2 A high density, harsh environment connector designed to meet the most demanding environmental conditions and RFI/EMI shielding requirements. Delphi Connection Systems delivers high quality, high reliability and high density connectors that you have come to rely on. 2. Delphi Connection Systems

3 MIL-C Shock Resisting Circular Connectors Military, commercial, and industrial electronics systems benefit from Delphi Connection Systems harsh environment circular connector. The connector provides: High contact density (without a decrease in contact spacing) Scoop-proof aluminum shells designed for maximum protection Threaded couplings Five-key polarization options Fluorosilicone rubber sealing provides fluid immersion protection Cadmium over nickel shell finishes for maximum corrosion resistance Resistance to MIL-S-901 shock testing Contents Characteristics, Benefits, Features and Applications The MIL-C miniature circular connector offers a variety of features and benefits including a unique retention system. This system provides a retention clip on the contact to offer maximum economy and improved field serviceability. Delphi's M28840 connectors are available in a wide range of backshells and strain reliefs for increased versatility with each application.
