D Subminiature
Commercial Micro D — MDSM
MDSM is the commercial industry’s
smallest D-type connector for shielded
I/O wire-to-board applications.
Requiring less than 1/3 the area of a traditional
D Subminiature connector, MDSM is designed for
situations where space and EMI shielding are the
primary design drivers.
Unlike other micro connectors, MDSM’s rugged
construction and unique contact design combined
with a PdNi contact finish provide durability of
10,000 mating cycles. All of this comes in a sleek
package that includes a snap together shield can
and a slide over boot producing a cable assembly
with an overmolded look and a low assembled
cost. MDSM is an ideal solution for applications
where size, shielding, durability and aesthetics are
key design criteria.

MDSM SSA Compatible Cable Assemblies
ITT Cannon’s 9 position MDSM connectors have
been designed into the ANSI specification called
SSA, ‘‘Serial Storage Architecture,’’ as the external
I/O. SSA is a new serial interface for
interconnecting storage devices, storage
subsystems, servers and workstations. Storage
subsystems are increasing in function, availability,
density and performance. With this comes the
trend for them to become more complex and
ITT Cannon has the interconnect system which
meets SSA’s high performance requirements.
SSA is an architecture which allows these new
subsystems to be implemented more easily and at
lower costs than other new high speed parallel
interfaces. SSA permits the transfer of data at
progressively higher speeds - 20 MB/sec interface
currently available with 40 MB/sec becoming
available in 1997/98. ITT Cannon’s MDSM
connector not only functions at these high speeds,
but also brings to SSA smaller, less cumbersome
and higher reliability cables and connectors than
current options.
ITT Cannon is offering SSA compatable external
cable assemblies in six different lengths to meet
your needs. These assemblies consist of two
MDSM 9SC type cable connectors terminated to
SSA specified external cable.
