Key Features of the IL2F Underwater Connector

1. Two-Pin Female Electrical Interface

The IL2F features two female electrical contacts designed to establish a secure mating connection with compatible two-pin male connectors.The female contact arrangement provides a practical electrical interface for applications requiring two conductors.Typical configurations include:

• DC power supply and return
• Two-wire underwater sensors
• Low- and moderate-power equipment connections
• Basic electrical control circuits
• Simple analog signal transmission
• Subsea instrument power cables

The connector should be selected based on the actual voltage, operating current, cable conductor size, and electrical characteristics of the connected equipment.

2. SubConn-Compatible Standard Circular Design

The IL2F is manufactured as part of the HYSF Standard Circular underwater connector family.Its mating interface is designed to be interchangeable with corresponding connectors from established subsea connector brands, including SubConn, SEACON, and Burton.This compatibility helps reduce equipment redesign requirements when replacing existing connectors or integrating new cable assemblies into established underwater systems.For reliable mating, the exact connector series, contact arrangement, gender, and locking configuration must be verified.

3. High-Pressure Watertight Construction

The HYSF Standard Circular Connector Series is engineered for demanding underwater environments.The series is designed for pressure resistance up to 60 MPa, corresponding to approximately 6,000 meters of seawater depth, when the connector and cable assembly are appropriately configured and qualified.Its molded construction helps protect internal electrical connections from water ingress and external environmental conditions.Actual operating depth depends on the complete connector assembly, cable specification, mating configuration, and installation quality.

4. Gold-Plated Female Contacts

The IL2F uses gold-plated electrical contacts to provide dependable electrical conductivity and resistance to contact-surface corrosion.Gold-plated contacts are particularly valuable in underwater electrical connectors because stable contact performance is essential for long-term equipment operation.Proper inspection, cleaning, and mating procedures help preserve contact integrity throughout the connector’s service life.

5. Durable Neoprene Connector Body

The Standard Circular series uses molded elastomeric construction, with neoprene commonly used for the connector body.This material provides flexibility and mechanical protection for underwater cable connections.The molded design integrates the cable termination and connector body into a watertight assembly.It is suitable for subsea cable harnesses, permanently installed equipment, and detachable electrical interfaces.

6. Wet-Mateable Connector Technology

The IL2F belongs to a wet-mateable underwater connector series.This means the connector system is designed to support underwater connection and disconnection when operated according to the manufacturer’s procedures.However, wet-mateable connectors should not automatically be considered suitable for mating or demating under electrical load.Unless the specific assembly has been approved for energized mating, disconnect power before connecting or separating the mating interfaces.

7. Standard 1-Meter Cable

The standard IL2F is supplied with a 1-meter cable.This configuration is suitable for many underwater equipment installations and allows straightforward integration with marine electrical systems.Customized cable lengths can be supplied to accommodate different equipment layouts and deployment requirements.

8. Custom Cable Assembly Options

HYSF SUBSEA supports different cable assembly configurations for subsea applications.Potential customization options include:

• Alternative cable lengths
• Different conductor cross-sectional areas
• Application-specific cable outer diameters
• Custom wire assignments
• Cable assemblies with connectors at both ends
• Open-ended cable configurations
• Customized molded cable assemblies
• Specialized subsea cable harnesses

All customized assemblies should be evaluated for electrical loading, water pressure, mechanical strain, and environmental suitability.

IL2F Standard Cable Wiring

The HYSF Standard 2-Pin series uses the following standard wire colors:

Pin Number	Standard Wire Color
Pin 1	Red
Pin 2	Black

This arrangement simplifies wire identification during cable installation, electrical testing, and subsea equipment integration.For suitable two-wire DC applications, the red conductor may be assigned to positive voltage and the black conductor to the negative or return circuit.These functional assignments are examples rather than mandatory polarity definitions.The final pin assignments must match the electrical diagram of the connected equipment.Custom wiring configurations may be specified for different applications.
