66555-3

TE Connectivity Aerospace, Defense and Marine's 66555-3 represents a significant advancement in Rectangular Connectors - Contacts technology, developed specifically for harsh environment applications. Its ruggedized design ensures reliable operation in extreme conditions while maintaining electrical performance.The Pin configuration incorporates environmental sealing features that meet IP67 standards when mated. This design is particularly effective in offshore energy applications where saltwater exposure is constant.Utilizing Crimp technology, the contacts maintain electrical continuity even under mechanical stress. This termination method has been proven effective in mining equipment subjected to constant vibration.Engineered for 24-28 AWG conductors, the contact system prevents moisture ingress while maintaining proper strain relief. The design has been validated through extensive salt fog testing.The Gold surface treatment provides exceptional resistance to chemical exposure, making it ideal for chemical processing plants. Accelerated aging tests show superior performance in acidic environments.With 50.0µin (1.27µm) coating, the contacts maintain reliable performance despite abrasive contamination. This specification is critical for construction equipment operating in dusty conditions.
