L77TWA11W1SMCSV4RRM6 is a Hybrid D'Sub connector conforming to MIL C24308, NFC93425, and HE507 standards. The connector features steel shells with tin plating, high-temperature black thermoplastic insulators, and machined bronze (female) or brass (male) signal contacts with gold plating (15 µm Au over 79 µm Ni minimum or 30 µm Au over 79 µm Ni minimum). Signal contacts are rated for 7.5 A with 10 A peak, while power contacts and various termination types (PCB, solder cup, crimp) support 10 to 40 A, and shielded contacts handle 0.5 A. The connector is available in multiple shell sizes with front or rear mounting configurations, offering dimensional flexibility for diverse industrial and aerospace applications requiring reliable hybrid signal and power transmission.
