SeaTalk NG T-connector

The A06028 T-connector is an essential component for building or extending a Raymarine SeaTalk NG navigation network. It serves as a junction point to add a device, such as a multifunction display or a sensor, to the backbone line of your network.

The connector has a color code for easy installation:

Two blue ports: They are reserved for connecting backbone cables to ensure network continuity. One white port: It is used to connect the spur cable leading to the device you wish to add to the network.

Yes, the SeaTalk NG network is electrically compatible with the NMEA 2000 standard. However, the connectors are physically different. To connect a device from another brand with a standard NMEA 2000 plug (Micro-C), you will need a Raymarine SeaTalk NG to NMEA 2000 adapter cable.

SeaTalk NG is Raymarine's proprietary wiring system based on the NMEA 2000 protocol. It uses specific connectors with color coding and a bayonet locking system to simplify installation and improve reliability in marine environments. Data is transmitted in NMEA 2000 format.

Yes, the bayonet locking system ensures a robust mechanical connection and perfect watertightness. This protects the electrical contacts from moisture, spray, and corrosion, which is essential for long-lasting installations in a marine environment.

No, no specific tool is required. Installation is done by hand using the connection and locking system via simple collar screwing.

Yes, that’s even the principle behind the SeaTalk NG backbone construction. You can chain T-connectors to create as many connection points as needed for your various navigation instruments.

No, this connector is not directly compatible with the SeaTalk1 (or SeaTalkHS) network. To integrate SeaTalk1 devices into a SeaTalk NG network, you must use a specific Raymarine conversion gateway.

The backbone is the main cable running through the boat that distributes data and power across the entire network. T-connectors branch off this backbone to allow individual devices to connect via drop cables.

The manufacturer reference for this Raymarine SeaTalk NG T-connector is A06028.

No, the T-connector itself does not require a termination plug. However, the full SeaTalk NG network must have a termination plug (terminator) at each of its two ends to function correctly.

You can connect any SeaTalk NG or NMEA 2000 compatible device (via an adapter), such as:

A multifunction display (MFD)
A GPS antenna
An autopilot
A wind, speed, or depth sensor
A VHF radio

Yes, the SeaTalk NG network carries both data and a 12V DC power supply. This connector can therefore power connected devices via the split cable, within the network’s power capacity limit.

The weight of this T-connector is approximately 22 g.

No, not directly. The white port is in SeaTalk NG format. To connect a drop cable with a standard NMEA 2000 Micro-C connector, you must use a SeaTalk NG to NMEA 2000 adapter cable.

This is an official Raymarine product, designed specifically for its SeaTalk NG ecosystem.

No, the electrical orientation does not matter. You can install it in the orientation that best suits your setup and cable routing, provided the blue wires are on the backbone and the white wires on the spur.

Yes, as a general rule, every device (display, sensor, etc.) you want to add to your SeaTalk NG backbone network requires its own T-connector to connect.

No, this connector is designed to add a spur. To extend a backbone, you must use a SeaTalk NG backbone cable of the desired length and a junction connector (I-connector) if needed, or simply a longer cable.

The A06028 product packaging contains only the SeaTalk NG T-connector. The backbone cables, spur cables, and end caps are sold separately.
