Mastervolt 77040050 MasterBus Cable 0.5m

Mastervolt 0.5m MasterBus Ultra-Short Communication Patch Cable

The Mastervolt 77040050 is an ultra-short 0.5 meter (1.6 ft) master communication patch cable engineered specifically for daisy-chaining adjacent Mastervolt power conversion equipment, battery monitors, and interface modules within a single electrical locker, switchboard, or helm console. Designed for high-density installations, it handles high-speed CAN-bus data transfer while simultaneously carrying auxiliary DC power to drive peripheral MasterBus displays and sensors without extra power wiring.

Constructed with high-flex CAT5e UTP twisted-pair copper conductors with an oil- and UV-resistant marine outer sheath, the 77040050 comes factory pre-terminated at both ends with heavy-duty RJ45 modular plugs. The short 0.5 meter length eliminates excess cable slack, reducing clutter, strain, and potential signal interference in compact engine room compartments or behind distribution panels.

Key Features

• Short-Run Modular Patching: Ideal 0.5m length connects adjacent MasterBus hardware without excessive cable coils or strain.

• Simultaneous Data & Auxiliary Power Delivery: Transmits high-speed CAN-bus telemetry while supplying power to connected displays and interfaces.

• Factory Pre-Terminated RJ45 Connectors: Precision-crimped modular connectors ensure secure plug-and-play mating with native MasterBus dual ports.

• High Noise Rejection Geometry: Balanced twisted-pair construction isolates sensitive serial communication from high-frequency alternator, inverter, or charger ripple.

• Heavy-Duty Marine Outer Jacket: Flexible, oil- and flame-retardant outer shell protects internal conductors against marine atmosphere and engine room ambient heat.
