NMEA 2000 Micro-C 5-Pin T-Connector

Reliable Device Connection for Marine NMEA 2000 Networks

The NMEA 2000 Micro-C 5-Pin Waterproof T-Connector is designed to create a dedicated device connection point within marine CAN bus networks.

Featuring a compact T-shaped structure, the connector provides two backbone interfaces and one device drop interface, allowing compatible marine electronics to be connected to the network without interrupting the backbone layout.

The Micro-C 5-pin connection format makes it suitable for marine navigation, instrumentation, monitoring and sensor systems where standardized, detachable network connections are required.

For boat builders, marine electronics manufacturers, system integrators and maintenance providers, the T-connector offers a practical way to expand NMEA 2000 networks while keeping wiring organized and serviceable.

How the T-Connector Works

Unlike a conventional electrical splitter that divides one power input into two outputs, this T-connector is designed around a marine network architecture:

Backbone In → T-Connector → Backbone Out
↓
    Device Drop

The two horizontal interfaces continue the network backbone, while the branch interface provides a connection point for a compatible marine electronic device.

This structure helps installers add network devices without rebuilding the main backbone.

Key Features & Buyer Benefits

Built for NMEA 2000 Network Expansion

Marine electronics systems often include several devices communicating through a common CAN bus backbone.

Instead of directly splicing cables into the network, a T-connector creates a defined connection point for each compatible device.

This helps provide:

• Cleaner network architecture

• Easier device identification

• Simplified equipment replacement

• More consistent installation

• Easier network expansion

• Better wiring standardization for OEM boat production

For repeated boat builds, the same T-connector layout can be incorporated into a standardized wiring architecture.

Typical Applications

Marine Navigation Equipment

Suitable for connecting compatible:

• GPS / GNSS receivers

• Chartplotters

• Fishfinders

• Navigation displays

• Marine instruments

Vessel Monitoring Systems

Can be incorporated into compatible networks for:

• Engine monitoring

• Fuel level monitoring

• Tank level monitoring

• Environmental sensors

• Equipment status monitoring

Marine Control Systems

May also be used with compatible:

• Autopilot systems

• Marine control devices

• Instrument displays

• Other NMEA 2000-compatible electronics

Final compatibility should always be confirmed according to the connected equipment and network specification.

Available T-Connector Configurations

Based on the product series, different T-connector configurations may be available.

Standard T-Connector

A compact T-shaped connector used to create one device drop connection from the marine network backbone.

T-Connector with Mounting Feature

Selected configurations may include an integrated mounting point to help secure the connector to a bulkhead, panel or equipment structure.

Male / Female Interface Combinations

Different connector interface arrangements may be available according to the network layout and project requirement.

Exact male/female configuration should be confirmed according to the selected model.

Product Specifications

Important: Electrical ratings, IP protection, materials and environmental performance should be confirmed according to the actual product specification before publication or ordering.

Installation Advantages

Plug-and-Connect Network Expansion

Compatible equipment can be added through a defined drop connection without creating manual field splices.

Easier Network Maintenance

Individual devices can be disconnected for inspection or replacement without dismantling the complete backbone.

Cleaner Cable Management

T-connectors create identifiable network nodes, helping installers organize backbone and drop cables.

Suitable for Standardized OEM Wiring

Boat manufacturers can repeat the same approved network architecture across multiple vessels or equipment platforms.

OEM & Custom Project Support

For OEM boat builders and marine electronics suppliers, connector configurations can be evaluated according to:

• Network wiring diagrams

• Connector samples

• Equipment interface drawings

• Existing NMEA 2000-compatible harnesses

• Required male/female arrangement

• Installation position

• Mounting requirements

• Order quantity

• Packaging requirements

A network diagram is recommended for customized projects to ensure the backbone and device-drop arrangement is correctly defined.

Quality Inspection

Depending on the selected model and order requirement, inspection may include:

• Connector appearance inspection

• Dimensional verification

• Pin-position inspection

• Male/female mating inspection

• Threaded locking inspection

• Electrical continuity testing

• Contact connection verification

• Network wiring verification

• Waterproof testing where applicable

• Mounting structure inspection

• Product labeling and packaging inspection

For OEM projects, confirmed drawings and samples can be used as the reference for batch production.

How to Select the Right T-Connector

Before requesting a quotation, buyers should confirm:

1. Micro-C 5-pin interface requirement

2. Required male/female connector arrangement

3. Network installation position

4. Backbone cable interface

5. Device drop connection requirement

6. Required mounting method

7. Environmental protection requirement

8. Connected equipment type

9. Required quantity

10. OEM packaging or labeling requirements

Providing a network diagram, connector photograph or physical sample can improve configuration accuracy.

Frequently Asked Questions

What is an NMEA 2000 T-connector used for?

It creates a connection point between the network backbone and a compatible marine electronic device.

Is this the same as a 1-to-2 electrical splitter?

No. The connector is designed around a backbone-and-drop network architecture rather than simply dividing one electrical input into two outputs.

What does the 5-pin Micro-C connector carry?

The pin configuration is used within the CAN bus-based marine network architecture. Exact wiring and pin assignments should follow the applicable network specification.

Can it connect GPS and chartplotter equipment?

It can be used with compatible marine electronics that support the applicable network and connector configuration.

Can the connector be mounted inside the boat?

Selected versions may include a mounting feature for installation on panels, bulkheads or equipment structures.

Is it IP67 or IP68?

The applicable waterproof rating depends on the actual product model, mating condition and verified test specification. The exact IP rating should be confirmed before ordering.

Can the male/female configuration be customized?

Different interface combinations may be available depending on the model and project requirements.
