Classification and Main Types of ROV Connectors — The "Deep-sea Interfaces" Selected as Needed

ROV connectors can be classified by connection environment, functional application and structural form. Different types are suitable for various operation scenarios. Below is an analysis of core classifications and mainstream models.

1. Classification by Connection Environment

Dry Mate Connectors
Features: Mating must be completed in dry environments such as on deck or inside cabins. They feature excellent sealing performance and cost advantages.
Application: Fixed equipment on ROV main body, including main control boards and built-in sensors.

Typical Model: Amphenol Submariner 5500 Series.

Wet Mate Connectors
Features: Allow direct mating and unmating in deep sea, equipped with automatic sealing and water drainage structure, enabling quick replacement of underwater equipment.
Application: Connection of external manipulators, sensors and umbilical cables.

Typical Models: Teledyne RS4/RS8, TE ALL-WET Series.

2. Classification by Functional Application

Power Connectors

Designed for high-current transmission, applicable to thrusters and high-voltage lights. Example: VideoRay 5-pin thruster connector (48V DC).

Signal & Data Connectors

Multi-core design, integrated with RS-485, Ethernet and optical fiber signals. Example: VideoRay 9-pin accessory connector (supporting ETH, 24V and RS-485).

Hydraulic Connectors

Transmit hydraulic power to drive manipulators and valves. With pressure resistance up to 15000PSI, they are widely used in deep-sea oil and gas operations.
