2
Mating connectors for “W” and “WD” models
The nonshielded cable connector shall be a 68 conductor connector consisting of two rows of 34 male contacts
with adjacent contacts .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 .050 inch apart. The connector is keyed by means of its shape (see Figure 11b).
9.6.4.3
Mating connectors for “WC” and “DC” models
The nonshielded connector shall be an 80 conductor connector consisting of two rows of 40 contacts with adja-
cent contacts .050 inch (1.27 mm) apart. See Figure 11c. 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 sup-
port a series of drives.
To insure that both drive connector and host equipment mating connector mate properly, both drive connector
and host equipment mating connector must meet the provisions of “SFF-8046 Specification for 80-pin connec-
tor for SCSI Disk Drives.”
