Identify Ancor NMEA 2000 Power Tees, Cables & Connectors
When sorting NMEA 2000 marine-network parts, first distinguish network power, backbone, and device drop. Ancor marks these connection types differently. A yellow-coupler backbone cable is not the same component as a black-coupler drop cable, even if their lengths look alike.
Recognize the component's job
Red connector: network power
The 270000 is a 1-metre power cable supplied with a tee. It is not the cable used to link two electronics displays.
Yellow connector: backbone
270001, 270002, 270005 and 270010 are backbone sections of different lengths. Read the label and measure the cable.
Tee connectors: branch points
270101 is a single tee and 270103 is a two-way tee. Check the number and arrangement of available connections.
Black connector: device drop
The 270302 is a 2-metre drop cable, used between a compatible electronic device and its backbone tee.
Part number, type and measured length
| MPN | Component | Length | What it does |
|---|---|---|---|
| 270000 | Power cable with tee | 1 m (3.3 ft) | Red-coded power tee that introduces network power |
| 270001 | Backbone cable | 0.5 m (1.6 ft) | Short yellow-coupler backbone section |
| 270002 | Backbone cable | 2 m (6.5 ft) | Yellow-coupler backbone section |
| 270005 | Backbone cable | 5 m (16 ft) | Longer yellow-coupler backbone section |
| 270010 | Backbone cable | 10 m (32 ft) | Longest backbone length in this comparison |
| 270101 | Single tee connector | Connector | One tee connection for a device drop |
| 270103 | Two-way tee connector | Connector | Two drop-cable connections from one tee assembly |
| 270302 | Drop cable | 2 m (6.5 ft) | Black-coupler cable between a device and a tee |
What to examine before reusing a part
- Read the six-digit Ancor part number and compare with the table, particularly when the same-looking cable is available in several lengths.
- Identify the coupler colour and the connection role. Avoid treating yellow backbone cables as device drops.
- Inspect pins, threads, seals, housing and the cable jacket for damage; check whether any terminators or blanking caps are supplied separately.
- Check the existing network topology and the equipment requirements before connecting a component. A tee is not a terminator.
- Review the individual store listing for condition and availability; manufacturer identification does not establish the condition of an individual item.
For a standard NMEA 2000 network, Ancor specifies end termination with one male 270106 and one female 270105 terminator. These are separate items, not assumed to be included with the cables shown. Viewing and pickup at UsedRVParts in Kelowna are by appointment.
Match your Ancor number to a store listing
