1771477

Phoenix Contact's 1771477 delivers military-grade reliability for Heavy Duty Connectors - Inserts, Modules applications in extreme environments. The corrosion-resistant design combines hermetic sealing with rad-hard materials for nuclear and offshore applications. Where standard connectors fail, this solution maintains uninterrupted performance through sandstorms, salt spray, and high radiation exposure.Configured as Insert without Contacts, the module features explosive atmosphere protection meeting ATEX Category 1G/1D requirements for hazardous locations.The Female interface incorporates redundant sealing systems that maintain IP69K protection even after repeated mating cycles in contaminated environments.With 16 configuration, the design allows for separate containment of intrinsically safe and non-intrinsically safe circuits.The B16 form factor achieves NEMA 4X compliance while providing sufficient conductor spacing for 2500V isolation in damp conditions.Crimp termination is enhanced with chemical-resistant potting compounds that prevent wicking of corrosive fluids into contact areas.The 600V rating is maintained through fluoropolymer insulators that resist degradation from UV exposure and chemical contact.Designed for 15A continuous operation, the contacts utilize cladded materials that prevent galvanic corrosion in saltwater immersion.CK 2.5-ED contacts feature welded secondary retention systems that prevent contact movement under explosive decompression conditions.The -40°C ~ 125°C range is achieved through metal-to-glass hermetic seals that prevent moisture ingress while allowing for thermal expansion.
