IL16F 16-Pin Female Inline Underwater Connector – SubConn Compatible Standard Circular Series

Product Overview

Сайт HYSF SUBSEA IL16F 16-Pin Female Inline Underwater Connector is a high-performance, wet-mateable subsea electrical connector designed for reliable multi-channel power, signal, and control connections in demanding marine environments.As part of the HYSF Standard Circular Connector Series, the IL16F features sixteen gold-plated female electrical contacts, a durable molded neoprene rubber body, and an integrated underwater cable.Engineered for underwater applications at depths of up to 6,000 meters (60 MPa), the IL16F provides a dependable electrical interface for subsea equipment operating under high hydrostatic pressure.The connector supports a rated voltage of 550V AC/DC and 10A per contact, making it suitable for underwater instrumentation, marine electronics, power distribution, control systems, and multi-channel signal transmission applications.The standard IL16F is supplied with approximately 1 meter of underwater cable, while customized cable lengths, conductor configurations, and complete subsea cable assemblies are available for specific engineering requirements.The IL16F is designed to mate with the BH16M 16-Pin Male Bulkhead Underwater Connector and is compatible with corresponding SubConn and SEACON Standard Circular connector interfaces.Its high-density sixteen-contact design makes it particularly suitable for remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), underwater cameras, sonar systems, oceanographic instruments, offshore monitoring equipment, and subsea control systems.

Key Features and Benefits

1. High-Density 16-Pin Female Electrical Interface

The IL16F incorporates sixteen precision-manufactured female electrical contacts within a single Standard Circular mating interface.This configuration allows multiple electrical circuits to be connected through one underwater connector.The sixteen-contact design is useful for applications requiring:

• Multiple underwater sensor connections
• Marine instrumentation circuits
• Electrical control signals
• Auxiliary power connections
• Subsea monitoring equipment
• Underwater robotic systems
• Oceanographic data acquisition
• Multi-core underwater cable assemblies

Compared with lower-pin-count underwater connectors, the IL16F provides additional circuit capacity while maintaining a standardized subsea connection interface.Using one multi-contact connector may also reduce the number of separate electrical connection points required in an underwater system.The actual contact assignments depend on the electrical requirements of the connected equipment.

2. 10A per Contact Electrical Rating

The HYSF IL16F belongs to the Standard Circular 12/16/25 Pin connector family.The 16-pin configuration has a catalog-rated current of 10A per contact, together with a rated voltage of 550V AC/DC.These electrical specifications make it suitable for appropriate power, control, and instrumentation applications.The connector can support multiple electrical circuits within its rated limits.However, the permissible current in a completed cable assembly depends on additional factors, including:

• Cable conductor cross-sectional area
• Cable length and voltage drop
• Number of simultaneously loaded contacts
• Operating temperature
• Cable construction
• Electrical termination quality
• Installation conditions

For applications requiring several contacts to carry continuous current simultaneously, the complete cable and connector assembly should be evaluated to ensure that conductor temperatures and voltage drops remain within acceptable limits.

3. SubConn and SEACON Compatible Interface

The IL16F is designed for mating compatibility with corresponding SubConn and SEACON Standard Circular 16-pin connector configurations.This compatibility makes it suitable for customers developing new underwater equipment or replacing existing compatible subsea cable assemblies.Typical applications include:

• Replacement underwater cable connectors
• Marine equipment maintenance
• ROV electrical system upgrades
• OEM underwater equipment
• Offshore instrumentation
• Subsea monitoring projects
• Custom marine cable assemblies

Before using the IL16F with another manufacturer’s connector, the exact mating model, contact configuration, mechanical interface, and locking arrangement should be verified.Important: The IL16F belongs to the Standard Circular Series and is different from the MCIL16F Micro Circular connector.These two products have different physical mating interfaces and electrical specifications.They should not be treated as interchangeable.

4. Designed for Deep-Sea Operation up to 6,000 Meters

The HYSF Standard Circular connector family is engineered for demanding underwater environments.The series supports pressure capability up to 60 MPa, approximately equivalent to 6,000 meters of seawater depth.This deep-water capability makes the IL16F suitable for consideration in applications such as:

• Deep-sea exploration
• Offshore inspection
• Seabed monitoring
• Underwater scientific research
• Subsea robotic operations
• Oceanographic instrumentation
• Marine environmental monitoring

The molded connector body is designed to protect the electrical termination area from seawater exposure.Actual operating depth depends on the complete connector assembly, mating interface, cable construction, and applicable pressure qualification.For critical deep-sea applications, the complete cable assembly should be appropriately tested and qualified for the intended operating conditions.

5. Wet-Mateable Underwater Connector Design

The IL16F belongs to HYSF SUBSEA’s wet-mateable Standard Circular connector family.Its mating interface is designed to support connection and disconnection in underwater environments when operated according to the applicable procedures.Wet-mateable connector technology is useful for underwater equipment requiring:

• Periodic cable replacement
• Sensor maintenance
• Subsea instrument servicing
• Modular system integration
• Underwater equipment reconfiguration

The ability to connect compatible underwater connectors without completely drying the mating interface can simplify appropriate subsea operations.However, wet-mateable does not automatically mean live-mateable.Electrical power should be disconnected before mating or unmating unless the specific connector assembly has been approved for energized operation.

6. Durable Molded Neoprene Rubber Construction

The standard IL16F uses a molded neoprene rubber body designed for demanding marine environments.Neoprene rubber provides flexibility and mechanical resilience, making it suitable for underwater cable connector applications.The molded construction integrates the electrical contact assembly with the underwater cable.Its principal advantages include:

• Watertight molded construction
• Protection of internal electrical terminations
• Mechanical flexibility
• Resistance to routine marine handling
• Integrated cable transition
• Suitable construction for underwater environments

The molded cable entry helps provide mechanical support between the connector body and the attached cable.Proper cable routing and strain relief remain important to prevent excessive bending, twisting, or pulling forces.

7. Gold-Plated Female Electrical Contacts

The IL16F features sixteen gold-plated female electrical contacts.Gold plating provides a conductive contact surface and helps reduce oxidation.Stable contact performance is particularly important for underwater instrumentation and electronic control systems.The recessed female contact arrangement is designed for reliable engagement with corresponding male connector contacts.Before mating the connector, users should inspect the mating interface for contamination, visible damage, or foreign particles.Correct handling and maintenance can help preserve the electrical performance of the connector throughout its service life.

8. Standard 1-Meter Cable with Customization Options

The standard IL16F configuration includes approximately 1 meter of integrated underwater cable.This provides a practical cable-mounted electrical interface for marine equipment.HYSF SUBSEA supports customized underwater cable assemblies according to project requirements.Possible customization options include:

• Customized cable lengths
• Different conductor sizes
• Alternative cable outer diameters
• Shielded cable constructions
• Customized wiring assignments
• Special cable jacket materials
• Connector-to-connector cable assemblies
• Open-ended cable terminations
• Customer-defined cable identification
• OEM subsea electrical harnesses

Cable specifications should be selected according to electrical loading, mechanical requirements, operating depth, and installation conditions.
