1888020-4

TE Connectivity AMP Connectors's 1888020-4 redefines reliability in Pluggable Connectors for marine electronics. Specifically engineered to withstand saltwater corrosion, this connector system exceeds ISO 8099 standards while providing secure power and data connections in demanding maritime applications.The Receptacle design incorporates robust sealing features. Triple O-ring arrangements prevent water ingress at depths up to 10 meters, making it ideal for sonar equipment and underwater ROV connections.As a SAS, Mini specialist, this component supports hybrid power/data transmission. 8-pin circular versions deliver 30A power alongside 10Gbps Ethernet, simplifying wiring in modern navigation system installations.With 36 contacts, the connector optimizes vessel systems. 12-pin versions support NMEA 2000 networks with dedicated power, signal and grounding contacts for clean power distribution.Engineered for Surface Mount requirements on vessels, the connector features stainless steel mounting hardware. Bulkhead versions withstand 500-hour salt spray testing without corrosion, exceeding marine grade requirements.The Solder system ensures reliable connections in wet environments. Crimp-and-seal contacts prevent capillary action water migration, maintaining <5m resistance after 1000 thermal shock cycles.Board Guide address unique marine challenges. Polarized keying prevents mis-mating in low-light conditions, while UV-stabilized housings retain flexibility after 5 years of sun exposure on deck.Gold selection combats saltwater corrosion. Gold-nickel with palladium barrier layers demonstrates 10x better performance than silver in marine atmosphere tests.Precision 30.0µin (0.76µm) ensures long-term conductivity. The 2.5 m gold plating maintains <10m contact resistance after 5000 mating cycles - critical for reliable operation in harsh marine environments.
