638187-4

TE Connectivity AMP Connectors's 638187-4 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 Socket 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 22 AWG conductors, the contact system prevents moisture ingress while maintaining proper strain relief. The design has been validated through extensive salt fog testing.The Tin 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 80.0µin (2.03µm) coating, the contacts maintain reliable performance despite abrasive contamination. This specification is critical for construction equipment operating in dusty conditions.
