Female connector from the CMM320 series designed for crimping AWG 24-28 Low Frequency (LF) contacts. It features an insulator made of special PPS (Polyphenylene Sulfide Fiberglass filled thermoplastic) with UL 94-V0 flammability rating, offering radiation resistance, no humidity absorption, and oxygen-free properties, recognized for space applications. The contacts are made of copper alloy and beryllium copper with nickel and gold plating. Jackscrews are stainless steel. This connector offers robust electrical performance with max currents of 3A (25°C) and 2.2A (85°C), working voltage of 800V DC, and minimum insulation resistance of 1000 MΩ. Mechanically, it withstands 500 mating cycles and operates in a wide temperature range of -60°C to +260°C, with high resistance to vibration, shock, solvents, salt spray, and humidity.
