Micro-D Metal Shell - .050” Contact Spacing
MDM
Cannon MDM Series Microminiature Connectors are used in applications requiring highly reliable,
extremely small and lightweight solutions with higher density contact configurations. They are available
in eight shell sizes that accommodate from 9 to 100 contacts, as well as special arrangements with
power and coaxial contacts. Cannon MDM Series Microminiature Connectors employ size 24 Micro-Pin
/ Micro-Socket Contacts on .050 (1.27) centers in a contact density identical to the standard Micro-D
connector series, but with Aluminum shells to increase strength, prevent chipping, cracking or breaking
and provide electromagnetic (EMI and RFI shielding. They also feature a silicone elastomer compression
interfacial seal to provide a moisture and humidity seal between each contact and between the contacts
and shell.
