Key Features and Benefits
1. Twenty-One-Pin Electrical Configuration
The 5501-2021 features twenty-one female socket contacts in a Shell Size 20 configuration.The high-density contact arrangement provides multiple independent electrical circuits within one subsea connector interface.Typical applications include:
- Multi-channel power connections
- ROV electrical systems
- Subsea control circuits
- Underwater sensor connections
- Marine instrumentation
- Auxiliary equipment connections
- Subsea monitoring systems
- Multi-conductor cable assemblies
- Combined power and signal distribution
The twenty-one female socket contacts are designed to mate with compatible male pin receptacles in the Burton 55 Series.
2. Burton 55 Series Compatibility
The 5501-2021 follows the Burton 5500 Series dimensional and mating interface.The 55 Series is widely used in subsea equipment, ROV systems, offshore installations, and underwater electrical assemblies.Its standardized interface allows compatible cable plugs and receptacles to be integrated into existing subsea systems.The 5501-2021 can be considered as a replacement or alternative for compatible Burton 55 Series cable plug installations.Compatibility should be confirmed against the exact shell size, contact arrangement, keyway, and mating dimensions.
3. Shell Size 20 Configuration
The 5501-2021 uses a Shell Size 20 metal shell with twenty-one electrical contacts.The Shell Size 20 configuration accommodates a high-density contact arrangement while maintaining a practical connector footprint for subsea equipment.It is particularly suitable for applications requiring multiple electrical connections through a single circular connector interface.
4. Twenty-One 18 AWG Conductors
One important feature of the 5501-2021 is its original Burton contact arrangement.The technical catalog specifies:
21 × 18 AWG conductorsThis configuration provides twenty-one independent electrical contact positions within the Shell Size 20 connector body.It is suitable for appropriately designed power, control, instrumentation, and signal circuits.The actual current capacity must be determined according to conductor size, cable construction, operating temperature, conductor bundling, and electrical loading.
5. Straight Cable Plug Design
The 5501-2021 features a straight cable connector plug configuration.Its straight design allows the cable to extend axially from the connector body.This configuration is suitable for conventional cable routing in:
- ROV systems
- Subsea tooling
- Umbilical assemblies
- Underwater control systems
- Marine instrumentation
- Offshore electrical equipment
- Subsea monitoring systems
For applications requiring a 90-degree cable exit, a compatible right-angle connector configuration can be evaluated.
6. Twenty-One Female Socket Contacts
The 5501-2021 features twenty-one female socket contacts.In the Burton 5500 Series connector architecture, cable plugs contain female socket contacts, while compatible receptacles contain male pin contacts.This arrangement provides a defined electrical interface for compatible bulkhead and flange receptacles.The original Burton technical catalog specifies high-conductivity copper-alloy contacts.Contact plating and electrical performance should be confirmed against the approved production configuration.
7. Integrally Molded Elastomer Body
The connector features an integrally molded elastomer body.The molding process bonds the elastomer to the internal metal structure, providing mechanical protection and environmental sealing.The molded construction helps protect the internal electrical contacts and cable termination area.The elastomer-to-metal bonding process also helps prevent water migration through the connector structure.
8. Passivated 316L Stainless Steel Shell
The standard Burton 5500 Series uses passivated 316L stainless steel for its connector shell.This material provides:
- Marine corrosion resistance
- Mechanical strength
- Seawater compatibility
- Structural protection
- Long-term subsea equipment suitability
The stainless steel shell provides a robust mechanical interface for demanding offshore and underwater applications.
9. 600V Standard Voltage Rating
The standard Burton 5500 Series voltage rating is 600 V.This makes the connector suitable for appropriately designed subsea power and control circuits.The wider 5500 Series family also offers selected high-voltage configurations, including 1000 V, 2000 V, and 3000 V options.However, higher-voltage configurations require specific contact arrangements and insulation designs.The standard 5501-2021 configuration should not be assumed to support these higher voltages without separate engineering confirmation.
10. High-Pressure Subsea Capability
The Burton 5500 Series technical documentation specifies a pressure rating of 10,000 psi, approximately 690 bar.The connector family uses rugged metal shells, recessed receptacle pins, and an integrated face-type sealing arrangement.This construction is designed for demanding underwater applications.The complete installed assembly should be evaluated according to the mating receptacle, cable construction, mounting configuration, and operating environment.
11. High-Conductivity Electrical Contacts
The original Burton 5500 Series specifies high-conductivity copper-alloy electrical contacts.The contact design provides a conductive interface for multi-channel electrical connections.The twenty-one socket contacts are designed to mate with the corresponding male contacts in compatible receptacles.Contact plating, resistance, and current-carrying capacity should be confirmed against the approved production configuration.
12. Customized Cable Lengths
The 5501-2021 is a factory-molded cable connector plug.The standard assembly consists of one connector at one end and an open cable end at the other.The cable length is specified through the final part-number suffix.For example:
- 5501-2021-0004: 4 ft cable assembly
- 5501-2021-0010: 10 ft cable assembly
- 5501-2021-0015: 15 ft cable assembly
Customized cable assemblies can be evaluated according to project requirements.Available customization options may include:
- Cable length
- Cable conductor size
- Cable jacket material
- Cable outside diameter
- Conductor identification
- Cable termination
- Customized cable assembly
The exact cable specification should be confirmed before production.
13. Dry-Mate Connection Design
The Burton 5500 Series is a dry-mate underwater connector family.Its mating interface uses an integrated face-type sealing arrangement.The connector should be connected and disconnected in a dry environment, with electrical circuits de-energized before mating or unmating.It should not be treated as a connector designed for live underwater mating operations.
14. Suitable for ROV and Offshore Applications
The 5501-2021 is particularly suitable for underwater equipment requiring multiple electrical circuits through one connector.Potential applications include:
- Work-Class ROV systems
- ROV toolskids
- Subsea umbilical assemblies
