057-3025-000 is a circular connector from the VEAM CIR Series featuring bayonet coupling mechanism for secure connections in demanding environments. The connector is manufactured with an aluminum alloy shell with multiple finish options including hard black anodize, electroless nickel, and cadmium-olive drab, while the insert is made from polychloroprene (Neoprene) with optional silicone or fluorocarbon materials. Contacts are constructed from copper alloy or thermocouple alloys with silver, gold, or rhodium plating options. Produced in accordance with NATO Standard VG95234 based on MIL-DTL-5015 for physical size, layout, and environmental requirements, these connectors offer dielectric strength test voltages ranging from 1,000V to 7,000V AC rms depending on service rating. The CIR Series connectors are commonly used in aerospace, transportation, and industrial applications where reliable interconnect solutions are required in harsh environments.
