The Raymarine A06028 is a 3-way T-piece connector designed specifically for SeaTalkng networking. It allows a single white SeaTalkng spur cable (connecting to an individual device like a display, instrument, or sensor) to be easily connected to the main blue SeaTalkng backbone cable. The T-piece provides two blue ports for the backbone (allowing the network to continue) and one white spur port. It features locking collars and key-ways to ensure secure, reliable, and correctly oriented connections, simplifying the expansion and customization of a marine electronics network.
Technical Specification
1. General Characteristics:
- Model Number: A06028
- Type: 3-Way T-Piece Connector
- Function: Connects one SeaTalk$\text{ng}$ spur cable to the SeaTalk$\text{ng}$ backbone.
- Compatibility: Fully compatible with Raymarine SeaTalk$\text{ng}$ network components and, by extension, NMEA 2000 devices (via compatible cabling/adapters).
- Manufacturer: Raymarine
2. Physical Specifications:
- Material: High-grade marine-grade plastic, designed for durability in the marine environment.
- Color: Typically black or dark grey.
- Connector Type: Raymarine SeaTalk$\text{ng}$ proprietary connectors.
- Number of Ports: 3
- 2 x Blue Ports: For connecting to the main SeaTalk$\text{ng}$ backbone cable (allowing the backbone to continue).
- 1 x White Port: For connecting to a SeaTalk$\text{ng}$ spur cable (leading to an individual device).
- Locking Mechanism: Features locking collars that rotate to secure cable connections, preventing accidental disconnections due to vibration or movement.
- Key-ways: Connectors have key-ways to ensure correct orientation and polarity when connecting cables.
- Dimensions & Weight: (Approximate, as direct datasheets for this specific small component are rare, but generally very compact and lightweight)
- Dimensions: Roughly 1″ x 1″ x 1″ (approx. 25mm x 25mm x 25mm).
- Weight: Very light, typically less than 1 ounce (approx. 28 grams).
3. Electrical Specifications (Passive):
- Power Handling: As a passive connector, it simply passes through the power (typically 12 VDC) and data signals present on the SeaTalk$\text{ng}$ backbone to the connected spur device. It does not consume power itself.
- Data Protocol: Designed for the NMEA 2000 data protocol (which SeaTalk$\text{ng}$ is based on), supporting high-speed data transfer (250 kbit/s).
- Wire Count: SeaTalk$\text{ng}$ cabling itself typically contains 5 wires for data and power (2 for CAN high/low data, 2 for power +/- and 1 for SeaTalk1 data). The connector is designed to correctly route these.
4. Environmental Specifications:
- Ingress Protection (IP Rating): Designed for an internal boat environment. While not typically rated for immersion, the connections are designed to be splash-resistant when properly connected with SeaTalk$\text{ng}$ cables. It’s built for the typical conditions within a boat’s cabin or protected areas.
- Operating Temperature: Suitable for typical marine operating temperatures (-15°C to +55°C).
