M83513/04-A04N is a Micro-D metal shell connector designed for highly reliable, microminiature applications requiring compact form factors with high contact density. This connector employs size 24 MICROPINTM/MICROSOCKETTM contacts on .050" (1.27 mm) centers and features solid uninsulated type (L) #25 AWG gold-plated copper contacts with multiple termination length options ranging from .125" to 3.000". The aluminum shell provides enhanced structural strength, electromagnetic (EMI) and RFI shielding, while the silicone elastomer compression interfacial seal ensures moisture and humidity protection between contacts. The connector is available in multiple shell sizes (9 to 100 contacts) and is designed to meet MIL-DTL-83513 specifications. These connectors are ideal for aerospace, military, and high-reliability applications where environmental sealing, compact packaging, and rugged performance are essential requirements.
