What SEACON does

SEACON is a specialized underwater connector brand, founded in 1964 and headquartered in El Cajon, California, that designs and manufactures electrical and fiber optic connectors for harsh marine and subsea environments. The portfolio spans over 2,500 product types across dry-mate connectors (mated in air before submersion), wet-mate/wet-pluggable connectors (mated while submerged), hybrid electrical/optical configurations, downhole oil-well connectors, field-installable products, underwater switches, penetrators for bulkhead cable routing, Ethernet (Cat 5/5e) connectors, and specialty items such as lightweight, tow-array, downhole-tool-insert, and coaxial connectors. Engineering differentiation rests on pressure-rated sealing, material science for seawater corrosion resistance, and wet-mate capability that enables subsea installation and maintenance without dry-docking.

The business model is project-based custom hardware sales sold through quote-based pricing under multi-year contracts. Primary end markets are oil and gas (offshore platforms, subsea production, deepwater drilling), defense and military (naval vessels and submarines), oceanographic research institutions, and ROV/AUV operators. SEACON does not operate as an independent commercial entity; it is wholly owned by TE Connectivity (NYSE: TEL, incorporated in Switzerland) and distributed through TE's global infrastructure — direct field-sales representatives for enterprise projects, authorized distributors, and the TE Store e-commerce platform — supported by 24/7 certified-engineer technical support across South America, Asia, Europe, Africa, and North America. Complementary services include after-sales support, field installation, testing facilities, in-house manufacturing, custom molding, design and engineering, R&D, and project management.

Products and services

• Electrical Dry-Mate Connectors Electrical connectors rated for underwater use up to specified depths, providing reliable dry-mate connectivity for electrical cables in marine environments. Designed for offshore, defense, and research applications where connections are made in air prior to submersion.
• Optical Hybrid Dry-Mate Connectors Fiber optic communication products offering hybrid dry-mate connectivity that combines electrical and optical capabilities within a single underwater connector assembly. Targets applications needing both power and high-bandwidth data through one interface.
• Wet-Mateable Electrical Connectors Electrical connectors engineered for mate and demate operations in submerged conditions, enabling installation and maintenance of subsea systems without requiring dry-docking. Targeted at subsea oil and gas, ROV/AUV, and defense operators.
• Electrical Wet-Mate Connectors Connectors designed to protect electrical terminals from external environments while maintaining reliable underwater electrical connections during wet-mate engagement. Used in subsea systems requiring ruggedized power delivery.
• Wet-Mateable Fiber Optic Connectors Fiber optic connectors with enhanced wet-mate connectivity for reliable underwater optical communication. Designed for high-bandwidth data transmission in submerged marine environments.
• Downhole/Oil Well Connectors Connectors designed for high-pressure operation in oil well applications, suitable for harsh downhole environments during drilling and production. Customized for specific pressure ratings and downhole tooling.
• Field-Installable Connectors Products enabling on-site installation and field assembly of underwater connectors, providing high reliability for oilfield condition assessment and remote deployment scenarios.
• Underwater Switches Modular underwater switch components designed for easy installation and replacement in submerged applications. Used within subsea systems for routing and control.
• Penetrators Cable assembly and bulkhead harness fixation solutions without connectors, available for fiber optic and electrical cable penetrations through pressure vessels and subsea enclosures.
• Specialty Connectors Specialized underwater connectors including lightweight connectors, towing array connectors, downhole tool inserts and boots, and coaxial connectors for specialized marine and subsea applications.
• Ethernet Connectors (Cat 5/Cat 5e) Underwater Ethernet connectors supporting Cat 5 and Cat 5e standards for reliable network connectivity in submerged applications, including ROV/AUV and oceanographic monitoring systems.
