Underwater Electrical Connectors for the Defence Industry

The SEACON® Group of companies has the expertise to design, prototype, qualify and manufacture an extensive and diverse range of electrical, optical and hybrid connector assemblies and cable system solutions for many applications within the oil and gas, defense, oceanographic and environmental markets.

Underwater electrical dry-mate connectors

SEACON®'s well established MINI-CON range was originally developed for the purpose of supplying small diameter, high density and high pressure connectors. Dry mateable, this connector series is manufactured from 316 stainless steel as standard, although other materials are available upon request including Titanium and Monel®. The inserts are manufactured from Glass Reinforced Epoxy (GRE) with copper alloy, gold plated contacts although glass sealed inserts are also available for high pressure applications. The MINI-CON series also offers optical and hybrid versions along with PBOF-HP (High Pressure), reversed miniature inserts and self wiping miniatures.

Key features include:

  • Connector type: electrical
  • Mating environment: dry-mate
  • Pressure: up to 16,000 psi (with standard materials)
  • Contacts: up to 203
  • Voltage: up to 5,000 VDC
  • Current: up to 50 amps
  • Materials: 316 stainless steel, glass reinforced epoxy, copper alloy
  • Other features: cable termination additional, PBOF available

Underwater electrical wet-mate connectors

SEACON (europe) Ltd has re-developed its well-known U-MATE range of underwater electrical wet-mate connectors, making it easier to manufacture and incorporating existing proven technology.

The SEA-MATE series has many features including fully interchangeable inserts which offers greater flexibility to the customer with full PBOF capability and increased contact configurations. In addition, this connector range has many of the original features as those of the U-MATE series including, positive keying and proven underwater mating technology and a robust design for harsh subsea environments.

This connector range is manufactured from 316L stainless steel as standard, however other materials are available upon request.

Key features include:

  • Connector type: electrical
  • Mating environment: Wet-mate, with ROV mate option
  • Pressure: up to 7,500 psi
  • Contacts: up to 37
  • Voltage: 600 VDC
  • Current: 10 amps
  • Materials: 316L stainless steel, glass reinforced epoxy, neoprene rubber, copper alloy
  • Other features: cable termination additional, PBOF available

Optical hybrid dry-mate products

As fiber optic communication continues to evolve, the SEACON® Group are able to offer a comprehensive and extensive range of fiber optic products which are designed and manufactured to meet the specific and varied environmental conditions demanded today.

Our OPTI-CON series is a unique design that allows any combination of optical and electrical configurations to suit their individual requirements. The manufacture of all parts in house ensures that each connector is supplied with the highest of standards. This connector range is manufactured from 316L stainless steel as standard, but other materials are available upon request.

Key features include:

  • Connector type: optical hybrid and mating environment: Dry-mate
  • Pressure: up to 7,500 psi
  • Voltage: up to 600 VDC
  • Current: 4 amps
  • Materials: 316L stainless steel
  • Other features: oil filled hose as standard

Military-specification connectors

Our MIL-C-24231 series of connectors are manufactured and tested in accordance with the strict requirements of the Navy specification MIL-C-24231. Available in various shell sizes and contact configurations, plugs can be supplied terminated and molded into water proof cable assemblies or supplied in kit form. In addition, we also offer a GRE (Glass Reinforced Epoxy) overcoated version for applications where cathodic delamination is an issue. This version also offers a GRE backed polyurethane insert which eliminates water leakage through the connector when cable damage occurs. Some versions are also available in GRE Design.

Our M24217 series of hermetic connectors are manufactured and tested to the strict requirements of the Navy specification MIL-C-24217. This series of connectors is widely used in many undersea and military applications and is also suitable for any operation where pressure, humidity, or temperature are factors of performance. A full range of receptacle mounting styles are available and contact configurations range from single coaxial to 48 size #16 conductors. Some versions also available in GRE Design. As with all SEA CON® connectors, plugs can be supplied terminated and molded into water proof cable assemblies or supplied in kit form.

SEA CON® maintains certified molding facilities in both California and Rhode Island, USA for all Pro 20 requirements.
