Furuno WRJ-FIN-CON Waterproof RJ45 Field Connector

Ensuring reliable connectivity on the water starts with the right tools, and the Furuno WRJ-FIN-CON stands out as a game-changer for marine network setups. This field-replaceable waterproof RJ45 connector is engineered specifically for Furuno cables, delivering a secure, weatherproof link to essential components like the HUB102 network hub and TZtouchXL multifunction displays (MFDs). Whether you're dealing with rough seas or constant exposure to salt spray, this connector keeps your data flowing without interruptions.

Key Features That Set It Apart

• IP67-Rated Waterproofing: Fully sealed against water ingress, dust, and corrosion—ideal for harsh marine environments.
• Field-Installable Design: No special tools required beyond basic crimping; assemble on-site for quick repairs or extensions.
• Precision RJ45 Fit: Matches Furuno Ethernet cables perfectly, supporting high-speed data transfer for radar, sonar, and chartplotter integration.
• Durable Construction: High-grade materials resist UV exposure, vibration from engines, and temperature swings from -25°C to +70°C.
• Compact and Low-Profile: Minimizes snag risks on deck while maintaining a professional, streamlined installation.

Why Marine Professionals Rely on It

In the demanding world of boating and fishing, downtime from faulty connections can mean missed opportunities or safety risks. The WRJ-FIN-CON eliminates common pain points like loose plugs or water-damaged Ethernet ports. Boaters report fewer network dropouts during long offshore trips, and technicians appreciate the ease of on-the-spot fixes. It's not just a connector—it's peace of mind for your vessel's nerve center, ensuring seamless communication between your MFD, sensors, and peripherals.

Step-by-Step Installation for Flawless Results

Setting up the WRJ-FIN-CON is straightforward, even for those new to marine wiring. Follow these proven steps to achieve a rock-solid connection:

1. Prepare the Cable: Strip the outer jacket of your Furuno Ethernet cable to expose the twisted pairs, taking care not to nick the wires.
2. Insert Wires: Align the eight conductors into the RJ45 contacts following T568B wiring standard—orange-white, orange, green-white, blue, blue-white, green, brown-white, brown.
3. Crimp Securely: Use a standard RJ45 crimping tool to lock the pins in place.
4. Assemble the Housing: Slide the waterproof gland over the cable, then mate it with the connector body and tighten for an IP67 seal.
5. Test the Link: Plug into your HUB102 or TZtouchXL, power up, and verify link lights for gigabit Ethernet stability.

Pro tip: Always apply dielectric grease to contacts before sealing to boost longevity in saltwater conditions.

Perfect Compatibility for Furuno Ecosystems

Designed with Furuno's marine networks in mind, this connector shines in setups featuring TZtouchXL MFDs for intuitive touchscreen navigation and the HUB102 for expanded Ethernet switching. It supports NMEA 2000 gateways, AIS receivers, and radar overlays without signal loss. Users integrating multiple displays across flybridge and helm stations find it indispensable for creating robust, daisy-chained networks.

Real-World Applications and Success Stories

From commercial fishing vessels tracking hauls in real-time to recreational yachts hosting weekend charters, the WRJ-FIN-CON powers critical operations. Charter captains praise its role in maintaining autopilot and sonar feeds during storms, while offshore racers value the vibration-proof hold during high-speed runs. One skipper shared how it saved their tournament by quickly replacing a flooded connector mid-event.

Maintenance and Troubleshooting Essentials

To maximize lifespan, inspect seals annually and re-grease as needed. Common issues like intermittent links often trace to improper crimps—double-check wire order. If corrosion appears, a simple rinse with freshwater followed by drying prevents escalation. With proper care, expect years of uninterrupted service.

Upgrade your marine electronics setup with the reliability of the Furuno WRJ-FIN-CON—built to endure where others fail.
