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.
Applications:
Electronic Notepads
VME Cards
Multiplexors
Serial Storage Devices
Computer Workstations
Hand Held Devices
Bar Code Scanners
