Description
NMEA 2000 T-Connector – 1-Way Extension Block
As the NMEA 2000 network expands beyond the 3-device limit of Digital Yacht’s NMEA 2000 Starter Kit, users can use one of these single T-pieces to add devices. With male > female > female connectors, multiple T-pieces can be plugged together or added to the 4-way T-piece included in the starter kit. The lower “drop cable” connector is female so that there are no exposed pins when the drop cable is removed.
*Digital Yacht can supply NMEA 2000 cables and connectors to expand the NMEA 2000 to whatever size is needed (up to the maximum 50 NMEA 2000 device limit).
Features:
- NMEA 2000 Single T-Piece
- Standard “Micro C” connectors make it very easy for future network expansion
- Metal connectors improve reliability
- Waterproof rating of IP68
