NMEA 2000 T-Piece Polarity (80-911-0059-00)
The 80-911-0059-00 is a standardized marine-grade NMEA 2000 Micro-C T-piece (tee connector) designed to expand NMEA 2000 (N2K) and CZone network backbones by adding single spur/drop connection points. Engineered with exact physical keying and standardized pin polarity, this connector prevents accidental reverse-polarity cross-wiring of power (12V DC) and CAN bus data signals when adding instruments, displays, or sensors to the network trunk.
Constructed to withstand harsh marine and engine room environments, the T-piece features gold-plated copper alloy contact pins housed within a high-impact, UV-stabilized polymer shell. Threaded Micro-C interfaces with internal rubber O-rings ensure an IP67 waterproof seal, protecting sensitive electronic signals against saltwater spray, dust, and engine vibration.
Key Features
-
Standardized Pin Polarity & Keying: Built-in physical keyways guarantee correct polarity alignment across data (CAN_H / CAN_L) and power (V+ / V-) connections.
-
Network Backbone Expansion: Provides one drop/spur port while allowing continuous pass-through of the main network backbone cable run.
-
Corrosion-Resistant Contacts: Gold-plated copper alloy contacts provide high signal conductivity and long-term oxidation protection.
-
IP67 Submersible Rating: Threaded coupling nuts with internal elastomeric O-rings form a dust-tight, waterproof seal when fully mated.
-
Universal Micro-C Standard: Fully compatible with standard NMEA 2000 Micro-C devices, drop cables, backbone cables, and power taps.
