IE2M 2-Pin Male Inline Wet-Mate Underwater Electrical Connector
Product Overview
The
HYSF SUBSEA IE2M Teledyne Impulse IE Series Compatible 2-Pin Male Inline Underwater Connector is a compact wet-mate electrical connector designed for ROV systems, subsea instrumentation, underwater equipment, and offshore electrical applications.Featuring two male electrical contacts and a molded neoprene body, the IE2M provides a reliable electrical connection for compatible underwater equipment.The connector belongs to the Teledyne Impulse IE Underwater Pluggable Series, a product family developed for underwater electrical applications requiring reliable connection and disconnection capabilities.Unlike conventional dry-mate connectors, the IE2M is designed to permit underwater mating and unmating when the electrical circuit is switched off.Its molded neoprene construction provides environmental sealing and mechanical protection, while the compact inline configuration makes it suitable for installations where space and weight are important considerations.The original IE Series technical documentation specifies a maximum series voltage of 300 VDC, a current rating of up to 7 A, and a mated pressure rating of up to 10,000 psi.The standard inline cable configuration is molded onto a 24-inch length of 18 AWG cable. For two-contact configurations, the original documentation specifies SJO cable unless otherwise requested.The IE2M is designed to mate with the compatible IE2F-5/8 female inline connector.It is suitable for ROV electrical systems, subsea tooling, underwater sensors, marine monitoring equipment, and other applications requiring compact two-contact underwater electrical connections.
Key Features and Benefits
1. Two-Pin Male Electrical Configuration
The IE2M features two male electrical contacts within a compact underwater connector body.The two-contact arrangement provides a straightforward electrical interface for power transmission and auxiliary electrical circuits.Typical applications include:
- Underwater power connections
- ROV auxiliary equipment
- Subsea control circuits
- Underwater sensor connections
- Marine instrumentation
- Subsea monitoring equipment
- Offshore electrical systems
- Underwater tooling connections
The contact arrangement provides two independent electrical connection positions.The final conductor assignment and polarity should follow the approved wiring diagram.
2. Wet-Mate Underwater Connection
The IE2M belongs to the IE Underwater Pluggable Series and supports underwater mating and unmating.This allows compatible connector halves to be connected and disconnected underwater without recovering the entire equipment assembly to the surface.The original manufacturer specifies that underwater plugging and unplugging must be performed with the electrical power switched off.Key benefits include:
- Underwater connection capability
- Underwater disconnection capability
- Reduced equipment recovery requirements
- Convenient ROV-assisted maintenance
- Suitable for subsea equipment replacement
- Flexible underwater installation
The connector must be correctly aligned and lubricated according to the manufacturer’s maintenance procedure before mating.
3. Compact Inline Cable Connector
The IE2M is an inline male connector designed for direct integration with an underwater electrical cable.Unlike bulkhead connectors, which are installed through equipment housings, inline connectors are used for cable-to-cable and cable-to-equipment connections.Its compact construction makes it suitable for:
- ROV cable assemblies
- Subsea equipment jumpers
- Underwater instrumentation cables
- Sensor connection cables
- Marine electrical assemblies
- Auxiliary power connections
The inline configuration provides flexibility for equipment manufacturers and subsea system integrators.
4. Molded Neoprene Construction
The original IE Series features molded neoprene construction with improved sealing characteristics.The elastomer body provides mechanical protection around the electrical contacts and cable entry.Its molded structure helps protect the internal electrical connection against seawater exposure when correctly mated.Key characteristics include:
- Flexible molded construction
- Environmental sealing
- Mechanical protection
- Cable entry protection
- Suitability for subsea applications
The original IE Series documentation identifies molded neoprene as the standard connector body material.
5. Reliable Electrical Contact Interface
The IE2M features two male electrical pins designed to mate with the female sockets of compatible IE Series connectors.The original IE Series uses a sealing arrangement incorporating O-rings molded into the female connector.The mating interface is designed to provide electrical continuity and environmental sealing during underwater operation.The contact surfaces must be kept clean and lubricated according to the approved maintenance instructions.
6. Up to 300 VDC Series Voltage Rating
The original Teledyne Impulse IE Series documentation specifies electrical operation up to 300 VDC.This makes the series suitable for appropriately designed underwater power and control circuits.The actual permissible voltage depends on the complete electrical assembly, insulation system, cable construction, and operating conditions.The 300 VDC value should be treated as the original series maximum, not an automatically guaranteed rating for every customized HYSF configuration.
7. Up to 7 A Series Current Rating
The original IE Series documentation specifies a current rating of up to 7 A.The two-contact configuration can be used for suitable power and signal applications within the verified electrical limits.Actual current capacity depends on:
- Conductor size
- Cable construction
- Contact resistance
- Ambient temperature
- Simultaneous electrical loading
- Thermal conditions
- Operating environment
The maximum total current should be confirmed for the complete cable assembly.
8. High-Pressure Subsea Performance
The original IE Series documentation specifies a mated pressure rating of up to 10,000 psi.This pressure capability makes the series suitable for demanding subsea applications when used with compatible mating connectors and correctly assembled cable systems.The actual operating pressure should be verified for the specific connector configuration and complete installation.The 5,000 psi open-face pressure rating listed in the original documentation applies to bulkhead connector designs, not automatically to the IE2M inline cable plug.
9. Standard 24-Inch Cable Assembly
The original IE Series inline connectors are generally molded onto a standard 24-inch length of 18 AWG cable unless otherwise specified.For two-contact configurations, the original documentation identifies SJO cable.This integrated cable arrangement provides a convenient electrical termination and reduces the need for field assembly.Custom cable lengths and cable constructions can be evaluated according to project requirements.
10. Compatible with Other IE Series Connectors
The IE2M is designed to mate with the compatible IE Series female connector.Its primary inline mating counterpart is the IE2F-5/8.The original IE Series documentation also identifies compatible bulkhead configurations and protective dummy plugs.Mechanical compatibility should be checked against the approved connector drawing before installation.
11. Suitable for Repeated Underwater Operations
The wet-mate design supports applications requiring repeated underwater connection and disconnection.This is particularly useful for ROV tooling, underwater sensor replacement, and subsea equipment maintenance.The original manual does not provide a specific guaranteed mating-cycle count for the IE2M, so a numerical cycle-life claim should be confirmed through product qualification.
12. Customization for OEM Projects
HYSF SUBSEA can evaluate customized configurations for subsea equipment manufacturers and system integrators.Potential customization options include:
- Cable length
- Cable conductor size
- Cable jacket material
- Cable outer diameter
- Conductor identification
- Contact configuration
- Electrical wiring arrangement
- Connector body material
- Custom cable termination
- Electrical test documentation
- Hydrostatic pressure test requirements
Customized configurations should be reviewed and approved against the final electrical and mechanical specifications before production.
