Raymarine A06039 SeaTalkNG Spur Cable – 1M

Raymarine A06039 – SeaTalkNG Spur Cable, 1M

The A06039 is a 1-metre (3.3 ft) SeaTalkNG spur cable that connects an individual Raymarine instrument, sensor, or electronics device to the SeaTalkNG network backbone. It runs from the spur socket on a T-piece connector (A06028) or 5-way block directly to the SeaTalkNG port on the device, delivering both data and 12 V DC power in a single cable. At 1 metre, it suits devices mounted close to a backbone junction point.

Product Details

• Part Number: A06039
• Brand: Raymarine
• Type: SeaTalkNG Spur Cable
• Length: 1 m (3.3 ft)
• Connector Type: SeaTalkNG spur (5-pin) — device end and backbone spur end
• System: SeaTalkNG / NMEA 2000-compatible network
• SKU: 152-A06039

Compatible Applications

• Connecting any Raymarine SeaTalkNG-compatible instrument or sensor to the backbone at a T-piece spur socket
• Autopilot course computers, instrument displays, wind sensors, depth transducers, and other SeaTalkNG devices positioned within 1 m of a backbone tap
• Vessels using the E22158 SeaTalkNG Backbone Kit or T70134 SeaTalkNG Starter Kit where individual device spur cables are ordered separately
• Replacing a damaged or incorrectly sized spur cable on an existing SeaTalkNG installation

Spur vs. Backbone — What’s the Difference?

The backbone is the main trunk cable that runs the length of the vessel, carrying network data and power. Spur cables branch off the backbone at each T-piece and connect to individual devices. Spur cables use a different, smaller 5-pin connector than backbone cables and are not interchangeable with backbone segments. This A06039 is a spur cable — if you need a backbone segment, see the A06035 3M Backbone Cable or A06036 5M Backbone Cable.

Spur Cable Length Comparison

• A06039 – 1M (3.3 ft) — This product — device close to the backbone junction
• A06040 – 3M (9.8 ft) — Device further from the backbone junction

Parts Desk Insights

Best Use Case: The 1M spur is ideal when your device is mounted directly adjacent to a T-piece or 5-way connector block — for example, an instrument display or autopilot head installed at the helm where the backbone runs right behind the panel. Having the correct spur length avoids excess cable coiled behind the dash and keeps the installation tidy.

Common Issues: The most frequent ordering mistake is confusing spur cables with backbone cables — they use different connectors and serve different roles in the network. Also measure your actual routing distance (including routing around hardware and through conduit) before choosing the 1M length; if the run is at all tight, the 3M spur gives more flexibility. If a device is powered up but not appearing on the network, check that the spur connector is fully seated at both ends — the 5-pin spur connector clicks when properly engaged.

Technical FAQ

Can I use this spur cable as a backbone segment?
No — spur cables and backbone cables use different connector types. Spur cables connect individual devices to the backbone at a T-piece or 5-way block. Backbone cables form the main trunk.

How many spur cables can I run off one backbone?
SeaTalkNG supports up to 50 network nodes. Each T-piece provides one spur connection point; 5-way blocks provide four spur connections plus two backbone connections.

Does the spur cable carry power to my device?
Yes — SeaTalkNG spur cables carry both data and 12 V DC power from the backbone to the connected device, so no separate power wiring is needed for most SeaTalkNG instruments.

Is this compatible with NMEA 2000 DeviceNet devices?
SeaTalkNG spur connectors are Raymarine-proprietary and not directly compatible with DeviceNet connectors. An adaptor such as the A06076 is required for NMEA 2000 DeviceNet devices.
