Overview

The Garmin 010-11078-00CASE is a 10-pack of NMEA 2000 T-connectors used to add devices to a NMEA 2000 backbone.

Each T-connector installs inline on the backbone and gives you one drop connection point for a display, sensor, gateway, or other NMEA 2000 node. This revised body is offset by 45 degrees, which helps when space is tight behind a helm, inside a console, or in a rigging chase where straight connectors can force a hard cable bend.

Key features

• 10-pack of NMEA 2000 T-connectors for building out a network or keeping spares for service work.
• 45-degree offset body for better clearance behind panels and cleaner cable routing in crowded installs.
• Standard NMEA 2000 Micro-C style connectors to match common backbone and drop cables.
• One device port per T-connector for tying in electronics without breaking the backbone layout.
• Supports proper linear backbone construction where each device connects through its own T-connector.

What's included

• 10 NMEA 2000 T-connectors

Compatibility and fit

This connector is for NMEA 2000 networks that use Micro-C style cabling. It is meant for plug-in NMEA 2000 backbone and drop connections, not bare-wire splices or NMEA 0183 wiring.

On most boats, these are mounted behind the dash, inside the console, or in a dry wiring run where the backbone is supported and strain on connectors is kept low.

Installation and setup

Install a T-connector where you need a new connection point by separating the backbone at that spot and inserting the T inline. Connect the device drop cable to the remaining port and secure the backbone so vibration does not work the connectors loose over time.

A clean NMEA 2000 layout keeps terminators at the two ends of the backbone and avoids leaving any connector open to moisture. If a port is temporarily unused during a staged install, cap it with a protective cover.

Use cases on board

This 10-pack is a good match for refits, multi-station boats, and installs where several sensors and displays will share one NMEA 2000 backbone. It is also handy for service trucks and technicians who want consistent network hardware on hand for troubleshooting and expansions.

Maintenance and care

Keep connections clean, hand-tighten coupling nuts, and support the cabling so the connector body is not hanging under load. In saltwater boats, a quick wipe-down during seasonal checks helps prevent grime buildup around the connector collars.
