RMG-2-FSD 2-Socket Female Rubber Molded Dummy Connector

Product Overview

The HYSF SUBSEA RMG-2-FSD 2-Socket Female Rubber Molded Dummy Connector is a protective underwater connector accessory designed for commercial diving systems, diver umbilical communications, offshore equipment, and subsea electrical connections.Featuring a two-socket female mating configuration and a molded neoprene rubber body, the RMG-2-FSD is designed to protect compatible male connector interfaces when the electrical connection is not in use.As part of the RMG Rubber Molded Connector Series, the RMG-2-FSD serves as a protective dummy plug for RMG-2-MP male in-line connectors and compatible two-contact male bulkhead connectors.The RMG-2-FSD is particularly useful for commercial diving applications where underwater connectors may be exposed to seawater, salt deposits, dust, moisture, debris, and mechanical handling during installation, equipment storage, transportation, and maintenance.Unlike a standard electrical cable connector, the RMG-2-FSD is a protective dummy connector without an external electrical cable. Its primary function is to protect an unused male mating interface rather than transmit electrical power or communication signals.The reference design uses special molded neoprene rubber, providing a flexible protective construction suitable for marine and subsea equipment.The SEACON RMG-FSD reference configuration specifies a mated pressure rating of up to 20,000 psi, approximately 1,379 bar, when installed on a compatible male connector.The RMG-2-FSD is suitable for protecting compatible male electrical connectors used in diver umbilical communication systems, offshore diving equipment, underwater cameras, subsea instruments, and marine electrical installations.HYSF SUBSEA provides RMG-compatible underwater connectors, rubber molded dummy plugs, protective connector caps, and customized subsea cable assemblies for commercial diving and marine engineering applications.

Key Features and Benefits

1. Two-Socket Female Dummy Configuration

The RMG-2-FSD features a two-socket female mating interface designed for compatible RMG two-contact male connectors.Its female dummy configuration allows it to cover and protect the male connector interface when the mating electrical cable connector is disconnected.The two-contact RMG interface uses different contact sizes, typically one #10 and one #14 contact position.Key characteristics include:

• Two-socket female dummy configuration
• RMG rubber molded connector interface
• Compatible two-contact male mating arrangement
• Protective connector design
• Cable-free construction
• Suitable for RMG series connector protection
• Compact underwater protective accessory

The dummy connector is intended for mechanical protection and sealing rather than electrical transmission.

2. Protective Dummy Plug for Male Connectors

The primary function of the RMG-2-FSD is to protect exposed male connector interfaces.When an RMG male connector is disconnected from its normal female cable connector, its mating interface may be exposed to environmental contamination.The RMG-2-FSD provides a protective cover for the compatible male connector.Key benefits include:

• Protection against dust and debris
• Reduced exposure to seawater contamination
• Mechanical protection for male connector pins
• Protection during equipment storage

7. Protection During Equipment Storage

Underwater connectors are often disconnected during equipment storage, inspection, and maintenance.Leaving connector interfaces exposed may allow dust, moisture, salt deposits, and foreign particles to accumulate.The RMG-2-FSD provides a practical protective accessory for compatible male connectors during periods when the electrical connection is not required.

8. Protection During Transportation

Marine electrical equipment may experience repeated handling and movement during transportation.Exposed connector pins can be damaged by accidental contact with tools, surrounding equipment, or packaging materials.The RMG-2-FSD provides a protective cover for the mating interface during transportation and equipment handling.

9. Cable-Free Protective Design

The RMG-2-FSD is a dummy connector rather than a functional electrical cable connector.It does not require an external cable to perform its protective function.Key characteristics include:

• No electrical cable required
• No external conductor termination
• Protective mating interface
• Compact rubber molded construction
• Convenient installation and removal
• Suitable for equipment maintenance

This distinguishes the RMG-2-FSD from the RMG-2-FS female in-line cable connector.

10. Protection for Male Bulkhead Connectors

Male bulkhead connectors are commonly installed on underwater instruments, control housings, and marine electronic equipment.When the external cable connector is removed, the exposed bulkhead interface may require protection.The RMG-2-FSD can provide a protective dummy interface for compatible male bulkhead connectors.Typical applications include:

• Underwater instrument housings
• Marine equipment panels
• Subsea control equipment
• Diving communication systems
• Offshore monitoring equipment
