ITT CANNON MDM21PH003L Micro-D Metal Shell Connector

The ITT CANNON MDM-21PH003L Micro-D Metal Shell Connector is a robust solution for applications demanding compact size, high reliability, and electromagnetic shielding. Constructed with an aluminum shell, it provides enhanced strength and prevents chipping or cracking, while also offering EMI and RFI shielding. The silicone elastomer interfacial seal ensures a moisture and humidity barrier between contacts and the shell. Ideal for use in aerospace, military, and industrial environments, the MDM series accommodates from 9 to 100 contacts, including power and coaxial configurations. Its .050" contact spacing and various termination options make it versatile for a wide range of applications.
