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
