Key Features of the IL8M Underwater Connector
1. Eight Male Electrical Contacts
The IL8M features eight precision-manufactured male electrical contacts designed for dependable underwater electrical connections.Its eight-contact configuration allows multiple electrical circuits to be integrated into a single underwater connector interface.Typical applications include:
- Underwater sensor connections
- Electrical power distribution
- Marine instrumentation
- Control and monitoring signals
- Underwater camera systems
- Oceanographic data acquisition equipment
- Subsea robotic platforms
- Offshore electronic systems
Each contact has a nominal current rating of
10 A, subject to the cable configuration and operating conditions.The eight-contact arrangement provides additional connection capacity compared with lower-pin-count connectors.This makes the IL8M suitable for equipment requiring multiple electrical circuits within a compact subsea connection system.
2. SubConn and SEACON Compatible Standard Circular Interface
The IL8M is designed with a mating interface compatible with corresponding SubConn and SEACON Standard Circular 8-pin female connectors.This compatibility makes it suitable for marine equipment manufacturers and offshore operators seeking compatible underwater cable assemblies.The IL8M can be paired with:
- HYSF BH8F female bulkhead connectors
- Corresponding SubConn Standard Circular 8-pin female receptacles
- Corresponding SEACON Standard Circular 8-pin female receptacles
Compatibility should always be verified against the exact connector model, contact configuration, and locking arrangement.
Importante: The IL8M belongs to the Standard Circular Series and is different from the MCIL8M Micro Circular connector.Although both products have eight male contacts, they use different mechanical interfaces and are not interchangeable.
3. Designed for Underwater Depths Up to 6000 Meters
The IL8M is engineered for underwater environments requiring reliable electrical performance under high hydrostatic pressure.The standard connector series supports underwater operating depths of up to
6000 meters of seawater, corresponding to approximately 60 MPa.This makes the IL8M suitable for applications including:
- Deep-sea exploration
- Offshore inspection
- Underwater robotic operations
- Marine scientific research
- Oceanographic monitoring
- Subsea instrumentation
- Underwater observation systems
The maximum operating depth of the complete cable assembly depends on the connector configuration, selected cable, correct mating, and qualification of the assembled system.
4. Durable Molded Neoprene Rubber Construction
The standard IL8M connector features a molded neoprene rubber body designed for demanding marine environments.Neoprene rubber provides flexibility, mechanical durability, and environmental resistance suitable for underwater electrical connections.The molded construction helps protect the cable termination area and provides strain relief where the underwater cable enters the connector body.This design is useful in environments involving:
- Continuous seawater exposure
- Hydrostatic pressure
- Equipment vibration
- Repeated deployment and retrieval
- Routine maintenance and handling
The underwater cable should be routed carefully to avoid excessive bending, pulling forces, or mechanical stress near the connector body.
5. Gold-Plated Electrical Contacts
The IL8M incorporates gold-plated electrical contacts designed for dependable conductivity and stable electrical performance.Gold-plated contact surfaces help maintain reliable electrical connections and support repeated mating cycles under appropriate operating conditions.Before connecting the IL8M to a compatible female receptacle, users should inspect the mating interface.The electrical contacts and sealing surfaces should be kept free from sand, sediment, dirt, and other contamination.Correct mating and maintenance procedures help preserve reliable subsea electrical performance.
6. Standard 1-Meter Underwater Cable
The IL8M is normally supplied with approximately
1 meter of integrated underwater cable.This standard cable length provides a convenient connection to external marine electrical equipment.Typical connected devices include:
- Underwater sensors
- Camera systems
- Lighting equipment
- Electronic control modules
- Oceanographic instruments
- Marine monitoring systems
- Subsea data acquisition equipment
Custom cable lengths can be provided according to project requirements.HYSF SUBSEA can also discuss customized conductor configurations, cable construction, shielding requirements, and termination arrangements for OEM applications.Customers requiring specific cable electrical characteristics should confirm these requirements before production.
7. Wet-Mateable Underwater Connector Design
The IL8M belongs to the HYSF Standard Circular wet-mateable connector family.The connector is designed to support mating and demating in underwater environments when used with compatible mating components.This design is useful for subsea cable replacement, underwater maintenance, and marine equipment servicing.However, wet-mateable does not automatically mean live-mateable.
Electrical power should be disconnected before mating or demating unless the specific connector configuration has been qualified for energized operation.IL8M Technical Specifications
